Re: [mapserver-users] Error compiling mapserver 5.2 with agg

Hello Luigi,

Today I compiled Mapserver 5.2 and agg 2.5.0 from source and in that
combination the problem does not exist. It seems to me that the problem
is in the 2.4-2.1 version of agg?

I installed agg this way:

wget http://www.antigrain.com/agg-2.5.0.tar.gz
tar -xzf agg-2.5.0.tar.gz
cd agg-2.5.0
make
cd ..
mv agg-2.5.0 /usr/local/src/agg
ldconfig /usr/local/lib

hope this works for you too.

Kind regards,

Milo

[mapserver-users] High resolution printing

[Milo van der Linden]

Hello list!

I have been searching the web for tips and tricks, but basically what I 
need is a method or procedure or (commercial) tool that can enhance my 
mapserver installation to enable high resolution printing.


What I am looking for is the best practice to:

- Add a button to our website
- Let the button start a script or program that processes the active 
layers in the map view based upon the current extent
- Generate a mixture of high-res images and optionally svg or alike for 
linework

- combine the works in a pdf
- present the pdf for download to the user

I would also like to know if there are any commercial, mapserver based, 
solutions for this. I am also willing to hire an expert to achieve this.


Any ideas?

Kind regards,

Milo van der Linden

Re: [mapserver-users] Trouble with IIS/WMS service in ArcGIS

[Milo van der Linden]

Make sure that the directory where the temporary map images /ms_tmp/ are 
stored is accessible by your server's IIS_XXUSER otherwise no images 
will be served.


Don't trust IIS to arrange this for you, you have to set it yourself at 
system level.

I suppose this is more of an ArcGIS question, so I apologize if it's not
appropriate here, but perhaps somebody has a suggestion.  We have a
MapServer WMS service.  It is running on a server which uses IIS instead
of Apache.  We are trying to consume it through ArcGIS.  I can make the
connection in ArcCatalog, and the properties look correct.  But the data
(which is imagery) cannot be seen in ArcGIS, only a white space.  The
spatial extent looks correct.

We had the same imagery in a WMS service, on an Apache server, and it
works fine with ArcGIS.  Does anyone have any suggestions?

Thanks,
Bob

Re: [MAPSERVER-USERS] SLD benefits

[Milo van der Linden]

Usability is also an issue with the mapfile for which no easy clients 
have been developed either. But I feel editing SLD with for instance 
Eclipse (Set syntax highlighting to xml) is more easy and user friendly 
already.


I have heard rumors from the FOSS4G that SLD editting software is being 
developed for geoserver, perhaps this will also be usable for mapserver 
(assuming both systems are strict OGC compliant to the SLD schema)


So I think the best thing is to be patient (give developing teams a 
change) be supportive or help projects develop usable tools for this.


Kind regards,

Milo van der Linden

Re: [mapserver-users] Update: MapServer Documentation Effort

[Milo van der Linden]

Great work!

And excellent that these docs are comming from svn.

I already have a remark in 
http://svn.osgeo.org/mapserver/trunk/docs/mapfile/index.txt;


.. seealso::
   :ref:`introduction` for "An Introduction to the Mapfile"

Is ignored.

I tried to go to trac to see if I could attach a ticket, but I noticed 
trac chokes on ref and seealso too. perhaps there is a trac module for 
the documentation structure used?


Anyhow, 3 thumbs up ;-)!

Re: [mapserver-users] MapServer on Intel Atom?

[Milo van der Linden]

Just out of curiosity,

With what reason would you like to have a mapserver on a mobile device? 
I assume mostly to have some sort of localhost connection from a local 
application, and in that case, I would opt for a solution where one can 
for instance download raster-tiles from a server to the mobile device 
that are then used by the application through more simplified functions, 
for vector the same procedure, download vectors and make them available 
through libraries. Installing a httpserver with mapserver as a cgi app 
sounds like a bit of overkill. Perhaps the mobile app can simply use 
gdal and ogr libraries.

Hi,

You say that your raster layer is slower than vector layers, but do you feel it 
is too slow?  Your image should be served pretty fast by Mapserver.  The key is 
that tiff file is tiled (for zoom-in situation) and that it has overviews (for 
zoom-out case). Could you send the gdalinfo report about your image if you 
suffer from slowness?

Hi, thanks.

The vectors are quite simple. I've never experienced slow 
down when displayed vector data, not even on an old Toshiba 
M20 laptop.


Raster, on the other hand, is always the biggest problem. 
Compared to polygons, my raster is always slower to zoom, to 
pan, etc (despite the size is only 500 Mb). Is displaying 
raster more CPU-intensive or memory-intensive? If I'm using 
Intel Atom, will my raster be affected severely?


Also, can using bigger RAM (let say, 2GB or so) compensate 
for the lack of processing power of Intel Atom?


Thanks again,

Re: [mapserver-users] Postgis data source: quoting table name problem

[Milo van der Linden]

Hello Marco,


If you do not specify ...using unique geoidnd using SRID=28992'
mapserver will search the table for srid information, again sending the
table name in a query to the database as seen in the error message.

I agree that this might be a tiny bug, but it might be a workaround to
define the srid in the DATA clause.

Kind regards,

Milo van der Linden

Re: [Mapserver-users] programming with visual basic .net

I do not want to be rude to the mapserver community, since I moved to
linux 2 years ago I have never abandonned it ;-) but...

If you want to create mapping applications from the dotnet framework,
you might want to consider sharpmap. I have had some really good
experience with their toolkit when I was still programming for windows:

http://sharpmap.codeplex.com/

Maybe it can be of use for you.

Re: [mapserver-users] MapServer Projection Issues (I think).

[Milo van der Linden]

 projectionsprojections... it is what differentiates a
geo-specialist from a "regular" programmer

Hello Jelmer,


The wgs84 layer is correct because the ellipsoid/spheroid is the same as
used by the mercator projection.

We in the Netherlands use the Bessel ellipsoid on our
Rijksdriehoekstelsel so you need a +towgs84 transformation too..

Good luck!

Re: [mapserver-users] NoData Gap between rasters - Tileindex Layer

[Milo van der Linden]

Hello Bartlomiej,

Could you post the command you used for gdalwarp? Perhaps you need to set
one or more parameters (f.i. -r where you set the resampling method) to
process the areas that now result in NODATA.

The complete list of parameters can be found here:
http://www.gdal.org/gdalwarp.html

I don't know if what you try is supported; getting a symbol from a remote

Re: [mapserver-users] Rotate parcel labels so that they are normal to their parcel

[Milo van der Linden]

as far as I know, adding a column in your dataset with the rotation is
the only option.

I have read about a GSoC project for setting rotation that in qGIS,
perhaps if qGIS offers to store the rotation in the data, that would be
a good starting point?
http://blog.qgis.org/node/133

[mapserver-users] ASTER GDEM Mapfile

For those that want to do something with ASTER GDEM's as available at:

http://www.gdem.aster.ersdac.or.jp/

I have a mapfile at:

Which goes up to 300m in height (sorry, the mountains in the Netherlands
do not reach much higher)

Have fun with it!

