[GRASSLIST:4385] wrong in page (grass-mapserver) ?

GRASS GRASS user
1

hello

I have been working on grass mapserver for some time.
in page "http://grass.itc.it/start.html" there is a demo.
in demo1 there is a grass map (soil) . When I want to query this
map with clicking on map, no value returns.

So how can I get value of "any" grass(raster) map when I click on it ?

kind regards

Ahmet Temiz

Have you looked at the raster queries wiki:

thank you for response

I looked at the code you gave me the address.
A new problem arises:
1.~~~~~~~~~

  in Class Reference:

int queryByPoint(pointObj point, int mode, double buffer)in the wiki's example:

layer.queryByPoint( map, pnt, mapscript.MS_MULTIPLE, 180.0 )

is this map object redundant ?

2 ~~~~~~

when I try to get grass map value
it gives :
Warning: [MapServer Error]: msQueryByPoint(): No matching record(s) found. in /var/www/htdocs/kar_pro9.php on line 136

Fatal error: [MapServer Error]: msSHPOpenFile(): (/usr/local/grass_Data0/f29/PERMANENT/cellhd/GENEL3) in /var/www/htdocs/kar_pro9.php on line 137
~~~~~~~~~~
how can I solve the problem ?

regards
