[Mapserver-users] How to query (UTM) coordinates

[Tyler Mitchell]

Hi Yusuf,
I'm not quite clear on what you want to do, why don't you walk us through an 
example of how a user would interact with your application.  Tell us what you 
want to be able to do from an application use perspective, that will help us 
out.
