Description: The Montana Department of Revenue (DOR) maintains the database of Tax Increment Financing Districts. Attribute information including levy districts and dates comes directly from them. The MSL acts as the point of contact on these boundaries for editing, schema changes, maintenance, web services and distribution. These boundaries were created based on the best available source data received from the Montana DOR or from the local governments: Legal Descriptions, GIS Files, Source Maps, or where data sources were not available the Montana Cadastral GIS Data was used. Digital data used as a base layer to create these boundary files were the best available source at the time: Cadastral (parcel lines), Geographic Coordination Data Base (GCDB)/ CadNSDI, National Agriculture Imagery Program (NAIP) Imagery, and 1:24,000 USGS Topographic Maps. All of these base layers can be found at the following website for download: https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/

Description: The Montana Voting Precincts have been updated as part of redistricting in 2023. Not every county had updates following the creation of the new Montana legislative districts. This dataset will be updated as new voting precincts are obtained. The Montana voting or election precincts for the entire State of Montana were originally obtained from the local county offices by the Montana Department of Commerce through an FY2019 Montana Land Information Act (MLIA) Grant. The contractor used data (obtained from the counties) to digitize voting district boundaries following the recommendations of the U.S. Census Bureau Redistricting Data Program. Source data may be GIS digital data or manually digitized from maps. Key fields included 2-digit state FIPS, 3-digit county FIPS, Precinct Number, Precinct Name, County Name, and Data Date. Voting Precinct boundaries were aligned to MSDI administrative boundaries, PLSS, and parcels and projected to the Montana State Plane. According to MCA 13-3-101 the governing body of each county shall establish a convenient number of election precincts, equalizing the number of electors in each precinct as nearly as possible. According to MCA 13-3-102 the county governing body may change the boundaries of precincts, but not within 100 days before any primary or between a general election and the primary for that election. When the changes are required to make precinct boundaries conform to legislative district boundaries following the adoption of a districting and apportionment plan under Article V, section 14, of the Montana constitution or other district boundaries changed by the districting and apportionment plan, the changing of precinct boundaries must be accomplished within 45 days of the filing of the final plan.

Description: Tribal Nations 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.
