TauDEM
The Terrain Analysis Using Digital Elevation Models (TauDEM) toolset generates key terrain and hydrologic derivatives from a digital elevation model (DEM) and channel network. It provides essential inputs for other Riverscapes tools or can be used as a product of its own.
The Riverscapes compliant, production-grade TauDEM package utilizes select algorithms from the original TauDEM suite developed by David Tarboton at Utah State University's Hydrology Research Group and packages inputs and outputs into a Riverscapes project.
Riverscapes TauDEM projects input a DEM and channel to produce the following outputs:
- Pit-filled DEM
- D-infinity flow direction raster
- D-infinity contributing area raster
- Topographic Wetness Index (TWI)
- Height Above Nearest Drainage (HAND) raster
- D-infinity slope raster (percent)
- Additionally, produces a D-8 slope raster (degrees) using GDAL.
