Abstract:
Database of Montana Counties created to be coincident with the Montana Cadastral Parcel Boundaries. Where county boundaries are coincident with public land survey section lines, they were copied from the BLM's Geographic Coordinate Database (GCDB). If boundaries were not coincident with GCDB lines, they were digitized on screen from 1:24,000 scale Geological Survey Digital Raster Graphics (DRGs). County Boundaries will change as the GCDB is adjusted by the BLM and those data are imported into the Cadastral Data Model. Adjusted to the newest GCDB: 10/05/09

Source contribution:
County lines that do not follow Public Land Survey lines were screen-digitized from these images.
Process step:
County boundaries when coincident with the PLSS were copied from origianl 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, howverer this is not meant to represent a legal survey of Montana county boundaries
