me a noob here, but i'm trying to understand the prob. remi On Thu, Aug 26, 2010 at 8:29 PM, Imran Rajjad <[email protected]> wrote: > hmmm .. but my calculated radius problem is still there.. though i > managed to calculate the vertices using geodetic distance > > > > On Thu, Aug 26, 2010 at 5:20 PM, Ralph Dell <[email protected]> > wrote: > > It will give you a polygon with 40 sides.
