Montana Spatial Data Infrastructure (MSDI)
The Montana Spatial Data Infrastructure is made up of fifteen “framework” geographic databases vital for making maps of Montana and understanding its geography. Seven of the databases are federally defined framework datasets and the other eight were selected as additional framework layers by the Montana Land Information Advisory Council (MLIAC).
