Where the boundary is coincident with public land survey section lines, they were copied from the BLM's Geographic Coordinate Database (GCDB). If boundary was not coincident with GCDB lines, they were digitized on screen from 1:24,000 scale Geological Survey Digital Raster Graphics (DRGs). The state boundary will change as the GCDB / Montana CadNSDI is adjusted by the BLM / Montana State Library and those data are incorporated with the Montana Spatial Data Infrastructure Administrative Boundaries & Cadastral datasets.
