Contains boundaries of all restricted Tribal areas in the U.S., as requested by Tribes and Alaska Native Corporations.<\/span><\/p>

<\/p>

Field name definitions: <\/span><\/p>

<\/span><\/p>

Tribe_Name: The Tribe\u2019s official name as listed in the Federal Register or Alaska Native Corporation official name.<\/span><\/p>

NGTOC_ID: Unique number for each Tribe or Alaska Native Corporation <\/span><\/p>

State: State where the Tribe or Corporation is headquartered <\/span><\/p>

OK_to_Pub: names of lidar projects which CAN be published since the Tribe has not requested restriction<\/span><\/p>

<\/p>

Tribal boundary information:<\/span><\/p>

<\/p>

National Geospatial Program (NGP)\u2019s Tribal boundary sources are Census Bureau and BIA for CONUS and BLM data for Alaska. These 3 datasets are merged to ensure maximum coverage. NGP notifies and offers consultation based on federally recognized reservations and trust lands, Oklahoma Tribal statistical areas, and conveyed lands in Alaska. NGP does not notify or offer consultation for fee simple lands. In Alaska, NGP notifies and offers consultation to both Native Villages and Native Corporations. <\/span><\/p>

Update Process:<\/span><\/p>

New boundaries are incorporated from the Census Bureau, BIA, and BLM on a yearly basis. Note that updates to the BIA LAR dataset are temporarily suspended (since 2019) until BIA completes their consultations with Tribes. <\/span><\/p>

Tribal requests for changes to the restriction status (new restrictions or removing restrictions) are incorporated as they are received. <\/span><\/p>

Information on Federal Agency Tribal Trust Responsibility for Restricted Tribal lands:<\/span><\/p>

The USGS will not publish the lidar point cloud or digital elevation model (DEM) datasets better than 10m resolution for these areas, including high-resolution metadata such as intensity imagery. Furthermore, because all federal agencies have trust responsibilities related to federally recognized Tribes, the data for restricted Tribal lands may be shared within your agency to accomplish your mission but may not be distributed outside your agency. <\/span><\/p>

If your federal agency has a contract with a third party to do data processing on your behalf, the third party can have a copy of the restricted data, as long there is a contract requiring the third party to keep restricted data confidential, not distribute it, and delete it once finished. If your federal agency wants to share the restricted Tribal data with a third party, your agency will need to request permission from the affected Tribes directly. Data located outside the restricted Tribal boundary can be made publicly available. <\/span><\/p><\/div><\/div><\/div>", "mapName": "Tribal_Restricted_Boundaries", "description": "Contains boundaries of all restricted Tribal areas in the U.S., as requested by Tribes and Alaska Native Corporations.Field name definitions: Tribe_Name: The Tribe\u2019s official name as listed in the Federal Register or Alaska Native Corporation official name.NGTOC_ID: Unique number for each Tribe or Alaska Native Corporation State: State where the Tribe or Corporation is headquartered OK_to_Pub: names of lidar projects which CAN be published since the Tribe has not requested restrictionTribal boundary information:National Geospatial Program (NGP)\u2019s Tribal boundary sources are Census Bureau and BIA for CONUS and BLM data for Alaska.
