Montana State Library 20090118 vector digital data Helena, Montana Montana State Library ftp://ftp.gis.mt.gov/boundaries/ Data are available in ESRI's geodatabase and shapefile formats. Reservations Montana Indian 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. Reservation Boundaries were adjusted to the newest GCDB on: 04/10/09. Montana Reservation Boundaries coincident with the BLM's GCDB or the USGS 1:24,000 scale Raster Graphics. For the mapping of Montana Reservations The Base Map Service Center 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 Governmental Units Data Coordinator. en 04/10/09 publication date Complete As needed -114.959194 -104.415042 49.068887 44.890770 200427.730000 972101.020000 84139.460000 535528.720000 ISO 19115 Topic Category boundaries Montana Indian Reservations Montana Reservations Governmental Units Montana Tribal Reservations reservations tribal reservations Indian reservations MSDI Montana Spatial Data Infrastructure Indian reservations Montana Administrative Boundaries Montana 2009 None Montana Reservation data is best used in conjunction with the GCDB, or other data based on GCDB.

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. 2002-2003 Dataset copied. \\DOAITSDGIS-010\C$\mtdata\boundary\MTCounties.mdb Metadata imported.
