I am trying to develop a Add In that will help the user automatically point out changes in a new layer(Polygon).
Case: I have two feature classes of state polygon data say. One feature class is old and the second is new. I need
to some how compare the two layers and select features in the new layer that do not exist or have been modified in the old layer.
I have to do this spatially. I am currently using overlap for starters...
How can I achieve this using arcObjects?
