The Montana Transportation Framework program uses a federated approach to combine data from various sources and integrate them into one seamless, standardized, uniformly formatted and attributed layer. Transportation data is a dynamic framework (new, upgraded and retired roads, name changes, new address ranges, etc.) and reflecting changes in statewide GIS is a challenging task. The State Library uses the federated approach for the creation and maintenance of transportation data where each data provider (tribe, federal, state, county, city, private) manage its datasets to suit their business needs and practices. The updated transportation data (features, geometries, attributes) is then forwarded to the State Library where it undergoes standardization and quality control/assurance processes. The framework then gets updated with new data and published online. Using data from local sources assures the best possible coverage across the state and ensures the best available data is centrally available. The Transportation Framework contains roads centerlines, ramps, bridges, railroads, trails and public airport features, along with address ranges and road attributes tables and relationship classes. This metadata document contains detailed descriptions of features in the Framework

The data release for geologic maps of Ravalli Group and other Mesoproterozoic Belt Supergroup strata in northern Idaho and northwestern Montana is a digital, Geologic Map Schema (GeMS)-compliant version of maps published in U.S. Geological Survey (USGS) Open-File Report 2001-438 (Boleneus and others, 2001). The new digital data include attribute tables and geospatial features (points, lines, and polygons) in the format that meets GeMS requirements. This data release presents the geologic maps as shown on the plates and captured in geospatial data for the published maps. The database represents the geology for the 2.7 million acre, geologically complex study area in eleven plates at a publication scale of 1:48,000, and two plates at a publication scale of 1:12,000. The maps cover primarily Sanders, Shoshone, Kootenai, and Lincoln Counties, but also include minor parts of Benewah and Bonner Counties. Geologic mapping was undertaken between 1979 and 1984 by ASARCO Inc. as part of their program to explore for sediment-hosted stratiform copper deposits in northern Idaho and western Montana. Geologic mapping was primarily focused on formations of the Ravalli Group, which resulted in large unmapped areas within the map boundary. In 2001 maps were scanned, georeferenced, and published by USGS (Boleneus and others, 2001).
