Re: [mapserver-users] How to Remove Layer

[Tamas Szekeres]

Venkat,

I just wanted to mention that this topic have already been discussed with
the same suggestion a month ago, see:
http://n2.nabble.com/Remove-Layer-based-on-layer-Name-C--td1974078.html

However it haven't satisfied with your requirements at that time ;-)

Best regards,

Tamas

Re: [mapserver-users] mapserver 0-values problem

[Raivo Alla]

Hi again,

I have to add that this expression:
EXPRESSION ([way] >= 100 OR [way]<=0) worked fine when I
substituted those 0-values with -1.

As I mentioned before, expression like that
EXPRESSION ([way] >= 100 OR [way]<=0 OR [way] eq 0)
does'nt filter out rows that had 0 value on "way" field.

[mapserver-users] mapObj.getlayersdrawingorder

[Balázs Bámer]

Hi All,

I tried to call MapObj.getlayersdrawingorder() from PHP Mapscript
(ms4w 2.3.1 with MapServer 5.2.1, PHP 5.2.6). PHP script terminates.
Same result for MapObj.getLayersDrawingOrder() (the PDF description is
ambiguous about these names).

How it is called? Is it really usable? In the appropriate .dll file
both names appear.

Re: [mapserver-users] mapObj.getlayersdrawingorder

[Alan Boudreault]

Balázs Bámer,

Note that in PHP, all functions names are case INsensitive  but
variable are case sensitive weird but true ;)
So your call should work. Maybe you could try to execute "php -f
youFile.php" in console to see if php report errors.

Re: [mapserver-users] Unable to open file for writing in windows(plz immediate response)

[Dan Little]

Do you even have a "/opt" directory (and the related sub-paths in windows)? It 
just seems to be a very Linux construction.

Regardless, are you running Apache as a windows service?

Re: [mapserver-users] mapObj.getlayersdrawingorder

[Yewondwossen Assefa]

Hi there,

 You probably meant you did a call like this 
$oMap->getLayersDrawingOrder(), which is the correct syntax to use in php ?

Quick test using ms4w 2.3.1 environment returns expected result:

getLayersDrawingOrder());

?>

Jochen,

I would suggest you review:

  http://mapserver.org/development/rfc/ms-rfc-18.html


That seems like a rather complex solution and it falls short in several
aspects:
* Security should be the default, not some add-on
* It only protects passwords not the rest of the information.

Generally services should not leak any internal information to the outside
world. Passwords are only the worst case here. But anything like host
names, file names, database names, URLs auf cascaded WMSes etc. should
not ever get outside!

If there is an error this information should go into a log file. You can
output a time stamp or some kind of id in the error message so that you
can find the corresponding log messages. For servers only used
internally where you don't mind the information leak or for debugging of
a new setup there could be an option to output error messages to the
client. But thats would only be an option which is off by default.

See http://www.owasp.org/index.php/Top_10_2007-A6 for more on this.


Jochen,

Well, luckily we are an open community. Perhaps you would like to prepare
an RFC on a comprehensive solution and once approved begin work on an
implementation.  Be aware we are somewhat itchy about backward compatibility
on this project.

Re: [mapserver-users] google tiles

[Roger André]

Hi Chad,

I wasn't aware that "tile" is a valid mode of operation for Mapserver.  I
looked on http://mapserver.org/cgi/controls.html and didn't see it
referenced there, but its entirely possible that it exists and that I've
just missed it.  In any case, the way I'm familiar with generating google
map tiles is via the use of Tilecache.  Tilecache works as in intermediary
between Mapserver and your Google map. It make the appropriate request to
Mapserver for a tile, and then returns the tile to your map.  I think this
might be the solution you're looking for, http://tilecache.org/.

Best of luck,

Roger

[mapserver-users] missing colors with an xml color table

[Maciej Sieczka]

Hi!

There are missing colors when rendering a raster map with a
colortable stored in an xml file. Example:

I have an ESRI ASCII GRID with a colortable in xml (the files along with
a mapfile all attached as smp.tar.bz).

Rendering the raster in QGIS I get a picture as the attached
smp_qgis.png - which is OK.

Rendering it with MapServer the result is as in the attached smp_ms.png
- lacking the grey&black tones.

Why the difference? Could/should MapServer follow QGIS behaviour?


