There two ways to draw circles:
- use a circle layer
- or use a circle symbol
The latter is probably more interesting for you when you combine it with
SIZEUNITS. With that you can do stuff like:
SYMBOL
NAME 'a circle'
TYPE ELLIPSE
POINTS 1 1 END
FILLED TRUE
END
LAYER
NAME 'some circle'
TYPE POINT
...
SIZEUNITS KILOMETERS
CLASS
STYLE
SYMBOL 'a circle'
SIZE 10
COLOR 255 0 0
END
END
END
This snippet will draw circles 10km in diameter at each data point. Hope
this helps.

Hi
I am trying to draw a circle around a given point at given radius in a
map server generated image.
Due to the platform I am using its impossible to use mapscript , php or
javascript.
Is it possible to do something like this by using the symbolset file ?
Is it possible to do something sly with polygon file ?
David.
