Or perhaps I meant SpatialFilter... (arrgh)

Jason -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of mrmcclurg Sent: Monday, September 25, 2006 08:06 To: [email protected] Subject: [fme] Polygon Compare Hi Everyone, I'm trying to develop a tool that will allow me to extract areas where two polygons DON'T overlap, this will be used to see where data coverage does not exist. Let me break it down: We have a rectangular block of where data should be, and usually is, however, we also have a data extents layer, which shows us exactly where our lidar data goes to. What I need to do is to extract the areas from the rectangular block where the data extents DO NOT exist, and this also has to be compared one row at a time. Each line will have a specific flightline number to compare to. We cannot compare a rectangular block from one flight line, with the data extent of another. Any suggestions on where to start?
