Layer: Percent Hardbottom (ID: 6)

Name: Percent Hardbottom

Display Field: P_HARD

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Six unique and non-overlapping percent hardbottom classes were mapped by visually interpreting aerial photos and acoustic imagery. Percent hardbottom refers to the amount (i.e., patchiness) of hardbottom habitat within a habitat polygon. It does not describe the type of hardbottom that is located within a polygon. Six range classes were used (i.e., 0%-10%, 10%-30%, 30%-50%, 50%-70%, 70%-90% and 90%-100%). Habitats or features with areas smaller than the MMU or minimum mapping unit (1000 m2) were not considered. "Unclassified" denotes that an estimate of percent hardbottom is not appropriate for this particular structure class (e.g., for Land polygons). "Unknown" indicates that the amount of hardbottom was indistinguishable in the aerial orthophotos or acoustic imagery due to interference with the signature of the seafloor.
