Apparently the data had not been modivied since April 2009. The data are archived in Esri personal geodatabase format and shapefile format. 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 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. 20090410 publication date -114.959194 -104.415042 49.068887 44.890770 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 Spatial Data Infrastructure Administrative Boundaries Framework Montana MT None The Montana State Library provides this product/service for informational purposes only.

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. 2003 Reservations FID shapefile sequence number Shape Feature geometry NAME Reservation Name Perimeter Perimeter of polygon in meters Area Area of polygon in square meters.