Re: [mapserver-users] ASTER GDEM Mapfile

[Milo van der Linden]

I downloaded a small set (approx. 1Gb) of the aster gdem around the
Netherlands. You can access it (from qGIS for instance) at
http://dogomaps.net/wms/aster?request=GetCapabilities (demo, no uptime
guarantee)

I also found that the best site to donwload aster is here:
http://www.gdem.aster.ersdac.or.jp/  go to that site and click "SEARCH"
in the left sidebar.

Here you can find an example of openstreetmap (via mapserver) combined
with aster:

http://dogomaps.net/osm_aster.png

I am also trying to find out what is possible with the raw corine
landcover dataset,

http://dogomaps.net/openstreetmap_corine.png

I already noticed corine is good for detecting gaps in the openstreetmap
data. For instance here:
http://dogomaps.net/goese-meer.png

Corine clearly shows (in red) that not all urban area's are present in
OSM. still need to figure out licensing, but since the corine resolution
is so low, I think it will be no problem to use it as change detection
in order to find out if you need to "jump on the bike and go outside" 
as an openstreetmapper.

Re: [mapserver-users] msProcessProjection(): Projection library error. no system list, errno: 13

[Milo van der Linden]

Hello Adrian,

Change the METADATA section of your mapfile from:

"wms_srs" "EPSG:900913"

to

"wms_srs" "EPSG:900913 EPSG:4326 EPSG:"

the wms_srs parameter for the MAP is a collection of space separated
EPSG codes that tells the wms-server what projections it supports.
Please use this space seperated list ONLY at the MAP section, when in
Layers, wms_srs needs to be a single EPSG-code that is native to the
particular layer


Good luck!

Milo van der Linden

Re: [mapserver-users] Glacier symbology

[Milo van der Linden]

Hello Bill,

I cannot provide you with a free glacier icon, although I would love to
draw one. I also need to make a symbol for mangrove forest to use in
conjunction with openstreetmap.

However, you triggered me to share some other information: I find that a
good source ánd a good place to share imagery is openclipart:
(www.openclipart.org) I allready have a set of mapsymbols there:

http://openclipart.org/media/people/milovanderlinden contains symbols in
svg that can be manipulated and re-used at will.

There is also a nice snowflake that could be used as a starting point
for your symbol:

http://openclipart.org/media/files/Kliponius/12422

I added a link to OpenClipArt on the SymbologyExchange.

Kind regards,

Milo van der Linden

Re: [mapserver-users] Tiled PNG doesn't work for WCS (and WMS)

[Milo van der Linden]

Steven,

- tiled png should not be a problem, I use that often.
- It would be good to also set "wms_extent" in your layer defs
- I think that setting the wcs_srs to multiple srs-es at the Layer Level
is not how it should be done. Use a single srs there that corresponds to
the wcs_extent or I guess you will have issues. Set the multiple srs-es
at the wcs_srs and wms_srs on the *MAP* level

Good luck! And send my regards to Mvexel ;-)

Re: [mapserver-users] Tiled PNG doesn't work for WCS (and WMS)

[Milo van der Linden]

Steven,

At openstreetmap some guys have pretty good knowledge in creating
supertiles by stitching smaller tiles together. Perhaps that would be an
option if you do not want to create subdirs..

Re: [mapserver-users] Mapserver CGI 5.4 crashed my app (Windows 2003)

I had my IIS crash so severe after a windows update once that it forced
me to switch to ms4w...

Mostly, it has to do with rights/authentication. Are you sure your IIS
user is allowed to connect to your database?

Re: [mapserver-users] Designing a wrapper around mapserv which can be used with fcgi

[Milo van der Linden]

I have:

- mapserver running as fastcgi
- php running as fastcgi

I am currently setting up, not sure how this is going to end up; but I
have the structure you mention in mind too.

I hope that since both processes are fcgi they will enhance each other?
But testing will have to prove it in the near future.

Re: [mapserver-users] Map from .OSM

[Milo van der Linden]

Mapserver cannot read osm directly. That is also because there is no OGR
adapter(yet) for .osm.

If you really don't want to set up postgis:

http://wiki.openstreetmap.org/wiki/Category:OSM_processing

You can browse throug a variety of export/conversion tools. One might
just create the format you need (shp). You can also consider downloading
ready-made shapefiles from the websites:

http://www.cloudmade.com

or

Dear geetha,

This has nothing to do with mapserver/mapscript, but is a php error. The
dl method is (correct me if I am wrong) a little outdated and has to
specifically be set to ENABLED in the php.ini.

Please google a bit on the dl error and see what parameter you need to
change (sorry that I cannot give you a full answer, but I am on 3G in a

Re: [mapserver-users] Position of label

[Milo van der Linden]

If your AJAX webmap client of choice happens to be OpenLayers, there are 
better ways to do this.


Assuming you don't want the whole world labeled, you might consider 
using a WFS layer instead of a WMS layer. Then you can use OpenLayers to 
create *real* vector layers that can even have effects such as light up 
or resize *and* make the mouse cursor change when moving over a label or 
object. Plus it will give you the option to open up pop-up balloons, 
something you will hardly get done using a raster-layer only.


Otherwise, you are in there on your own. Your ajax script would need to 
translate real coordinates to pixel coordinates, guess label coordinates 
and stuff.. I would not go there if I where you.

[mapserver-users] watermark

[Milo van der Linden]

Hi list,

I am trying to create a watermark on an wms aerial photo layer using the 
following technique:


- Create a new shp for my area of interest
- hatch the shape with an image
- set the image to a very low opacity
- add this shape as layer to my mapfile
- trying to set the layer to "always on top, always on" for the aerial photo

I am failing at the last step, somehow I cannot get the layer to be 
always on. If I do a wms request calling both layers: aerial_photo and 
watermark, I get the effect I want, but when I only call the 
aerial_photo, my watermark is not showing, whether I set it to ON, 
DEFAULT, or OFF.


Is there a way to make sure this layer is always shown? Or am I trying 
to use a wrong technique?


Any help appreciated!

[mapserver-users] Small survey

[Milo van der Linden]

Hello Oliver,

The national government geo-initiative (geonovum) in the Netherlands is 
doing a survey on tiling. I would like to fill in the answers to the 
following questions:


Does mapserver support WMS-C and what version?

Does mapserver support TMS and what version?

Does mapserver support WMTS and what version?

Does mapserver support Google and what version?

Does mapserver support Bing and what version?

Does mapserver support KML and what version?

Does mapserver support ArcGIS Servber and what version?

Does mapserver support Oracle MapViewer and what version?

Any remarks?

Could someone help me fill in these questions?

Re: [mapserver-users] Problem with OpenStreetMap, osm2pgsql, MapServer, OpenLayers and epsg=900913

[Milo van der Linden]

The way you are implementing the combination mapserver / openlayers; you 
are callin mapserver as WMS.


For a WMS server; it is very important that you set the right metadata 
for the map and for the layers. Please read through the documentation at:


http://mapserver.org/ogc/wms_server.html

And if you are still stuck with anything, don't hesitate to ask!

postgresql extension it is not to hard to write a couple of functions 
for the database to make these arrays searchable.

Re: [mapserver-users] Projection problems

[Milo van der Linden]

Funny,

Everytime I read "projection problems" on this list I think: Hey, this might
be someone from the Netherlands.


