Abstract | Representation of 2' Contours for the Watershed Area Bare Earth with waterbodies removed. |
Purpose | Contours for 2' elevation were generated from 3' Digital Elevation Model (DEM). The DEM was based on 2014 flight for LiDAR and aerial photographic data acquisition. DEM was clipped to BES watershed boundaries with waterbodies removed. Areas were then contoured based on west side, east side and islands (land masses with shape area greater than or equal to 8000 sq.ft.) Then all contours with a shape length < 30' were removed. Contour (line smoothing) was then accomplished. |
