Situational case: I have at leat 6+ polygon layers that I would like to combined into one major layer. So that i can calculate the toal Area of the six layer. The problem here is that there are some polygons that overlaps another polygon in another layer.

My gut feeling tells me that I'm suppose to unionize these polygon layers together. But, I do not wish to have duplicate data after unionized. maybe someone can confirm or correct me if i'm right or wrong. That would be greatly appreciated
