Parent Layer: Benthic Habitat Predictions (Apra Harbor)

Name: Benthic Habitat Map

Display Field: Habitat

Type: Raster Layer

Geometry Type: null

Description: Boosted classification trees were used to develop this benthic habitat map depicting the distribution of the 7 habitats identified by hierarchical cluster analysis. The probability of occurrence maps for individual substrate (n=5) and biological cover (n=13) types were used as predictors. The accuracy of this map was evaluated using an independent set of field data from 328 annotations at 241 sites. The overall accuracy is 86.6% and tau is 0.84 for this map.

The work was funded by the Naval Facilities Engineering Command (NAVFAC) with in-kind contributions from NCCOS.
