StreamStats computes basins using preprocessed DEM data and streamlines. Those two computations are a bit computationally intensive.


Catchments operate on TINs, and the calculations are quite a bit different than the ArcHyro D8 calculations that StreamStats uses.

Great site Fred, thanks for sharing.

I just generated a watershed boundary & imported into C3D in about 5 minutes.

Looking forward to this saving me the tedious task of tracing a watershed boundary by hand.

Thanks for the additional info Matt. The thing we like most about Stream Stats is the DEP has been accepting the data. No more methodology games. :smileyhappy:
