Lineage
- Description
- Laser strikes were classified into ground and non-ground points using a specifically designed algorithm applied across the entire project area. The quality of the classification was further improved by manual checking and editing of the ALS data using intensity imagery and orthophoto imagery as a reference. Following classification, LiDAR files were exported into XYZI textfile format.

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.
