I don't have any expertise either but here's a conjecture:
I'm a lumberjack and I'm okay... I want to buy 1000 Acres of pristine forestland and then spend 8 years wrangling with the government for the right to log it. So how much wood could I cut if I could cut wood?
If I remember correctly (One of the founders is an acquaintance), logging companies frequently have large parcels of land of varying quality, size, and even contiguity. Being able to cheaply determine the the composition of the trees on these disparate parcels better allows them to determine which areas would be most lucrative to develop logging operations (an enormous capital investment) in, which is incredibly valuable.
