Handling Lidar Data

Handling Lidar Datasets

The terms of reference for the LiDAR project requested local orthometric heights.

The methodology consists in observing existing known Levelling Benchmarks and using Earth Gravitational Model 2008 (EGM2008) to derive orthometric heights from ellipsoidal data.
