Viewable base map files are available for all of Missoula County. These files are each a single township in size (36 square miles) except for the Missoula Urban Area (T13N, R19W). This area is mapped one section (1 square mile) at a time.


Digital map data is available for download at The base map files are in AutoCAD R14(c) format. All files are compressed using PKWARE's PKZIP program.

Files with the .EXE extension contain data in AutoCAD .DWG format. Files with the .ZIP extension contain data in AutoCAD .DXF format created using AutoCAD's DXFOUT command.

The base map data was projected in NAD27 format up through July 28, 2000. As of July 31, 2000 the data is projected in NAD83 format.
