Lineage
- Description
- The DEM was derived from a ground model generated by triangulation of the LiDAR points classified as ground, model keypoints and water with points exported on the even metre. Gaps of up to 50m are interpolated and filled by triangulation of the surrounding cell values. Dams and lakes larger than 625m2 have been hydro-flattened.

Conceptual Consistency
- Comments
- The DEM has been interpolated from returns classified as ground, keypoints or water only. Accuracy may be reduced in areas of diminished returns.
Missing Data
- Comments
- Gaps greater than 50m2 may be present in areas of diminished returns over water and under dense canopy.
