Hi,

This tile contains most part of the parcel. What might happen is that 
when the client is asking for the next tile to the left, then the BBOX 
is partially outside the EXTENT that you have configured for the layer. 
Maybe Mapserver considers that the request is off-site and does not 
render anything.
Make your extent bigger or comment it out altogether. Also check the 
extent at the MAP level. It should cover the whole area where you 
possibly have data.

Hi Jukka,

Thanks for your email. I got the extent from the geometry it self.
Like so:

ibm.food_forest -summary

   INFO: Open of `PG:host=px port=5432 dbname=px user=px'

Re: [MapServer-users] Looking for Examples of COMPOSITE

Can you use color and outline color at specified width? Such as:

   CLASS
  NAME 'state'
  EXPRESSION ("[rttyp]" eq "S")
  MAXSCALEDENOM 150
  STYLE
 COLOR '#ff'
 WIDTH 8
 OUTLINECOLOR '#0e3e09'
 OUTLINEWIDTH 2
  END
   END

You could also add transparency to your outline color.

Re: [MapServer-users] FlatGeobuf as output format

2023-06-21 Thread Scott

I'm not sure how you're creating your fgb's, but from an ogr2ogr context 
try promoting all geoms to multi:


-nlt PROMOTE_TO_MULTI

Hi!

I'm trying to integrate OGR's FlatGeobuf driver as an output format in 
my mapfiles.
It works for the most part and it's awesome, but it fails immediately 
when I feed some MultiPolygons into it.


The geometries are queried from an MSSQL DB.

I get the following error:
msOGRWriteShape(): OGR error. Attempt to write feature failed (code=6): 
ICreateFeature: Mismatched geometry type msCalculateScale(): General 
error message. Invalid image width or height.


I found a little note in the docs which corresponds with this issue 
(https://mapserver.org/input/vector/ogr.html 
):
/"Even though MapInfo and other OGR data sources may support layers with 
mixed geometry types (e.g. points, lines and polygons in the same file) 
this is not yet supported in MapServer. So you still have to define a 
layer ‘TYPE’ and make sure that all the shapes in the OGR data source 
are compatible with that layer type, otherwise MapServer may produce an 
error about incompatible geometry types at runtime."/

/
/
So it fails for me when I have Polygons and MultiPolygons in the table 
I'm querying.
But it also fails if it includes MultiPolygons only. So with no mixing 
of types.


I'm using the POLYGON type for my layer in the mapfile.

The same dataset works fine when I'm using the GML2 output format. Even 
with mixing Polygons and MultiPolygons.


Am I doing something wrong here?
Is it a known limitation for MultiPolygons?
Is there a way to bypass the issue while retaining the geometries in the DB?

Thank you

Re: [MapServer-users] What is the optimal value of requests per second for Mapserver?

2023-04-20 Thread Scott

Depending on what you're doing, any bulk requests should be to a 
pre-seeded MapCache and not the WMS server per se. In a production 
environment a modestly detailed raster, it's easy to kill a WMS server 
of any size.


You're going to have to test a range of requests to get a usable setup. 
You may even consider limiting the size of bounding box requests.

For example a simple raster wms will be able to do many request per second.

On the other side serve out osm from a postgis database will in some 
heavy scale not do more then 1 tile every 5 second


I would determ it based on cpu/disk usage instead of request  per second

Re: [MapServer-users] Multiple requests to s3 bucket to the same Tiff after GetMap request

2023-02-10 Thread Scott

That file appears to be a cloud optimized geotiff. If that's the case
multiple gets is perfectly normal as it's possibly retrieving overviews.

I don't see a server return code, but if it's 206, everything is fine.

Additionally, you can open your dev tools in your browser (Ctrl+Shift+I)
and watch how many bytes each request gets. With COG it should never be
the whole file.

Re: [MapServer-users] Failed to download capabilities:Download of capabilities failed: Connection on mapfile with more than 1000 layers

Yet another reason to put a wrapper around you mapserv binary.

I have hundreds of layers and block GetCapabilities outright and return 
a proper warning stating such.

Obviously, this is not a solution for everyone. Adding this, some 
security traps and whatever else you need to your wrapper is really 
beneficial.

