@remi...my problem is simple, I`m trying to draw a circle by giving centre lat/long and radius in meters.
in my first email I mentioned that I`m doing this already in native javascript through basic trignometry but I was looking for somthing in openlayers @Ralph..hmm ok buddy.. I`ll try that out,appreciate your help regards, Imran On Thu, Aug 26, 2010 at 5:50 PM, remi <remiglo...@gmail.com> wrote: > Hi imran, > i don't really get your problem.
