I'm looking for a way to filter a bunch of areas based on a minimum area. What I'm doing is essentially creating an area of lidar point coverage and comparing it to the AOI boundary. Any areas that have missing coverage get outputted however I would like to filter these outputted areas based on their size. Sometimes some false positive returns happen because of small gaps from no returns off of water. I tried removing these smaller areas using a test filter but I'm pretty sure the area it's looking at is the total area of all missing coverage spots and not each individual area.

Hi @mackenziebudda,

Could it be that you are dealing with an aggregate (multi part) geometry? and have you tried de aggregating it before calculating the area and testing?
