Re: [mapserver-users] queryByAttributes on PostGIS-Layer
Found the problem (thanks to Nicol ;-)
Code:
@$myQuery = $layer-queryByAttributes('nr_','7', MS_SINGLE);
must be changed to:
@$myQuery = $layer-queryByAttributes('nr_','nr_=7', MS_SINGLE);
Is this a bug?

Subject: [mapserver-users] queryByAttributes on PostGIS-Layer
Hallo list,
My test-system: Mapserver 5.02 on WinXP and postgreSQL 8.2
I try to make some querys via php-mapscript for a postgis-layer:
queryByPoint,queryByShape and queryByRect is no problem.
queryByAttributes always return no result (field 'nr_' is an integer)
If I use a shapefile for the same data (biogasanlagen.shp)
queryByAttributes works fine.
mapfile:
...
LAYER
NAME biogasanlagen
TYPE point
STATUS on
CONNECTIONTYPE postgis
CONNECTION user=postgres password=xyz dbname=mydb host=localhost
port=5432
DATA the_geom from biogasanlagen using unique gid
#DATA biogasanlagen.shp
TEMPLATE void
CLASS
Name biogasanlagen
OUTLINECOLOR 128 70 0
COLOR 230 70 0
SYMBOL 'circle'
SIZE 12
END # CLASS
TRANSPARENCY 88
TOLERANCE 8
END
...
php-Code:
...
$layer = $map-getLayerByName(biogasanlagen);
@$myQuery = $layer-queryByAttributes('nr_','7', MS_SINGLE);
...
any idea?
Thanks Sven

Re: [MAPSERVER-USERS] Displaying population density with Mapserver
Hi David, I tried WGS84 yesterday after a little research on projection, but it didn't change anything. I tried re-generating the shapefile with WGS84 projection but it's still the same. In fact, my data comes from GPW v3 ( http://sedac.ciesin.columbia.edu/gpw/global.jsp) but I didn't find any clue on the projection used, I suppose there is none as you say. When you speak about translating ground units, do you mean I have to translate my shapefile from degrees to, say, kilometers before I can use SIZEUNITS kilometers ? I thought it could be done dynamically by MapServer. I found a tutorial about this, I will try it anyway (assuming my data is WGS84) and give you the outcome :) I attached my mapfile this time, just in case I made a noob mistake somewhere... thank you very much ! Faldor 2008/5/28 Fawcett, David [EMAIL PROTECTED]: Faldor, When you have point coordinates stored in a text file, there really is no way to encode/attach the projection definition. Even if you could, it doesn't sound like you really know what spatial reference system (SRS) or projection that it is in. The key to projecting to another SRS or translating ground units to another measure (from degrees to meters) is knowing what the current SRS of the data is. Since your data is worldwide and it is unprojected (lat/lon), a good first guess would be to assume that it is unprojected with using the WGS84.

Regards 2008/5/27 Fawcett, David [EMAIL PROTECTED]: Before you create lots of different layers to simulate symbol scaling, you may want to try something else. It has been a long time since I have played with scaled symbols, but give it a try. You should be able to scale the symbols by setting a SYMBOLSCALE in the LAYER object. This is the scale at which you want the symbol to appear at the SIZE stated in the map file. You may want to modify STYLE MAXSIZE if you think that you will want your symbols to be larger than 50 pixels. Another completely different approach that just came to my mind would be to use ground units (e.g. meters) to set the size of your symbol. To do this, set LAYER SIZEUNITS to meters. Calculate the size of a symbol in meters on the ground that will touch adjacent symbols, or give you the desired amount of space between the symbols. That way, the symbols should scale consistently.

[mapserver-users] Accessing raster cell values
Hello List, This question may be a general newbie GIS question and not solely related to Mapserver, so apologies if I'm posting to the wrong place.

Re: [mapserver-users] Accessing raster cell values
Hi,
if you have access to the mapfile, you can make a queryByPoint with
mapscript (i.e with an ajax-function)
You have to send your point-coordinats to the script like this:
$coord = split(',',$_POST[coord]);
dl('php_mapscript.dll');
//load mapfile
$map= ms_newMapObj($mapfilepath.'\yourmap.map');
//create point
$qPoint = ms_newPointObj();
$qPoint-setXY($coord[0]*1,$coord[1]*1);
//set layer
$layer = $map-getLayerByName(your_rasterlayer);
//Pointquery (Single)
@$datQuery = $layer-queryByPoint($qPoint, MS_SINGLE, 1);
//if success
if ($datQuery == MS_SUCCESS) {
for ($j=0; $j$layer-getNumResults(); $j++) {
$result = $layer-getResult($j);
$layer-open();
$shpobj = $layer-getShape($result-tileindex,$result-shapeindex);
$attr = $shpobj-values;
//echo round($attr[value_0],2);
$rasterdata = round($attr[value_0],1);
print 'My Data: '.$rasterdata.';
$shpobj-free();
}
}
else{
print 'no Data';
}

