I am trying to create a circle with fixed radius programatically and <FONT size=2>am using OpenLayers.Geometry.Polygon.createRegularPolygon(center, radius, sides, angle) to do that. </FONT><BR><BR>I have trouble converting my distance, say 800 feet, to the correct radius value in map units. This is what I do:<BR>
<BR><FONT size=2>
var inches = OpenLayers.INCHES_PER_UNIT;</FONT><FONT size=2><BR>
radius = radius * inches["ft"] / inches[map.getUnits()];<BR>
<BR>
The circle drawn has smaller radius than what I wanted. What's the right way of converting real distance to map units? And by 'map units', does it mean the value returned by map.getUnits()?<BR>
<BR>
Thanks for any help.<BR>
