Do you use a client like OpenLayers? What programming language(s) do you use? Is your datasource a database? Like postgis?<br>
<br>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. <br><br><br><br><br><div class="gmail_quote">

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">This should 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 (<i><i><font face="Arial"><span style="font-family: Arial; font-style: normal;">EPSG:4326)</span></font></i></i>
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></p>
