- Description
- A full boresight of the ALS sensor was performed on the 12th of January, 2008. The resulting parameters were used in the processing of the datasets. Airborne GPS data was collected during the acquisition mission for each flight line. During the data acquisition the Positional Dilution of Precision (PDOP) for the airborne GPS was monitored and held at or below 2.5 when possible. The ground control and airborne GPS data stream were validated through Fugro's Geodetic Validation process. The ALS-data was validated in the same Geodetic Validation process. LiDAR elevation data was validated through an inspection of edge matching and visual inspection for quality (artefact removal). The following methods are used to assure LiDAR accuracy. (1) Use of IMU and ground control network utilizing GPS techniques, (2) Use of airborne GPS in conjunction with the acquisition of LiDAR, and (3) Measurement of quality control ground survey points within the finished product.

Conceptual Consistency
- Comments
- ALS strikes on water bodies have been omitted from the dataset. The definition of the ground under trees may be less accurate.
Missing Data
- Comments
- The LiDAR datasets representing various ground and non-ground features are complete for the defined project extents.
