Hi I'm looking a Mapinfo SQL which I can look at two tables and easily determine, instead of having to the the long winded way in excel etc, if a particular smaller bounded polygon has now moved into a different larger bounded polygon because there has been recent redistribution of particular boundaries of the larger. I releasing it shouldn't be that hard, however the problem I have is that the smaller may fact be intersected by more than one of the larger and the cost's involved the vary significantly. I have been able to table before and after, and determine any differences, I guess looking for a query that looks at the two tables and says ok for smaller polygon WXYZ before you intersected larger polygon 1, but now you intersect larger polygon 1, 2 and 3. Btw I have over 5000 smaller polygons whereas I only have a total of 4 categorised larger polygons. Can anyone help? Or let me know if I didn't make sense. Cheers