The time is not a constant (number of layers * x milliseconds). For
example, it is faster to generate the layer BoundingBox into
GetCapabilities if the wms_extent metadata is set for the layer

 but how much faster it is depends on the data source.

GetCap with that many layers?

I am also interested in what purpose you are using the WMS with this

Re: [MapServer-users] How do I use an SQL query in a Postgis tileindex of vector files?

2022-12-06 Thread Scott


Your connectiontype is ogr, you need postgis for a query


CONNECTIONTYPE POSTGIS

Hi,

How do I get a tileindex of vector files working from data in a Postgis 
database and accessed via an SQL query of my choosing?


I would like to make a vector tile index as described at 
https://mapserver.org/optimization/vector.html#index-your-data 
 using 
data stored in a Postgis database and a SQL query of my choosing.  Here 
is one approach that works:


1.  create a test table in postgres database:
      > create table testtable (id int, location text, geom 
geometry(Polygon,4326));


2.  insert data into the table:

      insert into testtable (id, location, geom) values (1, 
'/test_data/test.geojson,0', 'POLYGON((122.0137747521 
29.96355712017804,122.01424752183958 
29.915620560607106,122.06927507957919 
29.91602043815968,122.0688286928125 
29.963957768165944,122.0137747521 29.96355712017804))'::geometry);


3. Define a layer using the OGR connection:

LAYER
   NAME "vector"
   TYPE POLYGON
   CONNECTIONTYPE OGR
   CONNECTION "PG:\"host=localhost user=postgres dbname=mydatabase 
password=mypwd tables=testtable(geom)\""

   STATUS OFF
   CLASS
     STYLE
       WIDTH 1
       OUTLINECOLOR 255 105 180
     END
   END
END

4. Issue a request:

     mapserv 
QUERY_STRING='SERVICE=WMS=/tmpp/mapfile.map=1.3.0=GetMap=image/png=vector=256=256=EPSG:3857=13580108.193257555,3487974.474709164,13585000.163067807,3492866.4445194146'


and I get an image of my vectors back.

How do I use a more complex query than `testtable(geom)`?  I tried 
specifying a query via a DATA block:


LAYER
     NAME "vector"
     TYPE POLYGON
     CONNECTIONTYPE OGR
     CONNECTION "PG:\"host=localhost user=postgres dbname=mydatabase 
password=mypwd\""

     DATA "geom FROM (SELECT
         id,
         geom,
         location
       FROM testtable
     ) AS subquery USING unique id USING SRID=4326"
     PROJECTION
       "init=epsg:4326"
     END
     STATUS OFF
     CLASS
       STYLE
         WIDTH 1
         OUTLINECOLOR 255 105 180
       END
     END
   END

However, the same query generates an error:

mapserv 
QUERY_STRING='SERVICE=WMS=/tmpp/mapfile.map=1.3.0=GetMap=image/png=vector=256=256=EPSG:3857=13580108.193257555,3487974.474709164,13585000.163067807,3492866.4445194146'


"msOGRFileOpen(): OGR error. Open failed for OGR connection in layer 
`vector'.  File not found or unsupported format. Check server logs.

msDrawMap(): Image handling error. Failed to draw layer named 'vector'"

I tried using a postgis connectiontype, but could not get that working 
either

Re: [MapServer-users] Fwd: Setting up authorization for Mapserver access using Apache2 .htaccess

2022-11-16 Thread Scott

Another way is to put a wrapper around your mapserv binary. I use PHP,
call my wrapper 'reflect' then let apache know to use PHP on 'reflect'.
Note the lack of .php extension. If you did have the extension no extra
modifications to apache conf would be required.

This has huge benefits. The single biggest advantage is I can use a
non-standard WMS uri, ie, pass only a width or height then calculate the
missing dimension from bbox. This always results in a perfect aspect
ratio for the resulting image. (Yes, GeoServer uses the name 'reflect',
too. No accident).

I also use it for security screening. 'GetCapabilities' has also been
intercepted and largely disabled.

I am running a website with Apache/2.4.53 (Debian) and Mapserver 7.6.2.
I have set up a 'secure' part of the web site following instructions
here:
https://www.digitalocean.com/community/tutorials/how-to-set-up-password-authentication-with-apache-on-ubuntu-14-04 .

