Do you know of any good web sites covering computational geometry / GIS algorithms. I am interested in polygon/polygon intersection and buffering but not circular buffering i.e. if you have a polygon I need an algorithm that creates a buffer of equal size all round the polygon so that the buffer mimicks the shape of the polygon.   regards, andrew bailey
