<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Tribal Nations Reservation Boundaries were digitized from the U.S. Geological Survey (USGS) 1:250,000 scale maps adjusted to be coincident with the Bureau of Land Management's Geographic Coordinate Database (GCDB) or the USGS 1:24,000 scale Digital Raster Graphics (DRGs). Where reservation boundaries are coincident with public land survey lines, they were copied from the BLM's GCDB. If boundaries were not coincident with GCDB lines, they were digitized on screen from the USGS DRGs. Reservation Boundaries will change as the GCDB is adjusted by the BLM and those data are imported into the Montana Cadastral Data Model.

The Montana State Library and the MSDI supports a federated database approach to all MSDI layers. Montana defines a federated approach as a method that supports the integration and utilization of data from multiple data providers, while retaining the primary maintenance responsibility with the provider. Most of Montana's framework data model efforts have adopted a federated approach that leverages multiple data providers and thus multiple data maintainers. It is plausible that errors do exist and we welcome all corrections. If you do have a boundary update/correction/question please contact the Administrative Boundaries Data Coordinator.

Varies on GCDB accuracy
Reservation boundaries when coincident with the PLSS were copied from original GCDB data downloaded from the Montana State BLM Office. Based on recent observations, this GCDB data varies somewhat from what is available at the Denver GCDB LSIS site and BLM needs to coordinate to ensure one standard version of GCDB. The boundaries that are not coincident with PLSS, rivers and other topographic features, were on screen digitized from the USGS raster graphics. Discrepencies were researched when encountered, however this is not meant to represent a legal survey of Reservation boundaries.

Updated the Crow Reservation Boundary. The boundary change is a result of the Crow Boundary Settlement Act of November 2, 1994 in which a portion of the East Boundary of the Crow Reservation was relocated to the 107th Meridian (NAD 83)
2017-11-06T00:00:00
Adjusted reservation boundaries to the November 2018 CadNSDI Montana (PLSS)
2019-02-08T00:00:00
Reviewed and updated boundaries to follow the U.S. Census Bureau; Added a unique identifier (ID_UK); Aligned to the 2021 CadNSDI; Projected to NAD83 2011
2021-06-18T00:00:00
Added new fields: Tribe Number, Tribe Name, and Notes that has additional information about the Tribal Nations.
2022-03-04T00:00:00
Adjusted boundaries to align with the CadNSDI public land survey system (PLSS) where appropriate.