You mean you would really like to have your bedrijventerreinen like this?

http://www.locatiemonitor.nl/LocationDetails2.aspx?lid=1437

(please wait for the bedrijventerreinen wms to appear)

I created the wms service for locatiemonitor and as I can see, we are
"fishing in the same vijver"

Please read my blog post at
http://blog.dogodigi.net/2010/08/19/dutch-coordinate-system-ellipsoid-correction/

And write a small thank you comment if it helped you solve your issue

;-)

Kind regards,

[Milo van der Linden]

Hello Bas,

That is indeed the trick. In my blogpost I specifically target postgis, but
changing the epsg file is the way to go for mapserver, the parameters stay
the same (of course)

The locatiemonitor was for a previous employer of mine. But it is indeed a
nice tool

Good luck on your implementation!

Fwd: [mapserver-users] Reporting lat/long from projected map units

Are you talking bout a web-app? Do you use a client like OpenLayers? What
programming language(s) do you use? Is your datasource a database? Like
postgis?

If you can get UTM coordinates from the mouseclick, the next best option (in
my opinion) would be to use proj4js:

http://proj4js.org/

Simply embed the js-library ad an event for mouse handling and convert:
screen->utm->4326.

(Sorry, my last posts went straight to you by accident, I prefer to stay on
the list, but gmail for applications not always agrees with me)

proj4js has project pages including documentation on the OSGeo wiki. The
userguide is here:

http://trac.osgeo.org/proj4js/wiki/UserGuide

and it immediately explains what you want

Mmm, that shouldn't be to hard. Let me try;

var source = new Proj4js.Proj(‘EPSG:YOUR_UTM_EPSGCODE’);
var dest = new Proj4js.Proj(‘EPSG:4326’); . . .

// transforming point coordinates
var p = new Proj4js.Point(YOUR_UTM_X,YOUR_UTM_Y);
Proj4js.transform(source, dest, p);

alert(p.x); //WILL ALERT YOUR NEW LON
alert(p.y); //WILL ALERT YOUR NEW LAT

Re: [mapserver-users] GetfeatureInfo-Request in an UTF-8 environment with shapfile in cp-1252

[Milo van der Linden]

Hello Andreas;

What return type of getfeatureinfo are you using?
There are three possibilities: http://mapserver.org/ogc/wms_server.html

1. text/plain
2. text/html
3. gml

If you use text/html; you can set the character encoding to windows ansi:

http://www.w3.org/International/questions/qa-html-encoding-declarations#quicklookup

If you use GML, because it is a "flavour" of XML, mapserver MUST serve
UNICODE:(UTF-8 or UTF-16);http://www.w3.org/TR/REC-xml/#sec-well-formed  So
if the gml output is not converted to unicode; please file a ticket for this
matter in the osgeo trac database.

[mapserver-users] PHP Mapscript, label with self created text

[Milo van der Linden]

Hello people,

I have created a piece of mapscript that takes a key/value pair and creates
class-coloring according to this. This works perfectly well except for one
tiny little thing:

I want to add $v as a label to my classes.

My question is: Is it possible to assign static text to a label? Because if
it is not; I would have to query the underlying layer for it's centroid and
create a text label on top of that layer.

For instance something like:
$theme_label[$i]->set("labeltext", $v);



foreach ($mycollection as $k=>$v) {
$theme_class[$i]=ms_newClassObj($theme_layer);
$theme_class[$i]->setExpression($k);
$theme_class[$i]->set("name",
$theme_class[$i]->getExpressionString());
$theme_style[$i]=ms_newStyleObj($theme_class[$i]);
$tc = $theme->getColourValue($v);
$theme_style[$i]->color->setRGB($tc[0],$tc[1],$tc[2]);
$theme_style[$i]->outlinecolor->setRGB(255,255,255);
//$theme_label[$i]=ms_newLabelObj($theme_class[$i]);
//$theme_label[$i]->set("font", "sans");
//$theme_label[$i]->set("type", "truetype");
//$theme_label[$i]->set("size", 10);
//$theme_label[$i]->set("labeltext", $v);
$i++;
}

Re: [mapserver-users] Heatmap / choropleth from points attributes

[Milo van der Linden]

Turning points into polygons (or voronois) is the "thinking like a GIS
professional" approach. This is valid, but not as good as it can get.
Basically, using imaging techniques would be a better approach.

Perhaps you can take this: http://www.sethoscope.net/heatmap/ as a starting
point? The author has created a nice python script to generate a heatmap.

Re: [mapserver-users] PHP Mapscript, label with self created text

[Milo van der Linden]

Hi Nicol,

Excellent! It works! Now I only have one more issue:

http://www.dogomaps.net/bikkels/index.html?zoom=9&lat=385827.82031&lon=174867.38281&layers=B

The label is duplicated due to the fact that I am retrieving tiles. Any
experience with that?

Sorry! Found it by scroogling a bit:

Set PROCESSING "LABEL_NO_CLIP=ON" per layer. Everything works now!

Re: [mapserver-users] Heatmap / choropleth from points attributes

[Milo van der Linden]

Very nice example Tamas!

In my opinion there is only one extra step needed; a no-color
transparent section in the final image. Do you think this would also
be possible?

Re: [mapserver-users] problem with setting outline width for polygons

Hello Hans ;-)

I have no experience using C# with Mapscript, but have you tried this?

Maybe it has something to do with that your colorvalues should be cast to int32

[mapserver-users] WFS gml:null

[Milo van der Linden]

Hello list!

I have been surfing the list all morning looking for a solution on why 
my mapserver is returning a gml:null.


Couldn't find any documentation.

The problem:

I do a WFS request on a mapfile that contains a esri shapefile. The 
layer I request has a different SRS than the main map.


http://www.myserver.org/cgi-bin/mapserv.exe?map=awfsenabled.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=getFeature&TYPENAME=percelen

it returns

Re: [mapserver-users] WFS gml:null

[Milo van der Linden]

Thank you Bart for the response.

I tried BBOX'n my request.

I tried both:
-  SRS=epsg:4326&bbox=-180,-90,-180,-90
and
- -  SRS=epsg:28992&bbox=0,30,30,60

But none of that did the trick..


Bart van den Eijnden (OSGIS) schreef:

What happens if you add a BBOX filter to your request? You probably need to
specify the coordinates in the SRS of your LAYER.

The BBOX filter defaults to the Map's Extent which could be why it's
returning 0 features since of the projection difference.

Best regards,
Bart

Re: [mapserver-users] The right tool for the job

[Milo van der Linden]

Hello Colin,

Mapserver would be an excelent choice to serve the base map and even 
create the dynamic maps you want.
You can also use the great spatial query possibilities of postGIS to 
create views in the database to create the lines on the fly and then 
serve these views through mapserver.




Colin Wetherbee schreef:

Greetings.

I'm new to using GIS data, and I have a project for which I think GIS 
and MapServer would work well.  I'd like to run the basic idea by this 
list and get your input as to whether I'm choosing the right tool for 
the job.


I have a PostgreSQL 8.2 database with PostGIS extensions installed, 
which stores, in GIS form, coordinates for airports around the world.

Excelent choice!


I also have a rather large Perl web application that accesses other 
things in this database.  This is the application to which I would 
like to add some fancy maps.


