Online linkage: https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/AddressStructures/

Abstract:

The Montana Structures/Addresses Framework is a statewide spatial database of structure and address points in the State of Montana. The Montana Structures/Addresses Framework is part of the Montana Spatial Data Infrastructure (MSDI). The goal of the Montana Structures/Addresses Framework is to have a routinely updated statewide database of addresses and selected theme-specific structure point data (e.g., schools, airports, fire stations, etc.).

Through a federated approach, the project integrates structure and address point data from local, tribal, state, federal and private data providers into a standardized database. For more information about the included datasets, see Source information in the Data Quality Information section of this document or the metadata table in the database.

Purpose:

To provide a standardized repository for structures and address data. The Structures/Addresses Framework is designed to support a wide range of uses for a statewide, standardized structures layer, from emergency response, to planning, to natural resource studies.
