Version 2.0

High performance Tile and Feature services from Esri and USGS Web Mapping Services (WMS) are now available to help visualize the data in many ways.   A summary and short description of all available services is included in the data download (PADUS2_0 Layer Files Description.pdf) and from ScienceBase.  The most commonly used Services can be viewed through the PAD-US Online Map Viewer  or can be accessed and consumed by other web mapping applications using the links provided below.

The expanded multiple feature class structure of PAD-US 2.0 has increased available options to portray the PAD-US data in web services because of the separation of the "Fee" held areas from the overlapping management "Designations".  Several different types of services are now available, both in the technology used, as well as the data that is included.

Seven webmaps were produced by our partner Esri. These include: Manager Type, Manager Name, Federal Management Agencies, Protection Status by GAP Status Code, Protected Areas by Manager, Protection Mechanism Category, and Public Access. 

Each webmap contains a vector tile layer and one or more copies of feature layers or feature layer views. The three layer types allow the user to draw the map across a wide range of scales and reuse data for multiple layers. Here is how these layers work:

  • Feature Layers provide full access to the source data. Feature layers act much like a regular GIS layer but instead of storing the data on your computer it lives in the cloud on 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. The feature layers have a visible scale range set to the Esri ArcGIS Online scale range from about Counties (1:500,000) to Room (1:100) level.  You must zoom in on the map to view feature layers.


  • Feature Layer Views are just a filtered copy of a feature layer saved as a new item within the webmaps. The feature layer view points back to the original data but can be saved with different symbology and other properties. The nice part of this is, when updates are made to the original data, changes are automatically propagated to the associated feature layer views.


  • Vector Tile Layers provide cartography at scales smaller than 1:1,000,000. Feature layers don’t draw well at smaller scales, so vector tiles are used to draw the map when zoomed out past 1:1,000,000. Vector tiles don’t support an identify pop-up or legend but are very high performance.


  • The Webmap brings all the layers together with a basemap. The webmap can save copies of feature layers. This method can be used to create multiple copies of the layer to control the drawing order.


How to Get PAD-US Web Services

Below are links to Esri web services for the seven webmaps. Please note that web map services (WMS) are also available to our users.

Manager Type: Coarse level land manager description from "Agency Type" Domain, "Manager Type" Field (for example, Federal, State, Local Gov, Private).


Manager Name: Fine level manager or administrative agency name standardized for the Nation (USFS, BLM, State Fish and Wildlife, State Parks and Rec, City, NGO, etc). DOD lands shown with outline.


Federal Management Agencies: Describes Federal managers or administrative agencies by name. DOD lands shown as outline.


Protection Status by GAP Status Code: A measure of management intent to permanently protect biodiversity. GAP Status 1 & 2 areas are primarily managed for biodiversity, GAP Status 3 areas are managed for multiple uses including conservation and extraction, and GAP Status 4 areas have no known mandate for biodiversity protection.


Protected Areas by Manager: All protected areas classified by GAP Status Code protection level and manager type.




Protection Mechanism Category: The protection mechanism category including fee simple, easements, leases and agreements, and Marine Areas. Proclamation category is shown as gray outline.


Public Access: General level of public access permitted in the area - Open, Restricted (permit, seasonal), Closed, or Unknown.


Other Web Services Available

Proclamation and Other Planning Boundaries: Includes boundaries that provide additional context. Administrative agency name is standardized for the nation (DOD, FWS, NPS, USFS). Boundaries shown with outline only, as proclamation data do not depict actual ownership or management.


DOD Boundaries: Department of Defense boundaries only.


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 PAD-US 2.0 Fee feature Class only.


Federal Fee Managers (Authoritative Data): Describes Federal managers or administrative agencies by name. DOD lands shown as outline. Only Authoritative Data from Federal Data-stewards are included.


Fee Topology (Must not Overlap):  Use to identify major overlaps between agency boundaries in the Fee simple ownership layer. The assessment identifies all overlaps, those between Federal agencies only, and those between Federal and State agency boundaries.