Essentially, I'd like a map of the world, 
You can connect to other WMS services such as Demis to display a world 
map, either from a server or from a client (using for instance openlayers)
and I'd like to be able to highlight certain airports and draw 
different types of lines between them, based on dynamic input from the 
user through the Perl application. 
You can use user variables to connect to the mapfile (search for 
"substitute variables" on the mapserver website. I would like to hand 
you the link, but I cannot connect to http://mapserver.gis.umn.edu at 
the moment)
Each web page could potentially include a different sort of map with 
different locations highlighted.  

No problem
At peak usage, I suspect at least 75 maps would need to be generated 
per second, with an average of 30-40 data points and various amounts 
of connecting lines between them per map.
Make sure the server is capable of this with regards to bandwidth, 
memory and processor capacity. This is in essence not a problem for mapserv.


Is this the sort of thing MapServer is good at doing?  I've read some 
of the web site, and really, I can't make heads or tails of quite a 
bit of it, especially with respect to Perl.
I think it is, but it is best to combine it with a strong AJAX viewer to 
get the best dynamic user experience and taking the most (views and 
queries) out of postGIS.


Thanks.

Re: [mapserver-users] The right tool for the job

I would like my first step to be putting a static image on a web site. 
The image would be generated by Perl and returned to the browser as a 
simple image/png.


The method I have in mind follows.

Each user has a set of airports and routes with which they are 
concerned.  This set of airports and routes could change as frequently 
as every 30 seconds.  So, for each map generation request, I would 
dynamically create a map file and store it as TEXT in my PostgreSQL 
database, along with some unique ID.  Then, I would output an  
tag to the browser that includes the unique ID of this 
dynamically-generated map file:

Interesting approach. But you could also try:
http://www.someserver.org/cgi-bin/mapserv.exe?map=ergens.map&REQUEST=getmap&Layers=layer1,layer2,layer3&User=MyUser&Airport=1,5,23,56&airline=KLM&;..

The mapfile is able to read user variables; this means

that the value MyUser that is in the variable User can be addressed in 
the mapfile with %User%


Thus making it possible to have a layer that builds it's content from a 
postGIS query dynamically like:


SELECT(THE GEOM) FROM Airports where ActiveUser=%User

This way you don't need to store mapfiles in the database and let the 
form-variables in your webpage feed the dynamic content of the map.


Read the topic on 
http://mapserver.gis.umn.edu/docs/reference/mapfile/variable_sub


The time stamp can also be set on a layer through a variable like this.







mapImage.pl sees id=1234, pulls map file 1234 out of the database, 
uses the MapServer back-end to generate a map, then outputs this map 
as an image/png.  I think mapImage.pl ends up being pretty simple: 
create a mapserver object, pipe the map file text to it, and get the 
png it generates.  Is that it, or am I thinking too narrowly here?


I may include a time stamp, too, so I can expire map files after some 
length of inactivity.


Does this sound about right?

Thanks for your help. :)

Re: [mapserver-users] Re: user support

[Milo van der Linden]

Hello Brent and Frank,

I hope you don't mind me joining this rather usefull discussion! I 
stepped on it, because the new title triggered me (an example of how 
using a clear title on the mailing list is of importance).


Yesterday I was doing some translation work on the OSGeo website (I 
signed up for the dutch translation) and I noticed all the mailing lists 
that are hosted there, it had me thinking about mailing-lists and the 
value they hold.
Basically, the mailinglists that are most active, such as the mapserver 
list hold a rich set of solutions, answers, tips, tricks and so on. But 
I find them hard to browse. Most items are not categorized and sometimes 
it is hard to show the trees in the forest. But again, a lot of the 
posts are extremely valuable! I ended up looking for software capable of 
importing mailman lists into Google Groups or into forums or into... and 
I came out blank. But this tought is still on my mind.


Next thing I was wondering about was if it was possible to rate answers. 
And if it would be possible to easily transform answers into 
documentation. But I haven't found a real solution yet.


Ok, back to the discussion;


With around 2400 subscribers every question and answer is hitting a lot of 
mailboxes.  Is it really a useful approach?  To some extent it is good because 
it gives others a chance to chime in at different points with suggestions, and 
hopefully some people on the list are picking up hints and new knowledge that 
helps them in the future. But .. well, I often prefer to take debugging session 
off-list with the intent of summarizing final findings to the list. I do this 
despite the prevailing KEEP IT ON THE LIST! mantra of some of our leading 
contributors.
  
Of course users that don't like the ammount of mail hitting can always 
subscribe to get digested mail, I find this convenient enough. And 
compared to the ammount of global video and audio downloads, the traffic 
generated by mailinglists is still a tip of the iceberg, but I 
understand your concern. I like your intention to discuss offline and 
finalize a summary. I often invite users that are stuck to skype-chat 
with me. Then I record the chat as we go along. At the end of a session, 
I pick up the chat history, delete all the chit-chat and store what is 
left for future reference.
  


One of my reasons to send the "back and forth" emails to the
list is to illustrate the method of tracking down the cause
of the problem (divide-and-conquer, isolate the problem,
small test case, etc) .  But this is only valuable if the
new users search the list archive; which I suspect most
don't do (but I have no idea on how to measure this).
Fortunately David Fawcett has a section on the archive on
the "New Users" Mapserver page.
  
This is also a solid approach. Divide and conquer is the biggest 
strength of mailing lists! And indeed new users should be encouraged to 
read documentation.

Summer-of-code is very software development oriented.  For instance, a SoC 
effort cannot be primarily focused on writing documents, providing support, 
etc, except as a by product of software development.  So I don't think this 
problem is very much a SoC solvable one.



Is it possible to have some automated system to classify
archive email based on problem type?  Is it worth it?

This question hits the jackpot for me. classifying, categorization, 
sections with moderators, the possibility for people to rate an answer. 
It is already in the Google Groups, perhaps there is some way this can 
be adapted? The google groups are in a lot of way interesting since they 
offer mail integration, user rating, good insight of the most active 
topics. The only thing they miss is categories like they are on forums, 
maybe a tagging system would be good.

And do some questions go un-answered?  Should we have "support" tickets? Yikes!

I have seen some fair examples of a combination of forums, mailinglists 
SVN-repositories and bug tracking systems; The Joomla Open Source CMS 
forum for instance has a pretty good combination.

Should we "reward" people who respond to questions to encourage better support 
(hmm, or would that cause more noise on the list?)

This could be an option, as long as it doesn't require users to pay for 
accessing the list. One of the most anoying sites on earth I find 
ExpertExchange. They always pop-up first on a google search, but you 
need to sign in and pay 25 dollar a month or so for that one single 
question you have! Yikes on that method too.

Ultimately, I think we need to create better documentation, especially starter and 
troubleshooting documentation so folks can "self serve" through the standard 
problems, and just fallback to other people for the harder stuff.  Helping to write such 
documentation might well be something a paid maintainer could effectively do.

This I would be interested in! More then in payed support. It encourages 
people (like me) to share solutions they found. Now

Milo,

I think it would be very valuable if some people were willing to comb
the mailing list for frequently asked questions and answers and turn
some of them into FAQ entries on the plone site.
If this would be done in a divide and conquer manner, I would be 
interested. It would be a good thing if one could take a seat in some 
sort of board and cover a certain aspect. I would be particulary 
interested in contributing to WMS and WFS sections, as well as postGIS 
integration since this is the area I am trying to make my business in. 
Would it be possible that in return the person maintaining a certain 
area of the documentation could offer commercial support and consultancy 
on his particular field of expertise? Just a taught and trying to 
discover if there is business value in signing up for this. Because in 
the long run, we all need to make at least enough money to live.


