<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi, Bob<br><br>perhaps you can try these steps:<br>1. in your *.map file, set UNITS part into DD and set PROJECTION into 'proj=longlat' like below:<br>MAP<br> NAME DEMO<br> # Map image size<br> SIZE 500 300<br> UNITS dd<br> TRANSPARENT ON<br> <br> FONTSET etc/font.txt<br> <br> EXTENT 93.812567 -17.025526 143.016024 12.672460<br> PROJECTION<br> 'proj=longlat'<br> 'ellps=WGS84'<br> 'datum=WGS84'<br> 'no_defs'<br> ''<br> END<br><br>2. and to display the extent in decimal degrees, perhaps you should change 'Map Units' of your original map data<br>from 'Meters' into 'Decimal Degrees' <br>this can be done by using any GIS software, for example: QuantumGIS<br>and then, set the same EXTENT in your *.map file and
your map data's extent<br><br>i hope this helps. <br>because it works in my ka-map application, i have map data that are already in <br>decimal degree format. and above is my *.map file setting<br><br>Regards<br>donny<br><br><br>--- On <b>Fri, 3/13/09, Bistrais, Bob <i><Bob.Bistrais@maine.gov></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">From: Bistrais, Bob <Bob.Bistrais@maine.gov><br>Subject: [ka-Map-users] Displaying extent in different units than map units?<br>To: ka-map-users@lists.maptools.org<br>Date: Friday, March 13, 2009, 2:55 AM<br><br><div id="yiv164414552">

The user would like to see the cursor location and extent displayed in Decimal
