[mapserver-users] querybypoint in MS 3.5

[Mark Giesbrecht]

Hi All,

Love this Mapserver; coupled with mapscript, this application is
incredible.  I'd also like to praise the developers who have made
mapserver/mapscript so great.

On that note,  I've been having some problems recently with a cgi-based
point query that used to work with 3.4.  I can query a polygon layer,
but when it comes to a point layer, I get the following error:

mapserv(): Web application error. No way to generate a valid map extent
from selected shapes.

As I mentioned before, this works with a polygon layer.  Below is my cgi
call using the stock PNG
version of the Windoze binaries; the output for the executable is:

MapServer version 3.5 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ
SUPPORTS=
TTF SUPPORTS=WMS_SERVER INPUT=TIFF INPUT=EPPL7 INPUT=JPEG
INPUT=SHAPEFILE

Any pointers would be greatly appreciated.

CGI call:
http://www/cgi-bin/mapserver/ms35png/mapserv.exe?map=c:/program
files/apache
group/apache/htdocs/clientdemos/eman/eman_mscr.map&layer=Stations&mode=query&imgsize=692+560&img.x=210&img.y=261&imgext=-2980391.5374492323+11401587.175669793+4678530.106513312+5199369.812202809&mapext=shape&map_scalebar_status=ON

Included is the layer from my mapfile
