Lineage
- Description
- The DEM was generated from the point cloud (class 2 - Ground). ArcGIS 9.2 Terrain Grids were derived using the Natural Neighbor interpolation. This method uses the closest triangles and applies weights to the proportionate areas from the grid cell centroid to interpolate the value. It uses known elevation data, it does not make any predictions regarding the surface and accurately depicts existing troughs and peaks in the data and supports irregular point spacing, which suits the nature LiDAR data. Hydro boundary polygons were incorporated into the LASD dataset. The LASD to DEM grid generation process was run with the hydro boundary polygons included.
