[mapserver-users] How to create [n]mile radius polygon(circle)

[Ed McNierney]

John -

You could use a simple circle symbol (i.e. a square ellipse) and set its
SIZE appropriately.  You would need to do the math to convert miles to
pixels in order to set the symbol SIZE.

How can i create a [n]mile radius circle either with a polygon or
symbol.

I have managed to create a crude oval octigon based on 12 lat/long
points
but I cant seem to get a smooth circle or the correct mile radius.
