Hi all,
I am trying to wrap my head around a situation that I have and what the output would be. I have been running tests to see what the answer is but don't want to make sweeping assumptions on them.
I have a feature class, let's say "FIRE". In this Fire feature class there are burns across a landscape and some of these burns occur on top of other burns. I am trying to confirm which value comes through to the end product of my feature class to coverage. As in a coverage only 1 feature can contain any 1 space, I need to ensure that it is the most recent fire coming through. What I am seeing in my tests is that if a large area encompasses a smaller one, the smaller feature's linework comes through and its values are retained, effectively deleting the same area within the larger (LG=100ha, SM = 10ha: LG = 90, SM=10 in final output). I need to ensure that in instances where the small area is "younger" then the larger area, that the larger area comes through.
Thoughts?
