Change Detection

Question

Hello I'm Trying to do a change detection on two polygons which are the same shape on the main section but the inside is different I'm trying to compare two landuse polygons? if anybody would have any insight on this issue please reply.

Here's an idea, not sure if it is suitable: I am assuming you have two polygon feature layers of the same area, one before and one after. If each polygon contains some land use code or classification information, then I can suggest that you try to use the Intersect tool to intersect them to create an output polygon that has attributes from both the input polygons. By comparing the landuse attribute columns inherited from the two inputs respectively, you can identity those with a change in landuse. Let me know if it's what you need.
