U.S. Geological Survey Gap Analysis Project (GAP) Analytical Database

The Gap Analysis Project (GAP) Analytical Database represents a synthesis of three core datasets for the conterminous U.S. Specifically 1) the GAP/LANDFIRE National Terrestrial Ecosystems_2011; 2) the Protected Areas Database of the United States (PAD-US) 1.4; and 3) the Species Ranges and Habitat Distribution Models for all terrestrial vertebrates. This database provides a mechanism to effiiently obtain summary statistics of those for a variety of spatial extents, including US states, US counties, Landscape Conservation Cooperation Network Areas, EPA's Level III-IV Ecoregions of the United States, and Level I-III Ecoregions of North America and 12-digit (6th level) hydrologic units.

This is an experimental collection that implements an information model for biogeographic information. We are building this on the conceptual foundation from the Global Change Information System. We are using the Biogeographic Information System, accessed via the ScienceBase API, as a basis to drive an experimental new map interface (National Biogeographic Map) and a developing iterative report concept (National Biodiversity Assessment).

Protected Areas Database of the United States (PAD-US) 2.1 - World Database on Protected Areas (WDPA) Submission (ver 1.1, April 2021)

The United States Geological Survey (USGS) - Science Analytics and Synthesis (SAS) - Gap Analysis Project (GAP) manages the Protected Areas Database of the United States (PAD-US), an Arc10x geodatabase, that includes a full inventory of areas dedicated to the preservation of biological diversity and to other natural, recreation, historic, and cultural uses, managed for these purposes through legal or other effective means. The PAD-US is developed in partnership with many organizations, including coordination groups at the [U.S.] Federal level, lead organizations for each State, and a number of national and other non-governmental organizations whose work is closely related to the PAD-US.

The Protected Areas Database of the United States (PAD-US) is the official inventory of protected open space in the United States. With over 3 billion acres in thousands of holdings, the spatial data in PAD-US include public lands, overlapping management designations, and Marine Protected Areas held in trust by national, state, some local governments, and by some nonprofit conservation organizations.

PAD-US 2.1 Fee Overlap Assessment

As an aggregated inventory, PAD-US contains thousands of spatial data sources integrated into one combined database. The policy of USGS is to integrate agency source data boundaries “as is” and translate attributes into the PAD-US format. Boundaries created by a specific agency or data steward may not fully align with those of another, creating GIS topology errors (mostly minor boundary discrepancies) associated with fee parcel ownership. In addition, more than one agency may submit an area for PAD-US without complete or accurate attributes to differentiate the fee owner and land manager.