I'm bad at writing FAQs because I always write FAQs for the questions
I wish people would ask, instead of the ones they do ask.  :-(  

Hahaha! You gave me a good laugh with this one! I recognize the dillema.


But
someone interested in spending a couple hours contributing to the
MapServer world could review a few weeks email traffic, and pick out
a couple common questions with good answers and digest it into FAQs
to list at:

  http://mapserver.gis.umn.edu/docs/faq
I hereby offer my couple of hours. Would it be an idea to set up a group 
of say 100 people and then divide the list in blocks of say a month?


The answers might even include pointers back into the discussion
threads on the mailing list for additional details.  For those not
wanting to contact Howard for Plone update access, I would even
be willing to add FAQs on their behalf if carefully prepared.
Though getting and using update access to the mapserver site is quite
easy and additional contributors are welcome!

I also wonder if the FAQ list ought to be featured a bit more
prominently on the web site.  I was surprised to discover they are
categorized if you go to the full faq list. I normally just see
them in this view:

Re: [mapserver-users] MapServer consuming 100% CPU

[Milo van der Linden]

You may also try not to use the default DATA connection in the mapfile,
but instead reference the shapefile through CONNECTION TYPE OGR;

Another option would be to convert the data through OGR to mapinfo
files. I am using mapserv - mapinfo tab with 21 roadnetworks for all
public safety districts in the Netherlands containing approx. 150.000
road-segments per district and this works fine. Also make sure that the
zoom-layering for the labels is set to your satisfaction.

Put your shapefile in a spatial database like PostGIS I would suggest and

Re: [mapserver-users] can an ogr tileindex refer to a PG table?

[Milo van der Linden]

Hello Neil,

One thing you can do to create some sort of tileindex that can be part 
of the where clause is create a view in postGIS that contains the 
boundingboxes of a table based upon an attribute:


CREATE VIEW MYBBOX AS
SELECT
table1.uniqueID,
extent(table1.the_geom) as box,
box2d(scale(extent(table1.the_geom),1.01,1.01)) as bbox
FROM
table1
GROUP BY
table1.UniqueID;

Where BOX is the exact extent and bbox is the extent + a little margin, 
this I used to zoom with an area around it because my original MYBBOX 
view was based on a points table.


This view could be used as a helper to build the right queries.



Wouldn't it be more performance effective
Neil Best schreef:
Last fall I got some help for the list on how to use Postgres as a 
source for a tile index that gives locations of raster files on disk 
and that has been working beautifully.


My new question is this:  Is it possible for a tile index location to 
indicate something other than a path to a file, such as a PostGIS table?


The reason that I ask is that I have implemented table partitioning 
for large county-by-county (or smaller) data sets such as SSURGO and 
USDA CLU.  At the outset I convinced myself mistakenly that Postgres 
could leverage spatial check constraints for query planning using the 
constraint_exclusion = on mechanism, but it can't.  It only works with 
fields where the check constraint is based on a straight 
equal/not-equal comparison to a constant, AFAICT.  Neither && 
::geometry or ~ ::text checks work for this reason.


Getting Mapserver to leverage this advanced query planning means 
adding logic to my application to inject appropriate values into a 
WHERE clause in the layer's DATA query string.  To do this I need some 
kind of generalized layer that indicates the spatial organization of 
the attributes used for the partitioning.  This is essentially a tile 
index, so if I could just create a layer of bounding boxes for each 
table and let Mapserver decide which tables it needs to scan rather 
than adding complexity to my application in order to have the query 
planner do the same thing, that would be ideal.


Anybody have any thoughts or experiences to share?  Thanks.

Neil

[mapserver-users] GML request returns unsafe HTML characters?

[Milo van der Linden]

Hello list,

I am also posting this question on the Mapserver mailing list, but
maybe Flamingo is keen enough to have a solution already.

I am identifying features on a WMS layer hosted on Mapserver. When I
inspect the result of an Identify request with Firebug (the greatest
_javascript_ debugger in the world) in FireFox, I see that the request
returns values. But... they contain HTML unsafe characters, aargh!

The metadata for the layer in my mapfile is:

METADATA
  "ows_title" "percelen"
  "ows_srs" "EPSG:28992"
  "gml_featureid" "id" ##REQUIRED
  "wms_feature_info_mime_type"  "text/html"
  "ows_feature_info_mime_type"  "text/html" 
    "wms_include_items" "all"
    "wfs_include_items" "all"
    "gml_include_items" "all"
    END

And the output

[mapserver-users] WMS GetFeatureInfo always returns features from a single layer

Hello list!

My GetFeatureInfo request (shown below) ALWAYS returns only features 
from one single layer. I have a simple question. Is this as designed? Or 
am I doing something wrong?


If it is as designed, I will tell openlayers to loop through the layers 
in a javascript function.

Re: [mapserver-users] OpenLayers and MapServer Itasca Demo

[Milo van der Linden]

Hello Jason,

For OpenLayers and Mapserver to co-op your mapfile has to expose itself
as a WMS server.

For this read the manual at:


Good luck!


Jason Allen schreef:
I just started working with MapServer yesterday and it
rocks!
  
I've been learning my around with the MapServer 5.x Demo App (Itasca)
and while it works fine using HTML templates, I can't get it to play
nicely with OpenLayers.  OpenLayers simply returns blank map tiles.
  
The itasca.map file is stock except that I uncommented the projection
info:
PROJECTION
"init=epsg:26915"
END
  
My OpenLayers setup is very simple as well:

    map.addLayer(layer);
    map.zoomToMaxExtent();
    map.addControl( new OpenLayers.Control.LayerSwitcher() );
    }
  
  
Does anyone have any idea why OpenLayers isn't displaying any data, or
how to troubleshoot this issue?  MapServer logging isn't the most
verbose, and I haven't been able to track down any other clues.

Re: [mapserver-users] Dynamic mapping with CGI parameters

[Milo van der Linden]

Hello Colin,

as I tried to clear to you before, I would go for option 2! Better 
still, I am using option 2 in a lot of real life cases.
Add userid=1234 to the request string (and as you say, pass it through 
perl to sanitize, excelent choice)


And use:

   DATA "line FROM (
   SELECT num, id, line
   FROM jsview_journeyroutes
   WHERE us_id = %userid%
 ) AS foo USING UNIQUE id USING SRID=4326"


I can guarantee you that will work.

Kind regards,

Milo van der Linden


Colin Wetherbee schreef:

Greetings.

I have a fledgling MapServer application that uses PostgreSQL as its 
back-end.  Each set of data I would like to retrieve from PostgreSQL 
is specific to a certain user.  Currently, since the application is 
only in an alpha phase, I have MapServer retrieve the aggregate sum of 
the data in the database and display it on my map.  This isn't going 
to work for the real application, since different users need to see 
different sets of data.


I would like to do one of two things, but I've been poring over the 
documentation today and can't find any way to achieve either.  I would 
very much appreciate some assistance.  My two approaches are as 
follows, but if there are others, I would certainly be open to 
implementing something different.


