Conceptual Consistency
The data is consistent with respect to their visual representation of the ground and non-ground features, continuity at the tile boundaries and representation of elevation values. 
Missing Data
The data is complete for the defined project extent. 
 

Lineage

Description
Reduction of the ALS data proceeded without any significant problems. Laser strikes were classified into ground and non-ground points using a single algorithm across the project area. Further classification by algorithm was undertaken to distinguish above ground features, such as buildings and vegetation. Vegetation and building classification accuracy is at least 90%. Manual checking and editing of the data classification further improved the quality of the terrain model.