I would now like to display some geospatial data held in Mapserver via
an Openlayers WFS map on the secure site. The challenge I have is that
once a user logs in, they can see the MapServer access details in the
Openlayers script so have the server URL and mapfile name, and can
access this outside the secure site i.e. without going through Apache
authentication.

There was some discussion about securing access MapServer 11 years ago
(https://gis.stackexchange.com/questions/5686/securing-wms-against-unauthorized-access ) but this didn't seem applicable.

As I understand it Mapserver is accessed through a CGI to which requests
are redirected through Apache. Would moving the /usr/bin/mapserv
executable into a folder managed by Apache2 work? (as seems to be
suggested here:
https://stackoverflow.com/questions/51850322/cgi-bin-htaccess-or-apache2-config-rules-bring-up-password-dialog-but-cgi-exec

Re: [MapServer-users] "Emergency" map server on Raspberry Pi - raster/PNG source in folder structure

2022-10-12 Thread Scott

This is an ideal scenario for serverless.

Put your vector data in FlatGeoBuf (.fgb) format and your highest res
tiles as a COG tif. You can have those files on a local device or in the
cloud.

Use leaflet with flatgeobuf, georaster-layer-for-leaflet and some modest
javascript.

You're making this wy too difficult.

Topographical (and other) maps of whole Finland are available under CC4

The data can by rsync'd down.
I'm not clear how I would configure mapserver for that. Do I have to
create one map with extent and such for each PNG tile or can I point
mapserver to the root directory of the data and tell it to go through
it recursively and get the data from the PGW sidecar files?

Re: [MapServer-users] WMS: Not all features show, depending on how I zoom and pan

2022-10-02 Thread Scott

It would be interesting if you could change your
'irrigation-network.gml' into a different format, say .shp, something like:

ogr2ogr irrigation-network.shp irrigation-network.gml

Then try that as a data source in your layer and see if your results
differ. This would might help us distinguish between a driver issue and
a mapserver issue.

Hello Seth,

Thanks for replying. I experimented and found out there's no difference
if I use something minimal such as what you suggested. What does make a
difference is the CRS: if I tell QGIS to use EPSG:2100 (Greek grid—the
CRS the data files use), then everything works fine. If I use 4326 or
3857, then the problem appears. Therefore it appears that the problem is
with reprojecting (as the stackexchange user "nmtoken" had suspected).
Leaflet seems to be requesting 3857.

What would be the right course of action here? Should I tell Leaflet to
do the reprojection instead? Should I investigate further why mapserver
has trouble reprojecting (and how would I do that)? Should I reproject
my data files (GML) offline and store them in 3857 instead of 2100? Is
there any common/best practice regarding this?

Thanks!

Re: [MapServer-users] MB Tiles vs. UTF grids

2022-09-02 Thread Scott


I'm ill equipped to answer your question directly.

However, as you delve into the world of vector tiles I'd strongly 
suggest taking a look a FlatGeoBuf (.fgb). It's an index format 
supported by GDAL and MapServer. It's very fast and painless.


The home page has demo's for openlayers, leaflet and mapbox, using a 
single 12GB census data file. Leaflet seems to be the most responsive.

Note that I am trying to stay outside the Mapbox empire (as much as

GDAL can produce MB tiles (but not sure if that includes UTF grid info

Would anyone have some insights ?

Re: [MapServer-users] Ask for advice on Caching large layers on high zoom level

2022-09-02 Thread Scott

COG files imply that they are already tiled. I'd be curious as to the 
performance of map rendering using just the COG files without creating 
tiles.


Being the 'size of Poland' doesn't really matter. It's the pixel 
resolution that is important. If the pixel resolution is 100 meters vs 3 
meters you will have different performance results.


Seeding will always be bound by CPU, memory, etc. Creating an image 
(ami) of your system in AWS, then running multiple EC2's instance can be 
insanely fast.

Re: [mapserver-users] getting the scale in a map file at runtime

2022-06-04 Thread Scott

If you're using an SQL query in your map file and it's a WMS/WFS (maybe 
others) service, you can determine scale from !BOX!, %WIDTH%, %HEIGHT%.


To add to your question, I'd be curious to know does a resource exist 
that lists all '[var]' resources available to a map file at run time?

Perhaps you can use scaletoken? It's not the same as you are searching

scales.


