Layer: Structure (Shallow) (ID: 54)

Parent Layer: St. John USVI (2009)

Name: Structure (Shallow)

Display Field: ZONE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Sixteen distinct and non-overlapping geomorphological structure types were identified that can be mapped by visual interpretation of remotely sensed imagery. Habitats or features that cover areas smaller than the MMU are not considered. For example, sand halos surrounding patch reefs are often too small to be mapped independently. Structure refers only to predominant physical composition of the feature and does not address location (e.g., on the shelf or in the lagoon). The structure types are defined in a collapsible hierarchy ranging from four major classes (Coral Reef and Hardbottom, Unconsolidated Sediment, Other Delineations, and Unknown), to sixteen detailed classes (Rock Outcrop, Boulder, Spur and Groove, Individual Patch Reef, Aggregated Patch Reefs, Aggregate Reef, Reef Rubble, Pavement, Pavement with Sand Channels, Rhodoliths, Sand, Mud, Sand with Scattered Coral and Rock, Artificial, Land, and Unknown).
