Native lidar data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. The 3-D position data are sub-divided into a series of LAS files, which are tiled into 1-km by 1-km boxes defined by the Military Grid Reference System. In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, and the RGB imagery are also available. These data are available for custom download at the links provided in the URL section of this metadata record.