Yes - I had not thought of that. It might be a better way than what I

Re: [mapserver-users] mapserver OGR does not forward BBOX at all

2022-03-29 Thread Scott

In your request you have a typeName=tiger:tigerRoads. In your map file 
the wfs_typename is GROUND_REFERENCE_VALUES_NI_int

Hi,
thank you for the fast reply. Unfortunately, even with the srs given 
with the bbox the "Fetch" command does not forward any bbox at all. So 
mapserver / OGR fetches up to the max number of features given no matter

the original bbox because they do not fit (just the first 500 or so).

Hi Lars,

Might this help?

geoserver - WFS and WMS query SRS parameter and BBOX usage - 
Geographic Information Systems Stack Exchange 



I haven’t done much with the WFS tech but based on the link above, you 
may need to provide the crs info for the bbox.


In their example:

http://demo.geo-solutions.it/geoserver/tiger/ows?service=WFS=1.1.0=GetFeature=tiger:tiger_roads=EPSG:3857=40.7,-74,40.8,-73,urn:ogc:def:crs:EPSG:4326=1 



Note the bbox is defined as:
bbox=40.7,-74,40.8,-73,urn:ogc:def:crs:EPSG:4326


If your bbox is the same as the requested projection:
your bbox in the wfs request would be:

BBOX=545592,5806696,548144,5810131,urn:ogc:def:crs: EPSG:25832

Or the epsg code at the end would be whatever units your bbox is in.
Note, the bbox EPSG code can be different than the srsName

*Subject:* [mapserver-users] mapserver OGR does not forward BBOX at all

Hi All,

First of all, thank you for your support and great work on Mapserver!

I have a strange issue using either OGR WFS driver on Mapserver 
7.6.4-1 or ogrinfo (GDAL 3.0.4, released 2020/01/28) on Ubuntu 20.


When I call on a particular public server, mapserver / gdal / ogr does 
not seem to forward the bbox. I had a similar issue before (over a 
year ago) on another server but this was fixed by an update in GDAL it 
seemed.


The Server is

`https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?`

The Layer is
`boris:BR_BodenrichtwertZonal`

A direct call from the browser works:

`https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS=2.0.0=GetFeature=EPSG:25832=545592,5806696,548144,5810131=boris:BR_BodenrichtwertZonal 
`


I can see in Mapserver log (CONFIG "CPL_DEBUG" "ON"  CONFIG 
"PROJ_DEBUG" "ON") that the BBOX is missing:


`Fetch(https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS=1.1.0=500=EPSG:25832_CAPABILITIES_BOUNDS=YES=GetFeature=boris:BR_BodenrichtwertZonal 
)`


By the way, it does not matter if WFS 1.1.0 or 2.0.0 are used.