Approach #1:

Since my application is written in Perl, I could use MapScript in Perl 
to generate bits of maps and return them to the browser as needed.  
Perl would interpret cookies and perform session authentication before 
generating a customized map file to pass along to MapServer.  The Perl 
code [0] would look something like:


sub GetMapPiece()
{
  $req = new mapscript::OWSRequest();
  $req->setParameter("SERVICE", "WMS");
  $req->setParameter("VERSION", "1.1.0");
  $req->setParameter("REQUEST", $something);

  # The next two lines are the important ones...
  my $mapFile = GenerateMapFile({ userid => $someUserId });
  my $mapObj = new mapscript::mapObj($mapFile);

  mapscript::msIO_installStdoutToBuffer();
  my $dispatch_out = $map->OWSDispatch($req);
  return mapscript::msIO_getStdoutBufferString();
}

The problem with this is that, as far as I can tell, I can't create a 
mapObj from anything other than a file on disk.  I would like $mapFile 
to contain the full text of a dynamically created map file, and I 
would then like to be able to create a new mapObj from it.  My 
imaginary GenerateMapFile() function would generate the text for the 
map file, but it would never be saved to disk.


Approach #2:

This would be my preferred method, but from what I've read, I think 
approach #1 is more likely to happen.


This approach entails passing a CGI parameter to mapserv that could be 
substituted somewhere in the map file.  For example, the URL could be:


http://example.com/cgi-bin/mapserv?userid=1234

Then, the map file could contain something like:

DATA "line FROM (
SELECT num, id, line
FROM jsview_journeyroutes
WHERE us_id = {userid}
  ) AS foo USING UNIQUE id USING SRID=4326"

And, MapServer would see "WHERE us_id = {userid}" and, for {userid}, 
substitute the 1234 that was passed into mapserv as a CGI parameter.


Of course, doing this directly would cause nasty SQL injection attack 
problems, but I could properly sanitize the input with Perl.  No big 
deal there.


End Approaches.

Any thoughts on this?

Thanks.

Colin

Re: [mapserver-users] Advice for MapServer project

[Milo van der Linden]

Timothy Mashford schreef:

Thanks to everyone for their input.

I have seen OpenLayers, I am not sure it is suitable as I really
require a zoom-box tool (not shift-click), and also a separate layer
control.
  
The zoombox tool is available. Please check 
http://www.openlayers.org/dev/examples/controls.html, there is a zoombox 
button (just above the pan hand). Click it and start dragging.

I have found GeoMoose to be fairly slow(?), and also full of features
I don't require (e.g. slide zoom), although I guess these could be
removed. The Morton County example is good.

The reason I was thinking dbox.js was that it is fast & simple. But
once I get up to that stage I will investigate all options.
  
I don't know about GeoMoose, but in Openlayers you can retrieve all 
layers at once from a mapserver, or you can add layers through 
javascript. The second will speed up drawing the map because layers will 
be sequentially loaded. If your base layer is fast, users will get the 
idea the whole map is faster.


Another thing is that in OpenLayers you can use tiled and untiled for 
your WMS server. Tiled means your mapwindow (+ an extra invisible 
border) is split in 9 pieces. These pieces are loaded sequential. 
Untiled means that a single image is retrieved from mapserver. You can 
mix the both. Say that you load the big topograhic map tiled and your 
own smaller datasets untiled. It will give a nice speedy feel. The extra 
border has the effect that when you pan half a mapwindow to the side, 
the data is already loaded. Again, another way to give user-experience a 
feeling of speed.

Can someone just help me understand how the postgresql database could
be queried for data within a specific date range? I am thinking that
the user could specify the dates in an initialisation page, and these
dates could then be stored at hidden CGI variables (or javascript
variables?). But if the data sources are specified in the mapfile, how
do I pass the dates to postgresql?
  

Date/Time functions for postgres are described here:


DATA "the_geom FROM (
  SELECT this, that, other, the_geom
  FROM my_daterange_table_with_geometry
  WHERE mydateColumnValue < %someDatefromOpenlayers% and 
mydateColumnValue > %someDatefromOpenlayers% - integer '30'

) AS foo USING UNIQUE id USING SRID=4326"

(Example on how to get a time-frame of 30 days around a given date.)

Sorry if my lack of knowledge is showing... Thanks again for the responses.

Tim Mashford.

Re: [mapserver-users] WFS and typename issue

[Milo van der Linden]

Have you tried using  ?

I had some sort of issue that looks like yours.

like this:

"gml_include_items" "MFIELD,KFIELD,DFIELD"
"gml_MFIELD_alias" "A Field for M"

I can retrieve fieldnames with spaces on my installation of mapserver 
for a WMS GetFeatureInfo request. If the same doesn't work on WFS I 
would suggest filing a bug.

Re: [MAPSERVER-USERS] Mapserver equivalent for .NET

[Milo van der Linden]

Two things are getting mixed up here:
- dotnetmap might be using mapserver without mentioning it
- Sharpmap is indeed using GDAL/OGR projnet and more but they are fully
open about it. Mapserver is NOT running beneath Sharpmap. SharpMap does
it's own map rendering.

Adam Hill schreef:

  I don't think it is actually using MapServer proper. Daniel was just
pulling our collective legs :)

They do have a Extension framework where they use
GDAL/OGR/Oracle/Postgis C# wrapper libraries extensively as data
providers. They also make use of the .NET port of JTS for spatial
operators and ProjNET, which is the port of Proj4.

They do have a client app demo of SharpMap here -
http://www.codeplex.com/Project/Download/FileDownload.aspx?ProjectName=SharpMap&DownloadId=24213
. And if someone from OSGeo/MS wants to stop buy and and ask for some

Re: [MAPSERVER-USERS] Mapserver equivalent for .NET

[Milo van der Linden]

Concerning SharpMap:
- I am writting a webservice handler for SharpMap at this moment. It 
allows SharpMap to behave as a WMS 1.3.0 server ONLY for the GetMap 
request (for more functionality; volunteers needed)
- For SharpMap I have written a XML specification that is also humbly 
(and offers far less possibilities for now :'(  ) based upon the 
Mapserver Mapfile


To me Mapserver is the mother of Open Source Maphosting!

That's correct, I was talking about MapDotNet, not SharpMap.

For those still in doubt, just look at the docs, there are screen

Actually, I browsed a bit and there are mentions of MapServer in a 
few places in the wiki (docs) and in the forums, so their use of 
MapServer is not completely secret.  :)

Re: [mapserver-users] lane presentation of highways

[Milo van der Linden]

Hello Martijn,

I am able to help you on this one.

