Things You Can Do with PAD-US Web Services:
There is a lot of information contained in PAD-US. The different web services listed above were created from PAD-US to provide multiple ways of portraying the data. This enables the development of applications capable of supporting several diverse uses. This page lists some of Things You Can Do with PAD-US Web Services and includes service descriptions and access links. The multiple feature class structure separates 'Fee' held areas from management 'Designations' that often overlap. A good way to get started is by determining if 'Fee' only services are best suited for your application versus those developed from the 'Combined' PAD-US Inventory that includes fee simple parcels, management designations, and easements.
- Explore the U.S. protected areas network
- Access lands owned (or held) in fee
- Bring it all together with combined inventory
- View conservation or recreation measures
- Add planning boundaries for context
PAD-US web maps often contain vector tile layers, one or more feature layers, and feature layer views. Using these three types of layers allow users to create mapping applications across a wide range of scales for numerous different use cases. Here is how these layers work:
- Feature Layers provide the full source data. They act much like a regular geospatial layer but instead of storing the data on your computer it lives in ArcGIS Online. Feature layers allow for dynamic interaction with the data, changes can be made to the symbology, filters can be applied to the data, as well as some types of analysis.
- Feature Layer Views are a filtered copy of a feature layer saved as a new item within the ArcGIS Online. They provide pointers back to the original data but can be saved with different symbology and other properties. When updates are made to the original data, changes are automatically propagated to the associated feature layer views allowing URLs to remain the same as new versions of PAD-US are published.
- Vector Tile Layers provide cartography at smaller scales. Feature layers don’t draw well at smaller scales, so vector tiles are used to draw zoomed out map products. Vector tiles don’t support an identify pop-up or legend but are very high performance.
- Web Maps brings all the layers together with a basemap. The web map can save copies of feature layers. This method can be used to create multiple copies of the layer to control the drawing order.
1. Explore the U.S. protected areas network
The fully combined PAD-US inventory represents the complexity of the U.S. protected areas network. Explore the Protection Mechanism Category layer to gain a better understanding about the components of the PAD-US database (Fee lands, designations, easements, marine areas, proclamation, or other planning boundaries) to choose the best service for your application.
Protection Mechanism Category: Shows categories of land tenure for all protected areas, and also includes marine ares, proclamation, and other planning boundaries from the combined PAD-US inventory.
The Protection Mechanism Category illustrates the PAD-US “Category” field, representing lands held in the public interest by fee simple ownership (the most common way lands are owned); Executive, legislative, and administrative (i.e. found in management plans) designations that often overlap fee or private lands; easement interests on public or private land, leases and agreements between public agencies; and marine protected areas or those managed for mineral or energy development. Proclamation and other planning boundaries (e.g. Military Lands) are included for context and shown as gray outline as internal interests are not depicted.

2. Access lands owned (or held) in fee
PAD-US Fee only layers - No designations, easements, marine areas, or proclamation boundaries.
PAD-US allows users to choose services that display the fully combined PAD-US inventory or only the ‘footprint’ of lands held in fee simple for open space public interests from the PAD-US Fee feature class. Two options are available for users primarily interested in management jurisdiction (for example, base map providers or the recreation and emergency management communities), the "Federal Fee Managers" includes federal lands only, while "All Fee Managers" also includes state, local government, nonprofit, and other fee owned lands (data gaps exist below the state level). The services do not include easements, marine areas, proclamation or other planning boundaries, management designations (e.g. Wilderness) that often overlap federal, state, or private inholdings.
Fee Managers: Fine level manager or administrative agency name standardized for the Nation (USFS, BLM, State Fish and Wildlife, State Parks and Rec, City, NGO, etc) from the “Manager Name” field. Includes fee simple parcels (where available) from the PAD-US Fee feature Class only. Tribal Areas included for context.
This service does not include designations that often overlap state, private or other inholdings (see Manager Name service for combined layer - Fee+Designation+Easement).
Federal Fee Managers (Authoritative Data): Describes federal administrative agencies from the “Manager Name” field. Includes fee simple parcels (where available) from authoritative data sources from PAD-US Fee feature class only.
This service does not include designations that often overlap state, private, or other inholdings (see Federal Management Areas for combined layer - Fee+Designation+Easement). DOD Military Lands (from Proclamation feature class) lands shown as an outline since internal land ownership is not represented (but implied Federal). Tribal Areas included for context.
PAD-US is the official National Geospatial Data Asset for aggregated U.S. protected areas data, developed by USGS in collaboration with the FGDC Federal Lands Working Group (FLWG). PAD-US is the best available U.S. aggregation of federal land ownership, easement interest, and management designations, as well as state, local and nonprofit data on protected areas. PAD-US is an appropriate data source for questions related to more than one agency; agencies are always the official source of their land data and some update more frequently than PAD-US. Visit PAD-US Data Stewards Reports to view graphics and generate reports about the completeness, capacity, last update date, agency information, and contacts for Federal, State, and NGO PAD-US Data Stewards.

