i have 2 point feature layer (file GDB), each layer have a lot of point feature (records with depth value), around 80.000.000-100.000.000 records/point. there are overlapping area between those layer (15-20%) and in the overlap area, the point are intersect perfectly (the points are overlap perfectly in overlap area).
i need to delete those points in the overlap area (1 of those layer) so when i overlay or merge both layer, no duplicate point feature.
i have several method :
merge those layer, use find identical and delete identical. or
generate x-y in those layers, select the points in the overlap area , use select by location (intersect model) between 2 layers, then unselect 1 of the layer, and delete the points in other layer.
my problem is, both method makes my computer crash. i have 64 GB ram, i7 proccessor, 32GB VGA that is a really great spec right.
so any better solution?