Trying with ogrinfo:
```
ogrinfo -ro -spat 545592 5806696 548144 5810131 
WFS:"https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022;

Re: [mapserver-users] Fwd: Why TileMode generates different display effect of WMS with the same map file?

Re: [mapserver-users] Point query from Mapserver raster

2021-10-29 Thread Scott

If you're using postgres/postgis it's easy using the raster version of 
st_intersection. It returns lat/lon/value or more precisely 
geometry/value. See more here:


https://postgis.net/docs/RT_ST_Intersection.html

Then it's just WFS.

Hi,
Now that I have my WMS and WCS servers working well (thanks, list!!), I 
have one more thing I would like to figure out how to do.


I want to do point queries on [Lat,Lon] points for their elevation from 
the terrain layer I have.


I have done some searching and come across various ideas such as Raster 
Query (https://mapserver.org/input/raster.html#raster-query 
) and a query 
template  
(https://gis.stackexchange.com/questions/167239/mapserver-raster-picking-elevation-data 
) 
but haven't found enough information for either to implement it.


I came up with a solution that works fine, but might be considered as 
going "All Around the Barn"   What works is to add an ASCII output 
format to my map file that serves terrain like this:


OUTPUTFORMAT
NAME XYZ
DRIVER "GDAL/XYZ"
MIMETYPE "text/plain"
IMAGEMODE FLOAT32
EXTENSION "txt"
END

and then use GetCoverage on a small rectangle whose lower-left corner
is the point whose elevation I want:

http://localhost:8080/wcs?SERVICE=WCS=2.0.1=GetCoverage=SRTM_3_arc-second_grid=XYZ=Lat(42.948,42.958)=Lon(-122.086,-122.076) 



and then take the first line of the returned output file.

What would Mapserver best practice be for a problem like this?

Thanks very much,

carl

Re: [mapserver-users] Getting started with mapcache for WMTS...

2021-10-25 Thread Scott

Try using mapcache seeder. That will create some cached images to work 
with. It will also test your mapcache config:


https://mapserver.org/mapcache/seed.html

How you use those tiles is a whole different subject.

Hi again,

Is there a way to search through the mapserver-users mailing list 
archive except month-by-month?  If so, I can't find it.  (I usually use 
my Gmail archives for GDAL and PROJ since I've subscribed forever to 
those but I'm a mapserver newbie.)  Anyway...


I am trying to configure mapcache to serve from my (local and AFAICT 
fully working) WMS server on my MS4W 4.0.5 installation.  I am following 
the  directions at https://mapserver.org/mapcache/index.html 
 as well as the steps listed 
from the local MS4W page (#mapcache-apache-module).


I think I understand the basic principles and have added a new source 
that looks like this:





image/geotiff
FAA_Sectional_Charts
TRUE
EPSG:4326
-125,24,-61,49



http://localhost:8080/wms 



and a new tileset that looks like this:


faa
disk
WGS84
PNG
5 5
10
3600

(This is the same as the "test" tileset with a different source.)

But how do I test this? The query

http://localhost:8080/mapcache/wmts?service=wmts=getcapabilities=1.0.0 



lists my new source as a layer. The docs say

 5.

Test your MapCache configuration by following steps in the
associated MapCache testing docs


but that seems to be about testing the mapcache/demo.  I don't see how 
to add something to the mapcache/demo if that's possible.  What am I 
overlooking?


Thanks a lot,

Presumably you could use an OGR layer although I've not done it myself.

Re: [mapserver-users] MAXSCALEDENOM using runtime var

2020-06-16 Thread Scott


Thanks for the response.

My mapserv binary is in a wrapper so I have control over dubious 
features I may (intentionally) introduce.


With that said, if it's not readily available and only available via 
modification, someone more knowledgeable had good reason. I'll think of 
a different approach.


Thanks again!

Hi Scott: Nope, the various scale denominator properties are not mutable

(just modify maplexer.l (look for the keyword of choice) and rebuild) 
but I'm not sure it's a great idea since you could be opening up some 
performance headaches for both your mapping box and backend data 
sources. I mean, a user could essentially affect at what level high 
density data could be drawn at, so imagine asking for high density roads 
at a global scale from a remote PostgreSQL/PostGIS source.

[mapserver-users] SVG relative points

2018-10-02 Thread Scott

Is there a mapfile configuration option for specifying how the output 
svg geometry is created? Specifically, relative geometry instead of 
absolute.


For instance, to get relative geometry using postgis I can do this:

st_assvg(geom, 1, 0)

...which says output geom, in relative geometry (1) and number of 
decimal places(0).


Relative geometry and no decimal places (ie, epsg 3857, meters) reduces 
the resulting svg significantly.


Your thoughts?

Re: [mapserver-users] Server hacked via cgi-bin - Mapserver, PHP, …? How to better protect the machine now?