In fact, my data comes from GPW v3 ( http://sedac.ciesin.columbia.edu/gpw/global.jsp) but I didn't find any clue on the projection used, I suppose there is none as you say. When you speak about translating ground units, do you mean I have to translate my shapefile from degrees to, say, kilometers before I can use SIZEUNITS kilometers ? I thought it could be done dynamically by MapServer. I found a tutorial about this, I will try it anyway (assuming my data is WGS84) and give you the outcome :) I attached my mapfile this time, just in case I made a noob mistake somewhere... thank you very much ! Faldor 2008/5/28 Fawcett, David [EMAIL PROTECTED]: Faldor, When you have point coordinates stored in a text file, there really is no way to encode/attach the projection definition. Even if you could, it doesn't sound like you really know what spatial reference system (SRS) or projection that it is in. The key to projecting to another SRS or translating ground units to another measure (from degrees to meters) is knowing what the current SRS of the data is. Since your data is worldwide and it is unprojected (lat/lon), a good first guess would be to assume that it is unprojected with using the WGS84. Try defining your layer projection by including this block in your layer definition. PROJECTION init=epsg:4326 END David. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pierre-Benoit Besse Sent: Wednesday, May 28, 2008 4:11 AM To: Fawcett, David Cc: mapserver-users@lists.osgeo.org Subject: Re: [MAPSERVER-USERS] Displaying population density with Mapserver Well, I confess, I'm new to GIS applications and I do not know a lot about projections. I understand I have to tell MapServer what is the projection of each layer I use in the mapfile, but using ogrinfo on my shapefiles tells me that : Layer name: pop_density Geometry: Point Feature Count: 249937 Extent: (-180.00, -56.00) - (179.75, 83.50) Layer SRS WKT: (unknown) latitude: Real (24.15) longitude: Real (24.15) densite: Real (24.15) I generated this shapefile from a CSV file with 3 columns : latitude, longitude, density_value. Did I have to define a projection then ? How do I do that ? Best regards, Faldor 2008/5/27 Fawcett, David [EMAIL PROTECTED]: Have you defined an output projection for your map and input projections for each of your layers? It is likely that MapServer needs to know what the input projection/SRS is before it can translate to different units.

But I just tried the ground units stuff, I tried with a 50 kilometers wide square and it drew squares the size of ASIA !! oO I had to define a 1 feet wide square to obtain something more or less ok... Does anybody know why ? Aside from that It seems to work, thank you ! I will try the scalesymbol stuff tomorrow. Regards 2008/5/27 Fawcett, David [EMAIL PROTECTED]: Before you create lots of different layers to simulate symbol scaling, you may want to try something else. It has been a long time since I have played with scaled symbols, but give it a try. You should be able to scale the symbols by setting a SYMBOLSCALE in the LAYER object. This is the scale at which you want the symbol to appear at the SIZE stated in the map file. You may want to modify STYLE MAXSIZE if you think that you will want your symbols to be larger than 50 pixels. Another completely different approach that just came to my mind would be to use ground units (e.g. meters) to set the size of your symbol. To do this, set LAYER SIZEUNITS to meters. Calculate the size of a symbol in meters on
[mapserver-users] Mapserver 5 Joining
Hello List, I am busy migrating my application to mapserver 5. It's quite a task and I am running into some problems. I am working on fedora with the latest mapserver release from svn.

Re: [mapserver-users] Regular Expressions with PostGIS
Hilarity ensues, same issue being debated in another thread. In your case, no, there's probably no way around it. query is implemented as a FILTER, and filter gets passed directly to the underlying data store as SQL. The syntax for FILTER in shape files is mapserver specific, the syntax for PostGIS filter is PostgreSQL specific. Store all your data in postgis :) Or, more hackily, name your layers based on their storage type. pg_layer1, shp_layer2, etc. Sorry!

Re: [mapserver-users] queryByAttributes on PostGIS-Layer
Paul Ramsey wrote: That makes some sense... but since the queryByAttribute code is based on key/value combos, it could present a uniform API, even if it implemented it different under the covers for shape/postgis. That would actually reduce the functionality compared to right now, though, since right now you can put any SQL filter you want into the API for PostGIS. You'd lose with shapefiles as well since you can pass logical and regex expressions for shapefiles and they should work. The API gives the impression that it's a key, value combo, but I think it's a doc issue, it's really a filteritem/filter combo unless I'm mistaken. I'd like to hear Steve's opinion on this one.
