PAD-US Data Manual

By Gap Analysis Project

For inclusion in PAD-US, data submissions must meet the following requirements:
- Areas meet the PAD-US definition of a protected area
- Basic attributes for each protected area are included
- Polygons (areas), not lines

<< Back to PAD-US Data Overview

Definition of a Protected Area: PAD-US is an inventory of marine and terrestrial protected areas that are defined as being:

  • “Dedicated to the preservation of biological diversity and to other natural (including extraction), recreation and cultural uses, managed for these purposes through legal or other effective means.”

The database was originally designed to support biodiversity assessments; however, its scope expanded in recent years to include all public and nonprofit held lands and waters. Most are public lands owned in fee; however, long-term easements, leases, agreements, Congressional (e.g. 'Wilderness Area'), Executive (e.g. 'National Monument'), and administrative designations (e.g. 'Area of Critical Environmental Concern') documented in agency management plans are also included. The PAD-US strives to be a complete inventory of lands in the public interest, compiling “best available” data provided by managing agencies and organizations.  

Federal, State, and non-profit data-stewards and other stakeholders assisted the PAD-US Team with the development of current requirements and continually suggest improvements during the open review periods.

New Projects --  Please contact the PAD-US Team (pad-us@usgs.gov) if you are beginning protected area data aggregation or complex analysis projects. 

PAD-US Data Dictionary --  Download the PAD-US 2.1 Data Dictionary for attribute definitions.

PAD-US Blank Schema -- Download the PAD-US 2.1 blank schema for database structure, field properties, domain codes and descriptions. 

Please note translation scripts and supporting documentation for the most current version of PAD-US (2.1) can be found in the ScienceBase collection for PAD-US 2.1. See Attached Files under that collection.
