The following list contains external sources of GIS available within Montana. The data sources linked within this list all provide data at the sub-county level and may be of benefit in the development of long range planning documents or in the review of development proposals.
Montana State Library Data List: Contains comprehensive searchable and downloadable GIS data within the state. The State Library houses the state's Administrative Boundaries, Geographic Names, Hydrography, Land Cover, Structures and Transportation GIS Frameworks. These frameworks contain the most up-to-date and accurate GIS information available at the state level.
Montana Cadastral: Statewide parcels, downloadable at the county level.
Montana Census and Economic Information Center: Interactive maps, population projections, economic, public health and energy statistics.
U.S. Census Bureau: Tabular data including 2020 U.S. Census and American Community Survey Data. Data tables can be joined to downloaded TIGER shapefiles.
U.S. Census Bureau TIGER Shapefiles: U.S. Census geographies, including tracts, block groups and blocks. TIGER also maintains road and water body shapefiles, though local or state-sourced data is likely to be more accurate.
U.S. Department of Housing and Urban Development CPD Maps: Interactive mapping application.
Montana Department of Transportation Interactive Map Gallery
Center for Neighborhood Technology Housing and Transportation Affordability Index: Housing and transportation cost data for urban areas within Montana and the United States.
Montana Fish, Wildlife and Parks GIS Data: Including habitat, management areas and lake/stream data.

CTAP currently has access to ArcGIS, ArcGIS Online, ESRI Network Analyst and CommunityViz licenses that it can use to provide assistance, including:
CTAP can assist communities with the development of maps that are typically included in growth policies, displaying existing ground conditions and analyzing available data to identify trends that may not be readily apparent from raw census-level data. CTAP can also help to develop maps that portray desired future conditions, including future land use maps, maps that display and project likely outcomes based on current or proposed development patterns and maps that help to identify potential community needs and trends.
Jurisdictions wishing to amend or adopt zoning ordinances or other regulatory documents can ask CTAP to help them in the development of supporting maps. Maps can be developed at the local level and then digitized to create a readable, accessible map.
Communities in the process of developing planning documents may wish to have maps available online to support their public participation efforts. CTAP can host community web mapping resources through its ArcGIS online account.
This type of analysis helps to answer questions such as:
This type of analysis looks at the broader impacts of existing or proposed services.
This type of analysis explores existing ground conditions and draws conclusions from those conditions.
Communities can change over time. This type of analysis answers questions such as:
This looks at the existing transportation infrastructure and how it plays into the community.
