If you can get UTM coordinates from the mouseclick, the next best option (in my
opinion) would be to use proj4js:<br>
<br>
<a href="http://proj4js.org/" target="_blank">http://proj4js.org/</a><br>
<br>
Simply embed the js-library ad an event for mouse handling and convert:
screen->utm->4326. <o:p></o:p></span></font></p>

be fairly straightforward, but I was wondering what is the easiest and quickest
way to convert coordinates on the fly. All my data is in UTM
coordinates. I want to report coordinates to the screen in
Lat/Long. Changing the projections on the map files to lat/long
(EPSG:4326) is not an option, as this will cause problems elsewhere. So
what I want to do is take point coordinates, either from a mouse click or from
UTM coordinates, project to lat/long, which will be reported in a result
window. What is the quickest way to do this?</span></font><o:p></o:p></p>
