Description: 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.

Description: The Montana Incorporated Cities and Towns file geodatabase dataset represent Montana's incorporated city and town boundaries. There are 127 incorporated cities and town within the state. The Montana State Library 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. The boundary files were created based on the best available source data received the Montana Department of Transportation's Fuel Tax Layer and County Government's GIS Programs. The Fuel Tax layer was adjusted to the most current version of the Montana GCDB and Cadastral Parcels. Digital data used as a base layer to adjust these boundary files were the best available source at the time: Cadastral (parcel lines), Geographic Coordination Data Base (GCDB), National Agriculture Imagery Program (NAIP) Imagery. It is plausible that errors do exist and we welcome all corrections. If you do have a correction to a boundary please contact the Administrative Boundaries Data Coordinator.

Description: The Montana Transportation Framework is a statewide, standardized, database of road centerlines in the State of Montana. The Montana Transportation Framework is part of the Montana Spatial Data Infrastructure (MSDI). Through a federated approach, the Framework aggregates tribal, county, city, and federal road centerline data into a standardized database. The Transportation Framework contains roads centerline feature geometry, along with address ranges and other attributes.Individual data providers datasets have not been edgematched. As a result, gaps, overlaps, and duplicate features are present in the dataset.

Description: Feature class of Montana State Boundary was created to be coincident with the Montana County Boundaries, GCDB, and Cadastral Parcel Boundaries. 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.
