Allen Coral Atlas Global Benthic Habitat Maps: Jamaica
This map shows the benthic habitats surrounding Jamaica. This map is originally part of the wider Allen Coral Atlas Global Benthic Habitat Maps dataset found at www.allencoralatlas.org. The Allen Coral Atlas dataset maps the benthic habitat for the world's shallow coral reefs at 5 m pixel resolution. The Allen Coral Atlas brings together partners from Planet, University of Queensland, Arizona State University's Center for Global Discovery and Conservation Science (GDCS), the National Geographic Society and Vulcan Inc. to take high resolution satellite imagery and advanced analytics to map and monitor the world's coral reefs in unprecedented detail. Global Benthic Habitat Maps characterise different coral reef bottom types. These bottom types include communities of living organisms attached to the reef (benthos), as well as sediments and underlying substrate. The six Allen Coral Atlas Global Benthic Habitat Map classes used were developed by Roelfsema et al 2013* with input from other coral reef benthic classifications. This classification maximizes the breadth of information available from Planet Dove remote sensing data to create the best set of classes to support users.

The Allen Coral Atlas is a global-scale coral reef habitat mapping project that uses Planet Dove 3.7 m resolution daily satellite imagery (in combination with wave models and ecological data) to create consistent and high detail global habitat maps to support reef-related science and conservation. The underlying satellite image data are temporal composites of PlanetScope satellite imagery spanning 2018-2020. The habitat maps are created via a machine learning approach with contextual editing, using a range of imagery, bathymetry and derived products as input data, trained via a globally consistent reference data set. Habitats were categorized using the following Global Benthic Classes: Sand = soft-bottom area dominated by fine unconsolidated sediments. Rubble = loose, rough fragments of broken reef material. Rock = exposed area of hard bare substrate. Seagrass = seagrass is dominant biota. Coral/Algae = hard-bottom area supporting living coral and/or algae. Microalgal Mat = visible accumulations of microscopic algae in sandy sediments. Unknown = a data constraint means the area is not allocated a Global Benthic Class. Due to the large size of the original benthic map that covers the northern Caribbean, SAERI divided the original map into regions to allow more efficient cleaning and processing of data. To do this, SAERI clipped the original Benthic Habitat Map to different countries, creating individual country-level maps with unique GUIs. In cases where a regional breakdown still resulted in too large a file to work with, Saeri further broke doen the region into parts and treated each part as a separate map with its own GUI. SAERI cleaned the maps in mapshaper.com using the -clean function, edited the data to fit with the Data Exchange Format, and removed any holes with an area less than 25m^2.
