Tree Fall Detector

[bw4sz]

Criteria for a tree fall:

• A drop in height of more than X meters?
• An absence of a polygon prediction in that space?
• A change in polygon centroid of more than x meters? Trying to capture what happens if a neighbor tree grows into the space.

Perhaps just pull out a 100 examples of criteria one and get a sense for the false positives.
