Name: WorldView 2 Mosaic (Water-column Corrected)

Type: Raster Layer

Geometry Type: null

Description: This GeoTiff is a mosaic of World View 2 panchromatic satellite imagery of Northeast Puerto Rico that contains the shallow water area (0-30m deep) of the Northeast Ecological Reserve: including the waters off of Fajardo and Luquillo, to the Former Roosevelt Roads Navy Base, the Vieques Sound, La Cordillera Reserve, the Luis Pena Reserve, and the waters around Culebra Island. The WV2 imagery was processed using PCI imagery analysis and ArcGIS to create a continuos, color balanced mosaic. The DigitalGlobe WV2 is a commercial high resolution (0.5m - 1.5m) multi-spectral satellite that surveyed the NER area in 2011. The enhanced Red, Green, Blue, Yellow, Near Infrared, and Oceanic Blue color bands allowed the Biogeography branch to delineate habitats using feature extraction tools in Envi 5.1 software. The multispectral bands were analyzed to detect coral reefs and seagrass beds under the surface of the water, as well as features above the surface, such as mangroves, salt ponds, and the shoreline edges. The WV2 mosaic, the bathymetry model, principle component analysis, and aerial imagery were all used integrally to create the NER Benthic Habitat Map.
