The Montana Cadastral Framework provides a digital representation of the written legal description of taxable parcels and non-taxable parcels, or land ownership, as defined in the Montana Department of Revenue's (DOR) Computer Assisted Mass Appraisal database (CAMA) The non-taxable parcels may include public lands (federal, state, local governments, etc.), tribal lands in USA or tribal trust, and other exempt property such as church owned property. The boundaries of aliquot parcels are built on the Bureau of Land Management’s Geographic Coordinate Database (GCDB). The non-aliquot parcels (parcels based on bearings and distances) are/were created through the use of coordinate geometry (COGO) and/or original digitization of paper and Mylar maps or deeds and still primarily reside on a GIS base.
