Lineage
- Description
- The ground LiDAR points were used to generate a "bare-earth" DEM. The ground data points were imported to a "point" feature class in ESRI ArcGIS. Following the import to ESRI format, the points were converted to a Terrain Data Type and then interpolated into regularly spaced 1m grids. The grid files were finally exported to XYZ ascii format.
