Layer: Structure (ID: 5)

Name: Structure

Display Field: D_STRUCT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Twelve distinct and non-overlapping geomorphological structure types were mapped by visually interpreting aerial photos and acoustic imagery. Geomorphological structure refers to a feature’s dominant physical composition and does not address geographic location (e.g., in a Lagoon). Structure types are defined in a collapsible hierarchy ranging from three major classes (Coral Reef and Hardbottom, Unconsolidated Sediment, and Other Delineations), to fifteen detailed classes (Aggregate Reef, Aggregated Patch Reefs, Individual Patch Reef, Pavement, Pavement with Sand Channels, Rock/ Boulder, Spur and Groove, Mud, Sand, Sand with Scattered Coral and Rock, Artificial and Land). Habitats or features with areas smaller than the MMU or minimum mapping unit (1000 m2) were not considered. "Unknown" indicates that the structure type was indistinguishable in the aerial orthophotos or acoustic imagery due to interference with the signature of the seafloor.
