Hi all, I'm using the extent function to get the geographic coverage of a table. That function returns a bounding box, i.e. a polygon with 4 points (XMin YMin ...etc). I do know that the actual coverage of teh table is not a four points polygon but an arbitrary polygonal shape with many vertexs. I want to get this shape form the same table. There is any function or operation that can give me that shape? Regards, Oscar