There is no need to set a transparent line. It is a matter of defining
style based upon an attribute.
First you need a definition for a class item:

CLASSITEM 'DRIVING_DIRECTION'

Then you set up classes for the directions:

CLASS
   NAME 'FROM_LEFT'
     _expression_ 'FROM_LEFT'
     MINSCALE 0
     MAXSCALE 10
   STYLE
 SYMBOL 0 
 SIZE 6 
 OFFSET -3 0
 WIDTH 3
 COLOR 249 201 139
   END
    END

CLASS
   NAME 'FROM_RIGHT'
     _expression_ 'FROM_RIGHT'
     MINSCALE 0
     MAXSCALE 10
   STYLE
 SYMBOL 0 
 SIZE 6 
 OFFSET 3 0
 WIDTH 3
 COLOR 249 201 139
   END
    END

CLASS
   NAME 'SINGLELANE'
     _expression_ 'SINGLELANE'
     MINSCALE 0
     MAXSCALE 10
   STYLE
 SYMBOL 0 
 SIZE 6 
 #OFFSET 3 0 #NO OFFSET
 WIDTH 3
 COLOR 249 201 139
   END
    END

  If I have right understood,
you suggest to add the lines as an attribute/arrowsymbol to a single

Re: [mapserver-users] lane presentation of highways
  
  
I can't think of a way of doing this, because you physically need to
spread the two lines apart for the longer scale views if you want to
see both.  I have a couple of ideas about how to label a wide sigle
line though that would show both direction if they are attached as
attributes.
  
It might be possible to draw the lines, and then draw the layer again,
drawing only with the Symbols on top (no lines), and then offset the
arrow symbol locations,  Actually I think that would work.  I have
something similar in a address range labeling layer.  It would take a
bit of trial and error to do though.
  
You could still get into trouble though at longer range views, just
because there won't physically be enough room to apply the labels.

zoomed in a lot, you can always see the different driving directions

that each lane is colored depending the road condition. So, the

 The goal is to do this:
 When the user query the data via getfeatureinfo, I want to reload the

 With getfeatureinfo i could retrieve the ID of the selected feature,
 so I need to change dynamically the STYLE definition of my mafile, or
 something like this... any suggestion or a link to start reading docs
 on how to do this?
 Thanks :)
 Diego Guidi

  

In the mapfile, add a copy definition of the layer you want to highlight

LAYER
 NAME 'ps_highlight'
 TRANSPARENCY 100
 DUMP TRUE

   TYPE POLYGON
   DATA 'E:\mapdata\my_original_layer.shp'
   METADATA
 "ows_title" "ps_highlight"
 "ows_srs" "EPSG:4326"
   "gml_featureid" "id"
   END
   STATUS OFF
   PROJECTION
"init=epsg:4326"
   END
   MAXSCALE 10
   CLASSITEM 'ID'
   CLASS
  #NAME 'selection'
EXPRESSION "%id%"
  STYLE
SYMBOL 0
SIZE 6
  WIDTH 3
OUTLINECOLOR 255 0 0
ANTIALIAS TRUE
COLOR 255 0 0
  END
   END
END

And now call this layer with a WMS GetMap request where you add 
"&id=123" to the end of the request string.

[mapserver-users] tile server

Main purpose is to expand the usability of openstreetmap into the

You can't. OSM uses "Google" style tile indexes, OpenAerialMap has
support for "TMS" style tile indexes. GDAL only supports the latter. So
the answer is "patch GDAL".

Re: [mapserver-users] Problem creating WMS

[Milo van der Linden]

svGIS will return text/html only when the WMS server returns a message 
or error. The GetCapabilities is parsed correctly, but when the GetMap 
is triggered, it occasionally returns text/html on error.


The best thing to do is copy the request string from svGIS to your WMS 
server to a browser. If it is correct, you will see an image. If it is 
wrong, The browser will tell you it wants to download a file called 
"mapserv" or "mapserv.exe"
download and save it as "error.xml" then read the contents of the file 
and you will probably see an error message on why your WMS request fails.


Also note that in svGIS you must have a STYLES= element in your request 
and no Boundingbox or SRS should be there, they are added by svGIS 
automatically.


Is your server public? I can help you test it.

What I'm trying to set-up is a grid that is in GML file. And I want 
MapServer to build the layer reading the GML file and give it to 
OpenLayers (javascript API) would read it as WMS.


I have instaled MapServer in C#  so I'm using MapScript. Is this possible?

Thanks

Carlos

Re: [mapserver-users] Projection Issues

[Milo van der Linden]

The problem might be that in your mapserver proj4 implementation; the 
epsg:20355 is missing towgs84 parameters. These parameters tell 
mapserver the shift that is present between the wgs84 ellipsoid and the 
greenwich ellipsoid.


Could you check out the epsg file in your proj/nad directory; look up 
<20355> there and see if you have something like 
+towgs84=-70.9,-151.8,-41.4,0,0,0,0 default it says something like no_defs.

You can find a description on ellipsoid differences here:
http://www.remotesensing.org/proj/gen_parms.html

I looked up this somewhere on a mailinglist: ellps=aust_SA 
towgs84=-133,-48148,0,0,0,0


See if it can help you.

Good luck

Milo van der Linden

Re: [mapserver-users] clip and zip server

[Milo van der Linden]

Hello Jim,

This is no out of the box functionality, but I would solve this as follows:

You build some sort of webservice that responds to an AJAX request by:
A) //- Website functions ---//
1) - Taking the bounding box, the users e-mail and the selected layers 
as parameters

2) - Doing some business logic to tell if the request is valid
3) - Storing the request including the users e-mail and the boundingbox 
and the layers that the user selected (in a table in the postgres 
database for instance)

4)- return an AJAX response telling the user that:
   - His request is added to the que
   - He will recieve the dataset per e-mail

B) //- Server batch ---//
1) You build a script on the server that
   - looks at the postgres table for pending requests
   - loops the requested layers doing a geo-select (postGIS function)
   - Export the selection to shape using ogr2ogr or psql2shp
   - zip the shapes
   - mail them.

Hope this is helpfull for you.

Kind regards,

Milo

We have implemented  a mapserver site that allows users to create an
area of interest. Next, we want to let the user select some layers and
then clip the layers to the AOI, zip them, put the zip file on an ftp
server, and send an e-mail when they are ready. This should be done on a
second server from the main mapserver server.

Would appreciate any suggestions from anyone who has done something
similar or who has any ideas how this is best done. Original mapserver
site is in PHP and prefer that or Python for the second server.

Thanks,

Re: [mapserver-users] Dynamic Mapserver Technology

[Milo van der Linden]

[EMAIL PROTECTED] schreef:

Hi there,

one is seeing more and more flash-map sites on the web. It seems almost as if 
these are some kind of competition for the "real" IMS sites. Surely no real 
GIS application; but in many cases some basic information display is 
sufficient.
  
In my opinion: Commercially, the "real" GIS market is not at all as 
atractive as the "basic, more practical solutions" you see evolving all 
around us. GIS itself is often more an "in crowd" at local governments 
and large spatial companies, whereas businesses that need a map to 
enhance their business are often better of NOT having a real GIS and 
thus offer far better opportunities for openGIS companies and 
independent consultants. But this is my personal opinion.
So I wonder how far one can go with mapserver. Probably one has to use as 
well the flash-output option? And then, is there the possibility to 
dynamically highlight a country when the mouse is over that country? Display 
additional information - something like a country profile etc Everything 
within one single application, without the need to reload a page, another 
window etc.?
  
There is an excelent opensource Flash webclient available: 
www.flamingo-mc.org it's development was supported by the dutch 
government and I have had the opportunity to use flamingo-mc to push a 
GIS-like solution to a market currently unfamiliar with GIS and this 
offers promising commercial opportunities.


Basically, you configure Flamingo-mc to connect to WMS-servers. You can 
even enhance it by setting up mapserver as WFS to return feature info. 
For me this all operates with mapserver in the background, not returning 
SWF, but just "basic" png images.


