thank you for response<br>
<br>
I looked at the code you gave me the address.<br>
A new problem arises:<br>
1.~~~~~~~~~<br>
<h1 class="title"><small><small><small><small><small>in Class Reference:</small></small></small></small></small></h1>
int queryByPoint(pointObj point, int mode, double buffer)in the wiki's
example:<br>
<pre>layer.queryByPoint( map, pnt, mapscript.MS_MULTIPLE, 180.0 )
is this map object redundant ?
</pre>
<br>
2 ~~~~~~<br>
<br>
when I try to get grass map value <br>
it gives : <br>
<b>Warning</b>: [MapServer Error]: msQueryByPoint(): No matching
record(s) found. in <b>/var/www/htdocs/kar_pro9.php</b> on line <b>136</b><br>
<br>
<b>Fatal error</b>: [MapServer Error]: msSHPOpenFile():
(/usr/local/grass_Data0/f29/PERMANENT/cellhd/GENEL3) in <b>/var/www/htdocs/kar_pro9.php</b>
on line <b>137</b><br>
~~~~~~~~~~<br>
how can I solve the problem ?<br>
<br>
regards<br>
