[mapserver-users] setting up raster queries

[Sven Schroeter]

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
Sven

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
