Eighteen distinct and non-overlapping biological cover classes were identified that could be mapped through visual interpretation of remotely sensed imagery. Cover classes refer only to the dominant biological component colonizing the surface of the feature and do not address location (e.g., on the shelf or in the lagoon) or structure type. Habitats or features that cover areas smaller than the MMU were not considered. The cover types are defined in a collapsible hierarchy ranging from eight major classes (Algae, Seagrass, Live Coral, Mangrove,
Coralline Algae, No Cover, Unclassified and Unknown), combined with a modifier describing the distribution of the dominant cover type throughout the polygon (10%<50%, 50%-<90%, and 90%-100%). |
