I am stuck with a problem in MapInfo Pro.
I have three tables with polygons and have combined polygons from table 1 and 2 into larger polygons. Now I am only interested in the area of the ones that contain polygons from table three.
For some reason I keep getting wrong results when I make queries on that selection - it seems as though if there is 4 table 3 polygons inside the combined polygons I also get the area of the combined polygon 4 times!
When I make queries on the combined polygons I get nice results on area, number of polygons etc.. It is only when I make a selection of combined areas containing table 3 objects it goes wrong (Where condition= combined polygons.obj Contain table3.obj). For some reason the results get duplicated several times.
