Quality

Conceptual Consistency
The DEM surface is equivalent of a traditional and standard ground surface model and has been generated using the ground class LiDAR points. As such, the extent of the DEM varies in relation to the line of sight from the car mounted MLS sensor to the ground. In locations where the line of sight to the ground is interrupted close to the car, for example within towns or amongst close forest or cliiffs, the extent of DEM is relatively shorter than it is in more open landscapes. 
Missing Data
Complete coverage of Great Ocean Road. 
 

Lineage

Description
The DEM was generated using LiDAR point cloud class 2 (ground) to define the bare earth ground surface. LAStools las2dem command was used to generate the surface. This tool reads LIDAR points from the LAS/LAZ format (or some ASCII formats) and triangulates them temporarily into a TIN with a user defined interpolation distance. LAStools then applies a TIN to raster conversion to create the 10cm DEM raster dataset.
