Abstract

This original dataset was downloaded from the Shuttle Radar Topography Mission (SRTM) 1 Arc-Second Global Dataset (https://lta.cr.usgs.gov/SRTM1Arc). The DEM was projected to UTM and resampled to 150m grid cell. Terrain analysis steps included pit filling and a subtraction of elevation along the stream network to 'burn in' the flow pathway to allow flow directions to drain low elevation areas to the outlet at the Sauk River confluence with the Skagit River.
