[OpenLayers-Users] Accuracy of OpenLayers at scales less than 1:15000

[Jean-Marc Strydom]

Hi Arndt

That did the trick !  Much more accurate - more accurate than what we need, 
although positioning does go slightly out at very large scales (ie. down to 
1:200) but the key thing is that the mouse position is correctly reflected 
in the displayed cords and that the mouse event picks up the correct land 
parcel.  Thanks ever so much.  BTW, why would those parameters affect the 
map ?

Regards
Jean-Marc
