Sorry if I've overlooked some existing documentation or discussion on
this topic, but I've just spent several hours googling Cartoweb and
Mapserver resources and have learned lots of things but no answer to
Is it possible -- "out of the box", or with some plugin or
not-too-crazy coding -- to convert the mouse location display from the
native projection/coordinate system of the map data into another system?
Specifically, I have a project with all of the data in Massachusetts
State Plane (GRS 80, Lambert Conformal Conic, etc), so the real-time
display as the user mouses over the map are in Eastings and Northings
(meters). This will mean nothing to the typical user, so I'd like to
convert those numbers on-the-fly to latitude and longitude. Any hope?
Related idea would be to let the user enter lat, lon in the recenter
boxes and convert them to the appropriate native map projection to
recenter the map...
Thanks for any info, tips, advice, or sympathy!
