Hi, I have problems with the different area calculation in MapInfo and ArcView. The data is an import file from ArcView. If I calculate the area of polygons in MapInfo with SphericalArea function it is more than 1 % smaller than the one in ArcView. The function CartesianArea in MapInfo returns a more similar area calculation to the one in ArcView ? Does anybody has experience ? The projection is Gauss-Krueger.
Thank's for help in advance. Kerstin
