setting up raster queriesHi,
use MS_MULTIPLE and MS_SINGLE
e.g. with php-mapscript:
If you want only one result use
$datQuery = $layer->queryByPoint($qPoint, MS_SINGLE, 1);
if you want more results:
$datQuery = $layer->queryByPoint($qPoint, MS_MULTIPLE, 1);
Greetings

Subject: [mapserver-users] setting up raster queries
Hello,
I have a DEM file on my map so that users can click identify and get the
elevation for the location. The query works however I get anywhere between
0 to 2 records returned. Is there a way to return only a single record on a
query?
Thanks
