Data Layers Produced by TauDEM

Intermediates

Pit Filled DEM

The input DEM with the TauDEM Pit Remove algorithm applied to it.

D-infinity Flow Direction Raster

Flow direction raster produced by applying the TauDEM D-infinity Flow Directions algorithm to the pit filled DEM.

Rasterized Channel

The input channel polygon or line network converted to a raster where the channel cells have the value 1 and all other cells have the value 0.

D-infinity Slope Raster

Slope raster produced by applying the TauDEM D-infinity Flow Directions algorithm to the pit filled DEM.

D-infinity Specific Catchment Area Raster

A raster of specific catchment area produced by applying the TauDEM algorithm to the D-infinity flow direction raster.

Outputs

Height Above Nearest Drainage Raster

A raster where each pixel value is the height above the nearest drainage area, produced using the D-infinity Distance Down TauDEM algorithm.

Topographic Wetness Index Raster

A raster of Topographic Wetness Index produced using TauDEM's application of the algorithm.