2013-12-09 Thread Scott

If I understand you correctly, you have the php executable in cgi-bin? 
That is a major no, no. You should never do that, be it the php binary 
or the perl binary as an attacker can pass command line parameters 
directly to the executable bypassing your configuration file.


Only scripts like *.pl or *.php, which call the binary on the first line 
ie, #!/usr/bin/php -q, should be placed in the cgi-bin directory.


As far as mapserve in cgi-bin, I don't know enough about it. Personally, 
I would never put *any* executable in cgi-bin, including mapserv.

Hi there,

our server on which we have an application with mapserver running has been

Now, not yet 100% how they came in… But it seems they came in via PHP in 
/cgi-bin/. But we're not 100% sure. If it would be the case, we could delete

Thanks for any hints,

[mapserver-users] Lat/Lon variable? Vertical GRID labels?

2013-11-06 Thread Scott


Greetings!

Newbie here. I've been working with the excellent map server program for 
about 2 weeks. It is awesome.


2 questions (for now):

Are variables for lat/lon sent to a layer, ie, [lat] or [lon] so that 
they may be used in EXPRESSION?


How do you make vertical lat, left edge, labels for the GRID. I just 
can't figure that out.


Thanks!

[mapserver-users] GetLegendGraphic and Mapserver upgrade

2011-04-01 Thread Scott Stewart

Hi

I recently upgraded a mapserver 5.2 server to 5.6.6 and it has broken my
abiltity to get legend icons WITHOUT labels and a specificied size

here is my legend block from my mapfile

LEGEND

  END


and here is my RULE for the layer

 CLASS
  NAME AboveNet
  STYLE
ANGLE 360
COLOR 0 0 255
OPACITY 100
SYMBOL 0
WIDTH 4
  END
END

 and here is my request

http://

When I make this call on the new server, I ALWAY get back a legend graphic
with a label. On the old server, i get back a nice 16x16 png. I have read in
some place about ommiting the RULE in the request, but this didnt work for
me. It still returns the label. If i remove the CLASS from the mapfile, it
returns an empty image

My question is what changed and how do i go about fixing or rectifying the
problem?

[mapserver-users] Changing map file parameters via a URL - special characters

2010-08-11 Thread Scott Pezanowski


Hi,

I am trying to use mapserver to generate image maps from a PostGIS connection 
based upon a user entered FILTER. The data column I am trying to filter by is a 
tsvector column type. So the FILTER for my LAYER looks something like this:

FILTER textsearchable_index_col @@ to_tsquery('search terms')

I do have things working where I can hard code the FILTER for the LAYER in the 
MAP file. Things work great and I am very happy about this. The problem lies 
that I would now like to allow my client application to change this FILTER 
dynamically through a URL request based upon what search terms the user enters. 
So the URL would look something like this:

http://.../mapserv?map.layer[layername].filter=%22textsearchable_index_col%20@@%20to_tsquery%28%27newsearchterms%27%29%22mode=mapmap=mapfile.maplayers=layernamemap_imagetype=pngmapext=-73203436.227488+-51717904.824712+73203436.227488+51717904.824712imgext=-73203436.227488+-51717904.824712+73203436.227488+51717904.824712map_size=1870+1321imgx=935imgy=660.5imgxy=1870+1321

I am getting the following error:

loadLayer(): Unknown identifier. Parsing error near (textsearchable_index_col 
@@ to_tsquery('newsearchterms')):(line 1)


Through looking around a little, I believe the @@ special characters in the 
filter parameter are causing the issue. Can anyone confirm that this is may be 
the case (or think of what else may be the issue) and suggest a workaround 
(escaping these characters in some way, etc.)?

Thanks,
Scott

[mapserver-users] RE: Changing map file parameters via a URL - special characters

2010-08-11 Thread Scott Pezanowski


Hi,

I have looked into this more and it may not be the special characters. I can 
not change the filter in any way using this url parameter method. The only url 
filter parameter that works is an empty one:

mapserv?map.layer[0].filter=''

If I add any filter into the single quotes (even a very simple one), then I get 
this error:

mapserv?map.layer[0].filter='oid=5'

loadLayer(): Unknown identifier. Parsing error near (oid=5):(line 1)


Does anyone know the correct syntax for this parameter? I am going but this 
document page:

http://mapserver.org/cgi/controls.html

In this section:

Changing map file parameters via a form or a URL

[mapserver-users] SUA convert

2009-11-09 Thread Scott Penrose


Hey team

I am using Mapserver to show some airspace, and the data comes in a  
standard format called SUA or OpenAir. Both a basic text files using  
LatLong and descriptives shapes, such as:


TYPE=CTA/CTR
TITLE=ADELAIDE
TOPS=FL245
BASE=FL180
POINT=S353001 E1364920
POINT=S351526 E1373454
POINT=S351526 E1373454
ANTI-CLOCKWISE RADIUS=49.97 CENTRE=S345649 E1383128 TO=S354540 E1381803
POINT=S354540 E1381803
POINT=S362422 E1380512
