Montana Statewide Geographic Information

The Montana State Library is at the center of the State of Montana’s Geographic Information. The State Library Geographic Information Program inherits broad mandates from both the Montana Geospatial Information Act (MGIA) and the Natural Resource Information System Statute (NRIS). The Program meets these mandates through coordination, development, collection, support, distribution, and promotion of Montana Geographic Information and specifically the Montana Spatial Data Infrastructure in Montana and beyond. 


What is GIS?

A Geographic Information System (GIS) is a computer system for the capture, storing, review, and display of spatial information as it relates to the Earth’s surface. This system allows for exploration and analysis to assist in understanding patterns and relationships.
