Welcome to the Gap Analysis Project (GAP) Protected Areas Viewer

<< Back to Protected Areas

Administered by the U.S. Geological Survey Gap Analysis Project, the Protected Areas Database of the United States (PAD-US) is the nation’s official inventory of public open space and private protected areas.The lands included in PAD-US are assigned conservation status codes that both denote the level of biodiversity preservation and indicate other natural, recreational and cultural uses.

Many legitimate overlaps exist in the PAD-US geodatabase Combined feature class that supports this viewer (e.g. multiple Marine Protected Areas designations, Wilderness Areas over National Forests or National Parks). The viewer identifies each overlapping unit, with attributes. Refer to the geodatabase to view feature classes separately (Fee, Designation, Marine, etc.). GAP also develops a Combined file without overlaps for analyses available here.
