Limitations of FACET. The accuracy of FACE … Limitations of FACET. The accuracy of FACET output depends on the quality and resolution of the DEM used. The user should not interpret FACET stream and floodplain geomorphic measurements as a replacement for on-the-ground measurements of geomorphic characteristic. Rather, FACET provides a tool to rapidly assess patterns in geomorphic characteristics at a regional scale. Any FACET output should be screened for outliers and abnormalities.e screened for outliers and abnormalities. +

The units are always in meters. This parameter is the resolution to which the user wants the DEM resampled to. FACET uses ‘resample resolution’ to set the cross-section point distances parameter i.e. ‘xnptdist’. This ensures bank point spacing aligns with the DEM’s resolution. spacing aligns with the DEM’s resolution. +

FACET is a Python tool that uses open sour … FACET is a Python tool that uses open source modules to map the floodplain extent and derive reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs). Geomorphic measurements include channel width, stream bank height, floodplain width, and stream slope.<br>Current tool functionality is only meant to process DEMs within the Chesapeake Bay and Delaware River watersheds. FACET was developed to batch process 3-m resolution DEMs in the Chesapeake Bay and Delaware River watersheds. Future updates to FACET will allow users to process DEMs outside of the Chesapeake and Delaware basins.<br>FACET allows the user to hydrologically condition the DEM, generate the stream network, select one of two options for stream bank identification, map the floodplain extent using a Height Above Nearest Drainage (HAND) approach, and calculate stream and floodplain metrics using three approaches. stream and floodplain metrics using three approaches. +
