The Protected natural areas of the U.S. Virgin Islands, compiled and identified by the U.S. Virgin Islands Gap Analysis Project (USVIGAP), display terrestrial protected natural areas designated for natural resource conservation in the U.S. Virgin Islands, as well as areas with government regulation that have the potential to protect natural resources. The protection of natural areas is an essential step in conserving biodiversity and maintaining ecosystem services. The benefits and services provided by natural areas include clean water and air, sustainable wildlife populations and habitats, stable slopes and productive soils, genetic reservoirs, recreational opportunities and spiritual refugia. These benefits are...

The U.S. Virgin Islands 2007 land cover, created as part of the USVIGAP analysis project supported by the USGS, is a forty-nine class land cover classification. The USVIGAP land cover is based primarily on the unsupervised classification of five Earth Observing 1 (EO-1) Advanced Land Imager (ALI) scenes acquired in 2007. The ALI scenes were processed, segmented into geoclimatic zones and classified individually. ASTER and Landsat 7 ETM+ imagery from 2008 and 2009 were used to complete areas of no data resulting from cloud and cloud shadow in the initial ALI classification. The land cover was created through the use of the spectral information derived from the satellite imagery and ancillary data such as geology,...

The Puerto Rico 2000 land cover, created as part of the Puerto Rico GAP Analysis project supported by the USGS, is a seventy-class land cover classification. The PRGAP land cover is based primarily on the unsupervised classification of eighteen Landsat 7 Enhanced Thematic Mapper + (ETM+) scenes acquired from 1999 - 2003. The Landsat 7 scenes were separated into wet and dry season imagery, mosaiced, and segmented based on geo-climatic zones. The land cover was created through the use of the spectral information derived from the satellite imagery and ancillary data such as geology, topography, hydrology and land use history. The Puerto Rico GAP 2000 land cover product represents the first time a 15 meter spatial resolution...
