Visitor's Map

This is an easy to read map describing roads, populated places, places of interest and local legal boundaries called parishes. These map layers can be overlaid with a geo-referenced Tourism Map published by the Department of Tourism, Landsat ETM+ satellite imagery, and digital elevation (DEM) maps.

Environmental Map

This is a collection of terrestrial-themed digital layers including inland water bodies (drainage, water bodies and watersheds, and PGDM flood zones), mangrove locations, hypsographic features (e.g., hills, points cliffs), and other physical features of Antigua. The layers can be overlaid with satellite images, and elevation maps of Antigua.

This is a compilation of coastal ocean based digital layers including hydrographic features (e.g., bays, harbors and channels), living resources such as coral reefs and mangroves, and ocean depth (GEBCO).  This map also contains the summarized site data for the Antigua AGRRA coral reef and fish survey conducted by NCORE in August 2005.

Landuse Map

This is a land use map of Antigua.  The landuse data in this map were created for the Post-Georges Disaster Mitigation Project implemented by the Organization of American States, Unit for Sustainable Development and Environment.  The map classifies all land features in Antigua according to the following scheme: airport, industrial, military use, landfill, urban settlement, tourism, recreational/historical area, agriculture, citronella field, improved pasture, mixed scrub and/or rough grazing, woodland, swamp/mangrove, fresh water, and salt water ponds.
