Subject: [UMN_MAPSERVER-USERS] Mapfile TOLERANCE/ Mouse-click accuracy?

> Hello,
> 
> I could use a bit of help here.
> Using a simple shapefile of France, about 20 regions, under windows, 
> ms3.6 cgi, and standard html interface...
> 
> My problem is accuarcy when querying a polygon, e.g when I click on
> what 
> should be Corsica, I get the alps..
> 
> I've cranked up the TOLERANCE in my layer definition.. but all that
> does 
> is return more regions when "querying multiple" that does not really
> help..
> No projection is set in mapfile
> I've checked the shapefile with shpdump, and it reports the extents
> as 
> are in the mapfile
> The shape file queries correctly in Arcview...
> 
> could use a bit of help here..
