Working on the edge…
Problem…
UAV data has been collected over a large area +1,500 sq/km. The UAV’s used were small and as such the area was divided into 200+ zones each of which were then processed into individual Geotiffs. The data was collected without absolute accuracy and as so although the data within a given zone is relatively accurate there are varying degrees of edge matching issues when attempting to put all 200+ zones together.
Attempted solution…
A post processing process that would attempt to take individual zones and automatically do adaptive filtering of zones and then attempt to match using edge matching.
Test Data…
A 27 Zone section was selected as the same dataset.
Preliminary Result…
3km x 3km Zone.

at a glance it looks good, so lets look a little closer…
We selected two zones…
