Converting multipolygons to polygon

Sep 14, 2014 at 7:54 AM
I have converted a set of gps points to polygon and then using .makevalid() I saved them in sql server.But It converted them to multypolygons.Is there any way to fix this problem and convert them to polygon?I know that this gps points are boundries of properties so they can not be multi polygons or polygons with holes and things like that.. I use dotspatial liberary ,So I face a problem casting a multypolygon as a polygon while I want to use them..If I use union or other tools like that does it works?Any idea how to fix this probem..Thanks
