Description: Stream banks were manually digitized through visual interpretation of slope and elevation models derived from the LIDAR point cloud as well as the digital imagery provided by Eagle Aerial Solutions.
Description: Cross sections from the 2016 analysis with a spacing of every 250’ were reutilized. Where necessary, cross sections were extended to span the full width of the stream as defined by the 2021 bank polygon and further extended by 15% of the 2021 stream width beyond each bank. Each cross-section was then split into stations every 0.5 feet and assigned both landcover and elevation attribution. Each cross-section has unique ID. A single CSV text file, containing landcover and elevation information for each cross section and each station on that cross section has also been provided.
Description: Centerlines were generated equidistant from each stream bank. Elevations were then assigned to each vertex in both the banklines and centerlines, creating 3D feature classes. The centerline does not represent to true thalweg of the stream; therefore, an additional elevation smoothing algorithm was applied to the centerline to enforce downstream flow.
