Description

DEM and DSM were generated using LAStools. DEM was generated from ground and model key points using a triangulated interpolation surface. Hydro flattening was performed on the DEM using a semi-automated method of applying the minimum DEM height within data void regions from a 1m grid generated from all LiDAR returns excluding those classified as water. DSM was generated from non-ground point classes as a highest point in cell grid. Where no-data values exist within the resulting grid the elevation of the DEM was adopted. Contours are derived from the gridded products.
