This sounds strange to me. Which calculation method do you use ? Spherical or Cartesian ?
Normally the spherical area will be approx. 0.5 % smaller than the cartesian area. Have you made sure that the length of the side in the region are exactly 100 meter when imported into MapInfo ? How do you import it into MapInfo ? Peter Horsb�ll M�ller GIS Developer Geographical Information & IT COWI A/S Odensevej 95 DK-5260 Odense S.

In an ambient CAD we have a squared object or rectangle of 10000 m2 or 1 hectare, when it is imported in MapInfo with the wanted spherical projection (UTM PSAD 56 Zone 18 South) the resulting area is bigger in 39 m2, being this too big difference. Is my consultation as MapInfo it calculates the area? which is the it formulates used in this I calculate?, this because when it is changed to Cartesian system, the area between CAd and MapInfo is the same I expect your help Javier Quispe .:------------------------------------------------------------:.
