[mapserver-users] rasterquery
Hi,
I try to make a raster query using phpmapscript
My layer in the mapfile:
# DHM ESRI Grid
LAYER
NAME mydhm
DATA dhm_vg/grid/dhm_vg #grid dir
STATUS default
TYPE RASTER
TEMPLATE template/query.html
END
My php code:
//load mapfile
$map= ms_newMapObj($mapfilepath.'\map.map');
//create point
$qPoint = ms_newPointObj();
$qPoint-setXY(2554032,5521435);
//set layer
$layer = $map-getLayerByName(mydhm);
//query
@$datQuery = $layer-queryByPoint($qPoint, MS_SINGLE, 1);
if ($datQuery == MS_SUCCESS) {
echo OK!;
}
this works fine with mapserver 5.02 but there is no result with mapserver
5.6.1
apServer version 5.6.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG
SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER

SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS
SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS INPUT=OGR

Any idea?

If you you still get no results with that in place, file a ticket and assign it to me warmerdam with full details to reproduce and I'll take a look.

[mapserver-users] Define WKT shape with projection
I think I'm missing something obvious here. I'm using PHP mapscript and I have two points (epsg:4326). I want to measure the distance between the two points and get the result in meters. I've come at it a couple ways and I'm definitely getting degrees returned. Well, I think I'm just getting the simple difference between the two points. For example, I'm getting the distance between point (0,0) and (0,1) as 1. I've tried making a shape object (MS_SHAPE_LINE) and using getLength() and I've tried making two point objects and using distanceToPoint. I get the same sort of thing. I guess I'm just looking for how I can define the output unit on a dynamically created shape. Any suggestions are welcome. Thanks!

Re: [mapserver-users] Define WKT shape with projection
What I think you need to do is reproject those points to a projection that uses meters rather than degrees. You'll still be getting the same basic result where the distance between 0,0,and 0,1 is one but now the distance between those points is one meter.
