This map, as well as other related layers, was produced by The Nature Conservancy (TNC), the Asner Lab of Arizona State University, and Arizona State University's Global Airborne Observatory (GAO). GAO is an airborne laboratory that collects high resolution (1m) coral health and habitat information to inform effective coral outplanting site selection with increased survivorship. The GAO plane flies at an altitude of 1000m and collects 427 samples of light per pixel that correspond to the chemistry of corals, generating 324 GB/hour of data. Data is processed on a cluster machine matching spectrometer information with high-precision positioning data at an accuracy of 7-10cm. Hyperspectral imagery was collected by ASU's Global Airborne Observatory (GAO) for The Nature Conservancy in Saint Croix, U.S. Virgin Islands and the Dominican Republic. ASU derived high-resolution maps from this aerial data representing: bathymetry, live coral cover, fine habitat complexity, algal cover, seagrass cover, and sand cover. TNC scientists used water surface drone imagery to collect high-precision GPS data and to predict percent live coral to train the machine learning model. These datasets are available at CaribbeanMarineMaps.tnc.org. Live coral cover, algal cover, seagrass cover, and sand cover layers are percentage layers that have been converted to integers through multiplication by a factor of 100. For example, a live coral cover value of 2250 represents 22.5% live coral cover. For publication of the Saint Croix live coral cover map to the EMODnet Seabed Habitats Project, SAERI merged five separate raster layers obtained from TNC. The original five layers represented live coral coverage at different areas around Saint Croix. Layers were merged in QGIS v3.28.4. This dataset is View Only on EMODnet.
