Completeness Commission
evaluation Method Description
These data covered the required survey area with minimal gaps in data coverage except near tops of mountains. These gaps are
caused when the ground elevation rises so steeply that the lidar swath (based on maximum scan angles and altitude) from adjacent
flight lines no longer overlap. These gaps are at elevations above the maximum required for this project. The data postings
are very consistent with nominal posting density of 1.3 meters.

measure Description
The data provided in this file were tested against ground truthed data. At these locations the lidar data matched within 0.20
meters, and different flight line data agreed within 0.20 meters.
