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?
