Attribute Quality

Comments

Indicative photogrammetric results: accuracy in easting, northing and height = 0.3m, 0.3m, and 0.3m. Measures trees, shrubs and grasses. Omission errors include dead grasses, grasses occluded by trees, and possibly deciduous trees at the time of data capture. Indicative overall accuracy for vegetation cover is better than 90% as estimated from 3 regions repeated for 2 dates to provide 6 estimates. Range from regions 90-98%. 

Positional Accuracy

Comments

Equivalent to the source ABS Mesh Blocks Dataset Positional Accuracy.
