East Gippsland Marine Habitats November 2009

This polygon layer represents marine habitat in the East Gippsland region mapped from satellite imagery and aerial photography with underwater video ground-truthing. The mapping was funded by Natural Heritage Trust to increase the capacity of natural resource managers to make informed decisions regarding asset identification, risk assessment, and management action targets for nearshore marine habitats in the region.

Geospatial Coverage 141,-39,150,-34
Geospatial Scale 1:20,000 (minimum)
Geospatial Accuracy The habitat layer attributes describe the dominant habitat (substratum). Overall mapping classification accuracy was determined by generating an error matrix from the video ground-truthing overlayed on the mapping. The overall mapping accuracy was 80.3% based on 127 video ground-truthing points. A lower producer's accuracy in classifying patchy reef (8% based on 25 video ground-truthing points) was primarily due to the different classification scale between the mapping from aerial imagery and underwater video interpretation. Areas classified as patchy reef in the video may have been mapped as multiple small separate areas of reef separated by sand. The mapping accuracy for all reef combined was 94% (80 of 85 video sites). Positional accuracy of the mapping is dependent on the accuracy of the source aerial photography (see the source imagery's metadata for more information), and the accuracy of the habitat boundaries is related to the mapping accuracy, which was determined by comparison with video-ground-truthing. No quantitative measure of positional accuracy was undertaken.
