MSDI Framework Administrative Boundaries
Abstract The Tribal Nations Reservation Boundaries in Montana 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.Tribal Nations Reservation Boundaries in Montana coincident with the BLM's GCDB or the USGS 1:24,000 scale Raster Graphics. The dataset now includes Off Reservation Trust Land from the U.S. Census Bureau that has been supplemented with Montana Department of Revenue owner parcels.
Purpose For the mapping of Tribal Nations Reservations in Montana
Supplemental Information 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.
Montana Tribal Nations Reservation data is best used in conjunction with the GCDB, or other data based on GCDB.
