This should help.

Subject: [UMN_MAPSERVER-USERS] point query precision



Hello folks,
 
I am making use of MapServer 4.6 and am pulling point data from sql server 2000. I just recently implemented query mode as a drop-down option on my cgi-generated map but I find that clicks on the map often do not generate results, especially after a number of zooms via browse mode. I am suspicious that mouse precision may be at odds with the query or, heaven forbid, the mouse click xy reference is not transferring well to the latitude/longitude in my sql server table. Is there a method to broaden the mouse click coverage or decrease the click precision in the map file to ensure that query mode clicks will generate results as they should?
 
Thanks for any assistance,
 
David P. Shorthouse