Using GDAL 1.6, MapServer 5.2.0 and QGIS 1.0 on Debian testing amd64.


The command to reproduce the smp_ms.png:

shp2img -e -4 20 36 61 -s 640 480 -m smp.map -o smp_ms.png

I wasn't aware that "tile" is a valid mode of operation for Mapserver.  I
looked on http://mapserver.org/cgi/controls.html and didn't see it
referenced there, but its entirely possible that it exists and that I've
just missed it.  In any case, the way I'm familiar with generating google
map tiles is via the use of Tilecache.  Tilecache works as in intermediary
between Mapserver and your Google map. It make the appropriate request to
Mapserver for a tile, and then returns the tile to your map.  I think this
might be the solution you're looking for, http://tilecache.org/.

Best of luck,

Roger

[mapserver-users] optimal path between two points.

[Valeria Muñoz]

Hi

 I would like to implement the service "optimum path between 2 points," can
someone help me to be able to implement it?. The general idea is that a user
picks a point A and point B and a display on the map the best route to get
from point A to B.

Valeria,

MapServer itself does not do route calculation.  You might find some
useful pointers on this page:

 http://wiki.osgeo.org/wiki/OpenRouter

I think the pgRouting (built on postgres/postgis) is the best bet for
integration with MapServer.

So you have various options depending on the client software you are 
using. So here are some ideas for you:


1) put the route into a results table with a unique id, and pass the 
unique id back to the client where it can then request the route image 
via a mapserver mapfile the connects to the postgis database and 
requests the layer be drawn with the unique id to select the appropriate 
route.


2) make an ajax request to generate the route and return the polyline as 
 an xml or json object back to the client. The client then parses the 
result document and displays the route over the map.


3) if you use OpenLayers for the client then you can use it to help you 
do 1) as an image, or 1) as a wfs layer, or 2) as a vector layer.


You can look at the source for my demo page 
http://imaptools.com/leaddog/routing/dd.html which does this with a 
modified version of pgRouting (pgRouting does not return turn-by-turn 
directions), but you should be able to modify my code to work with 
pgRouting. I wrote a simple php script to proxy the route request into 
postgres and to format the results back to the client.


Look this over and see how far you can get with this. If you get stuck, 
ask and I'm sure we can get you moving in the right direction.

Re: [mapserver-users] Is there a way to add a single click zoom button

[boesiii]

I added the script and the button control but I am not sure about the third
item you mentioned.  I added the lines "
" in the mapserver variables
section but when I click the button nothing happens?

What is the problem?

My favorite way of doing that is to use OpenLayers for my client side 
code. The JavaScript API have options for most anything you would want 
to do with a map. It support shift-click-drag out of the box to do 
rubberband zooms.

[mapserver-users] WFS Getfeature returning incorrect features

[Fong,Phil [Burlington]]

Hello,

I have a mapserver (5.2.1) setup that is returning incorrect features
from a WFS getfeature request. For example, if a bbox is specified:
bbox=-100,50,-99,51, then some point features outside of bbox get
returned. However, the overall bounding box of the features (in the
gml:boundedBy element) looks right and is inside the bbox, but is not
representative of the features that are returned (see below). Also, if I
try different bboxes, it would appear that it's always  taking the first
N (which varies) features in the layer (sites.1, sites.2 always appear).


What is going on and how to fix? Has anyone else encountered this odd
behaviour? The point features are stored in a database table (mssql to
be specific) and connection is using OGR (through ODBC). Mapserver is
running in Windows Server 2003 (64-bit).

Thanks for any help.

-Phil

Re: [mapserver-users] google tiles

[Roger André]

Fascinating, thanks for sending the link!  Since you state that you only get
blank images when you try it out, perhaps it is a projection mis-match? It
appears that your mapfile extents are defined in meters, which would match
spherical mercator, but your layer is in EPSG 4326.  What if you make your
extents be in lat/lon instead?

[mapserver-users] how to stop extent being visible?

[Greg Luker]

Hi mapservers,

Is there any way to stop the MapServer image extent being visible to 
the outside world? ie in cgi the imgext= is visible in the URL line, 
and in php-mapscript a simple View/Source in the browser will show 
the extent value. In my app it's important that the extent not be visible.


Thanks,
Greg.

You need to specify the PROJECTION of your LAYER.
