Aerial topographic LiDAR was acquired by Quantum Spatial in 121 lifts. LiDAR sensors used include Leica ALS70, Leica ALS80, Optech Orion H300, Riegl VQ1560i, and Riegl LMS Q1560. Data was collected at an average point density of 2.5 pts / m2.
The measured non-vegetated vertical accuracy (NVA) is 0.089 m or 3.5 inches. The vegetated vertical accuracy (VVA) is 0.283 m or 11.1 inches. Vertical accuracy is reported because it is generally less accurate than the horizontal measurement, and as a result, is the limiting factor for application of the data.