3. Bring it all together with combined inventory
PAD-US Combined layers - Fee + Designation + Easement + Marine + DOD Military Lands (from Proclamation feature class).
The web services below illustrate the full PAD-US inventory with fee simple parcels (where available), easement interests, marine areas, DOD Military Lands (from Proclamation feature class), and overlapping management designations. Note - Designations often overlap federal, state, or private inholdings.
The new PAD-US Viewer includes a split screen option for users to compare layers. For example, place the “Federal Fee Managers - Authoritative Data” service layer in the left panel and combined “Federal Management Agencies” service that includes designations and easements on the right.
Manager Type: Broad categorization of manager levels, for general depictions of who manages what areas from the combined PAD-US inventory.
Includes coarse level land manager description from "Agency Type" Domain, "Manager Type" Field (for example, Federal, State, Local Gov, Private) from the combined inventory (includes Fee+Designations+Easements). DOD Military Lands shown with an outline as internal interests are not defined (but assumed Federal).
Manager Name: Categorization by name, with detailed federal managers and generic state/local/other managers from the combined PAD-US inventory.
For example, names include USFS, BLM, State Fish and Wildlife, State Parks and Rec, City, NGO, etc. from the combined inventory (includes Fee+Designations+Easements) with descriptions from the "Agency Name" Domain, "Manager Name" Field. DOD Military Lands shown with an outline as internal interests not defined (but assumed Federal).
Federal Management Agencies: Use to depict federal agency land managers or administrators (no state, local, or nonprofit lands) by name from the combined PAD-US inventory
This service includes Fee+Designations+Easements (Designations often overlap private or other inholdings). DOD Military Lands are shown with an outline as internal interests are not defined (but assumed Federal).

4. View conservation or recreation measures
PAD-US Combined layers - Fee + Designation + Easement + Marine + DOD Military Lands (from Proclamation feature class).
Users interested in conservation assessments are encouraged to use the Protection Status (by GAP Status Code) or Public Access services below, as management restrictions associated with designations are key and the Combined layer is required.
These layers include overlaps - click on an area to view attributes associated fee lands and designations in the PAD-US Viewer. A ‘flat’ vector analysis file used to prioritize overlaps (by GAP Status Code, Public Access, and geodatabase load order) for summary statistics is available to download from the PAD-US Statistics and Reports web page.
Protection Status by GAP Status Code: A measure of management intent to permanently protect biodiversity for all lands and marine areas in the combined PAD-US Inventory.
GAP Status 1 & 2 areas are primarily managed for biodiversity, GAP Status 3 areas are managed for multiple uses including conservation but where extraction may be permitted (for example, logging, or mining), and GAP Status 4 areas have no known mandate for biodiversity protection (such as private land, protected areas with unknown management objectives, etc.).
Protected Areas by Manager: All protected areas classified by GAP Status Code protection level and manager type.
Public Access: General level of public access permitted in the area - Open, Restricted (permit, seasonal), Closed, or Unknown from the combined PAD-US Inventory (local parks data gaps exist).
This measure is largely assigned categorically by PAD-US “Designation Type” and not all areas have been locally reviewed. In addition, many local park data gaps exist in some states. See inventory completeness by State at: PAD-US Data Stewards Reports

5. Add planning boundaries for context
Proclamation and Other Planning Boundaries: Includes boundaries that provide additional context by administrative agency name (for example, DOD, FWS, NPS, USFS) shown with an outline as internal ownership is not represented.
