Lineage Contours were generated from the LiDAR digital elevation model (DEM) using the freeware GIS package Quantum GIS. When compared to a sample area generated from the same data but using ArcMap, the contours were of equal or better quality.
Positional Accuracy The contours generated from the DEM will replicate any inaccuracies of the DEM. As a guide, the DEM data is vertically accurate to 15cm and horizontally accurate to 30cm.
Attribute Accuracy Not Relevant
Logical Consistency Not Relevant
Completeness The 0.5m contours are complete for the extent of the Cocos (Keeling) Islands.