POINT=S362422 E1380512
ANTI-CLOCKWISE RADIUS=89.95 CENTRE=S345649 E1383128 TO=S353001 E1364920

What would be the best (probably read here - easiest) way to display  
the data on mapserver?
Which probably translates to - what is the easiest file format or  
tools to use to convert and display the data above?


E.g. I could write some Perl/XSL to convert the files into KML - but  
is that the right format? Perhaps shape files?


Or... hope above hope... maybe someone has done this already? or knows  
another way to show Airspace files?


Thanks

RE: [mapserver-users] symbolize a wms map based upon a sql count() query

2008-10-30 Thread Scott Pezanowski

Hi Pietro,

Thank you for your response. Sure, I will try below to add some sample data 
that illustrates what I am trying to do. I have a votes table which has a 
vote for each county (A versus B). This can be joined by a responseid to a 
table response, which has the date in which the votes were submitted. Also, 
countyid references my geometry in a separate table. In summary, the first 
thing I would like to do is count the number of votes for 'A', and count the 
number of votes for 'B', both per county and based upon a user entered 
datesubmitted range; And then symbolize my map based upon these results. Also, 
and I guess ideally, I'd like to also produce a percentage of votes for 'A', 
per county, based upon the total votes for A and B for each county. And then 
color code my counties based upon this percentage.

Thank you for help you may provide.

Scott

[mapserver-users] symbolize a wms map based upon a sql count() query

2008-10-29 Thread Scott Pezanowski

Hi,

I am hoping to be able to symbolize a WMS or image map, based upon the results 
of a SQL COUNT() query. To be more specific, this query needs to be dynamic 
based upon user input from my application for specific attributes in the data, 
count up the number of records that meet that query, and then produce a 
choropleth map of the resulting counts. So the query would produce, a count of 
10 records for one county, 5 records for another county, etc. and my counties 
will be colored based upon a scheme for these counts. My data is in a PostGIS 
database.

Is there a way to do this with Mapserver? I am currently simply returning all 
of the records that meet my criteria and counting things up on the client 
application. But I am hoping there is a way to do this on the server or 
database-side of things.

Thank you very much in advance for any help or tips you may be able to offer. 
Also, please let me know if you need more info on what I am trying to do.

Thanks,
Scott

[mapserver-users] Mapserver equivalent for .NET

2008-03-05 Thread Scott Ellington

Hi,

I currently work at ISC and was asked to respond on this thread.

A few notes on some comments:

That being said, I can still wish that they be more open and give
credit 
to MapServer for providing the core of their system, or perhaps spend 
some time on this list helping users, or do something/anhything for the 
project... for me it's a wish, not a requirement. --Daniel Morissette

Howard Butler brought up a lot of these issues a while back.  In terms of 
openness, I can honestly tell you that there is no intent to hide the fact
that mapserver does the map rendering in MDNS.  I am not a sales guy, but
I have been told that there are some local governments that don't want to
hear that you are using open source, so it's just not something that is pushed.

There have been some contributions however.  Howard would be the person to list 
all these out.  But I know that someone here wrote the MS SQL Server 2008 
plugin.

this definitely sounds interesting.
Are they using the mapscript api or are they going via CGI?
How are exactly using mapserver? (I wish i could see this by myself, but
looks at their site that there is not a downloadable demo of it)  --Paolo Corti

MDNS uses mapscript/C# to render maps.  It has a Common .NET API that if you 
notice 
has many mapserver-isms.  All of the querying/editing is done within MDNS 
however.  Also, you 
should be able to download a demo if you log in.

and the mapfile docs themselves are awfully familiar.  --Daniel Morissette

The mapfile reference page is directly copied from the mapserver site.  
I included the license at the bottom that I found on the website.
Let me know if I am missing something.

The MapFile format used in MDNS adheres to the MapServer map file 
specification.  I didn't know that our good ol' mapfile was such a universal 
reference !
But, althought funny, this sentence tries to make people believe 
MapDotNet only use the mapfile format, and not mapserver itself, which 
can be considered unfaithfull if it effectively uses the mapserver 
engine behind.  --Guillaume Sueur

I wrote that.  I didn't mean to imply anything, but MDNS does use the mapFile 
outside of map
rendering.  However, I changed it to: 

MapDotNet Server currently uses MapServer 5.0 to render maps, and relies on 
its mapFile format.
