Abstract:

These data are from the Montana reservations database that was available on the Montana State Library web site at the end of 2015.

Montana Indian Reservation Boundaries were digitized from the U.S. Geological Survey (USGS) 1:250,000 scale maps and were adjusted to be coincident with the Montana CadNSDI Public Land Survey System databaseor the US Geological Survey 1:24,000 scale Digital Raster Graphic (DRG) images of topographic maps. Where reservation boundaries are coincident with public land survey lines, they are coincident with the CadNSDI. If boundaries were not coincident with GCDB lines, they were digitized on screen from the USGS DRGs. Reservation Boundaries will change as the CadNSDI is adjusted. Reservation boundaries were adjusted to the current CadNSDI on June 17, 2015.

Title: CadNSDI Public Land Survey System Database
Online linkage: https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/Cadastral/PLSS
Source contribution:: This is the source of all reservation boundary lines that follow Public Land Survey lines. The CadNSDI data were derived from the BLM Geographic Coordinate Database (GCDB) and the reservation boundary lines were originally selected from the GCDB. The CadNSDI is a successor to the GCDB and is now the source for adjustments to data that follow public land survey lines.

Source scale denominator: 24000
Source contribution:: Montana Indian Reservation lines that do not follow Public Land Survey lines were screen-digitized from these images.

Process step:

Montana Indian 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 PLSSS, rivers and other topographic features, were on screen digitized from the USGS rastergraphics. Discrepencies were researched when encountered, however this is not meant to represent a legal survey of Montana Indian Reservation boundaries.
