Quality

Conceptual Consistency

ALS strikes on water bodies have been omitted from the dataset. The definition of the ground under trees may be less accurate. 

Missing Data

The LiDAR datasets representing various ground and non-ground features are complete for the defined project extents. There are small holes/gaps between some runs in the following tiles e328n5752,e328n5750,e238n5750. 

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.