If you want more details on the solution I set up, contact me directly 
and I can let you have a peek at what I created.


Kind regards,

Milo van der Linden

Thanks for any hints,

Re: [mapserver-users] Open Source solution to display PNG maps converted from SVG in a map viewer with labels and possibly tiles

[Milo van der Linden]

Even data that is not georeferenced has some sort of projection being it 
0,0 for the lower left corner and 600,600 for the upper right. So you 
should be able to put that in Mapserver with a self created projection 
(1). Problems arise when you want to combine your maps with for instance 
satellite imagery because in that case you will need transformations to 
do the matching, and for transformations you need parameters to convert 
one projection to another (2). A quick and dirty solution for (2) would 
be to create images and georeference them manually with a GIS. qGIS has 
a nice georeferencing plugin that will help you in that process.


As you state in (2) "Mapserver requires a mapfile like a SHP"; that 
assumption is wrong. A mapfile is a metafile and in that way more like 
a  mapinfo wor file (workspace, I don't know the equivalent for esri) 
which has the great possibility to create meta descriptions for layers 
of an (almost) unlimited amount of known GIS sources.


So, the most important think to ask yourself is:
- Am I going to combine my SVG data source with layers that are 
georeferenced?


Because then you have some extra work at hand, but using mapserver to 
host your data is always an option.


Kind regards,

Milo van der Linden


Jeremy Short wrote:
The original data is stored in SVG and it is not georeferenced.  It is 
a collection of hand-rendered maps in Inkscape, an SVG editor, with 
geographical measuring units like latitude or longitude.


We wanted to stay away from serving up SVG because Firefox supports 
SVG but not IE and we didn't want to force people to have to install a 
plugin. I tried the link (http://www.carto.net/williams/yosemite/) and 
it looks good but it looks like the plugin is needed for IE.


Any ideas for non-georeferenced SVG/PNG source files to serve up PNG 
files which can be used as a base layer for a map?  Can I even use a 
non-georeferenced SVG/PNG with Mapserver?


Andreas Neumann wrote:
So, if I understand you correctly, your original map data is stored 
in SVG files.


In that case you can use Apache Batik to render into georeferenced 
PNG files (if your SVG data is georeferenced). You can trigger this 
rasterization process whenever there was a change in the SVG data. 
This georeferenced raster data can be fed into UMN Mapserver for fast 
delivery. My guess is, while the quality of the Apache Batik 
rendering process is excellent, it won't be as fast as the UMN 
Mapserver, when delivering maps.


Alternatively, you can consider to serve the SVG data directly, 
without going through PNG files. You can also combine SVG with 
Postgis where the vector data is stored in Postgis and the SVG is 
generated on the fly. You can see an example of this approach at 
http://www.carto.net/williams/yosemite/ - for bigger SVG files it is 
certainly faster if you store your geodata in a spatial database and 
deliver customized extents, simplified versions and sub-selects 
appropriate to the chosen mapscale.


Hope this helps,
Andreas

My goal is to render an SVG image map to PNG to display on our

capability. We have many maps. I want to use an Open Source 
solution. Our web server is running Apache.


Additionally we want to add a "layer" of text labels which will not 
get bigger when we zoom in. Too, since we have large pictures so 
they don't degrade when one zooms in, we would like to explore the 
ability to send only "tiles" of the map picture if it's required.


What I have found thus far:

1. Using OpenLayers as a client gives us the ability to load a PNG 
file, pan, and zoom.


2. For the ability to add layers of text labels and transport tiles 
of data I explored the possiblity to use Mapserver. It appears 
Mapserver requires a map file like an SHP file as input and it will 
output a PNG. I would like to feed it as input a PNG file but I 
don't know if Mapserver is designed for this.


Looking further into this I see one can possibly use a tool like 
gvSIG or AB Viewer to translate a PNG to a SHP file but I want to 
automate the process without this extra step because people will be 
modifying the SVG file periodically.


There seems like there must be a better way to accomplish what I 
want which is to render PNG images in a client web browser with the 
ability to navigate within the map and to render text labels and 
transport tiles of information. Is there?

Sorry, I guess I did not clearly state my question(s)!
I knew MS4W stood for the installation of MapServer on a Windows computer.

What I should have asked was once I had a set up under MS4W, which of 
the files would/can I upload to an Apache web host? Or will I have to 
completely do a separate set of files for each OS?


I am hoping that the map files and other files I create on my home 
computer using MS4W will be able to uploaded to the web host running 
Apache.
- mapfiles, font- and symbol files and the data files (shp, dbf, tab, 
dat and so on) are the files you are talking about. You can indeed 
upload them to "A webserver capable of running mapserver", change the 
paths in the mapfile and you should be ok.


I would strongly suggesty you to put pressure on the board of directors 
and tell them map hosting is NOT the same as web hosting, it requires 
specifically prepped server(s). Make sure they are willing to create 
some budget before you start making promisses and sign up with the guys 
at hostgis.com (I know from experience they are willing to set up a test 
period and their support is excellent) 

It will save you frustration, tears and sweat and a lot of precious time 
and you might even be able to live up to the expectations of the people 
who asked you to put a map online without realizing that GIS and 
Cartography is a specialism people go to university for...

Re: [mapserver-users] Setting up a MAP file to use data on a network share [newbie I guess! :-) ]

[Milo van der Linden]

Hello Greg,

I think that it is the account that the IIS service runs in that needs 
to be allowed access to the network share. So either you have to 
reconfigure the IIS server to run as your user (which brings up a whole 
new set of trouble :-() or open the share to the local IIS service account.


Your trouble is windows only and mainly an authorization issue unrelated 
to mapserver.


See if you can get in touch with a good system Windows administrator to 
testdrive various settings.



If none of this works out, I know of ways to open up postGIS accross the 
windows network which might be a last resort.


Good luck!

I proceeded as follows

 - Using IIS on a Windoze box (yeah, yeah, grin) set up a virtual directory to 
a network share using a UNC path \\server\directory that I use all the time 
with ArcGIS, etc – called it wms_data

 - Added my credentials in the ‘Connect As’ in IIS

 - Used the explore in the IIS MMC and confirmed I could browse the data there

 - Confirmed that the directories had the relevant web access permissions

 - Charged the relevant line in my MAP file to → SHAPEPATH "/wms_data/"

 - Changed the layer’s data pointer to → DATA "subdirectory/sameshapefilename"


* When I now load the page it says it can’t find the layer’s data!  Ugh! *


Note that if I use a local (i.e., C:\...\...\) path for the data and in the MAP 
file it works just fine… Also, want to look at MrSIDs the same way, which again 
works just fine using a C:\ path…


Note that I know enough about IIS to be dangerous!   ☺

Re: [mapserver-users] How to test Mapserver!

[Milo van der Linden]

The thing would be that instead of addressing mapserver directly like:

http://yourserver/cgi-bin/mapserv?

You would use:

http://yourserver/myproxy.php?

Since the hard clients add all the parameters themselves, your php 
script could strip all the parameters and under water call:


http://localhost/cgi-bin/mapserv?

And in this loop, you would also use a small piece of php code to log to 
a file.


I am sorry I don't have a working example, but I think this would solve 
your trouble.
