USGS Gap Analysis Program has created interactive maps for viewing its data sets. Each of these Viewers enables users to browse and download all or parts of the data sets.
LAND COVER VIEWER
The National Land Cover Viewer displays data on the vegetation and land use patterns of the continental United States. It combines land cover data generated for the Southwest Regional Gap Analysis project completed in 2004, the Southeast Regional Gap Analysis Project completed in 2007, the Northwest Regional Gap project, and the updated California Gap project completed in 2009. For areas of the country without an Ecological System level Gap project, data created by the Landfire Project was used. All these projects use consistent base satellite imagery, the same classification systems and similar mapping methodology allowing for the creation of a seamless national land cover map.
PAD-US VIEWER
The Protected Areas Database of the United States (PAD-US) is a national database of federal and state conservation lands. It contains the most current information about publicly held conservation lands (with conservation measures available) in the U.S. It was first published for delivery to the UNEP-World Conservation Monitoring Center’s (WCMC) World Database for Protected Areas (WDPA) in April 2009 by USGS GAP, on behalf of the PAD-US Partnership.
SPECIES VIEWER
GAPs species range and predicted habitat distribution maps display the locations on vertebrate species habitat across the country. More specifically, species distribution models based on deductive modeling of habitat associations are displayed across entire species ranges for over 2000 species. Our goal is to build species range maps and distribution models with the best available data for assessing conservation status, conservation planning, and research (e.g., climate change impacts). These models are under development and are made available as they are completed.
AQUATIC GAP VIEWER
The development of a viewer for the Aquatic GAP data is under development. Learn more about Aquatic GAP data >>
