I am trying to create a circle with fixed radius programatically and am using
OpenLayers.Geometry.Polygon.createRegularPolygon(center, radius, sides, angle)
to do that.
I have trouble converting my distance, say 800 feet, to the correct radius
value in map units. This is what I do:
var inches = OpenLayers.INCHES_PER_UNIT;
radius = radius * inches["ft"] / inches[map.getUnits()];
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()?
Thanks for any help.
Cynthia
