Geomorphon Common Forms in North Carolina
The 10 most common geomorphic features are identified for the state of North Carolina using Lidar derived DEMs at 30 ft. resolution. This product uses r.geomorphon, a feature in GRASS GIS, to calculate the geomorphic features for the state. The tool requires a user input length scale and slope for calculation. This dataset uses 60 cells, or 1800 ft. as the length scale and two different slope values of 1 degree (Blue Ridge/Piedmont ecoregion) and 0.0001 degree (Coastal Plain ecoregion).
