Cadastral


Cadastral data is the information about rights and interest in land. Cadastral data may also be known as real estate data, parcel information, or tax parcel information. There are many legal and historical nuances surrounding the management of cadastral information. The Cadastral NSDI/MSDI simplifies these subtleties by providing cadastral information in different components, cadastral reference (GCDB PLSS in Montana), parcels, and related coincident geometry (trust lands, stipulations, subsurface rights, boundaries, etc) which all should carry a core set of information to support identified business process needs. Montana Cadastral Framework is built primarily upon the measurement based cadastral reference of the Geographic Coordinate Database (GCDB) maintained by the BLM, with tax parcels as defined by the Dept. of Revenue. The Framework also carries an increasing amount of related and vertically integrated data such as Stewardship data, county and state boundaries, and state trust lands. Even with these additions, there is a vast amount of cadastral related data not integrated into the framework at this time.


History of Framework

The Montana Cadastral Framework is one of the oldest ongoing MSDI efforts. In 1998 established the effort by hiring a project manager to explore the concept, nd put together a project plan, to collect and maintain tax parcel data statewide, in a standardized manner. The tax parcel framework was "completed" (its really never done) in 2003. Working with our partners in the Department of Revenue (DOR) and nine counties the tax parcels are maintained, integrated into a statewide database monthly, and linked to the DOR CAMA database. However, tax parcels are only a subset of the cadastral data family, and as the data base matures, new data like state and county boundaries have been vertically integrated. There is almost an infinite amount of cadastral data such as water rights, trust lands, conservation easements, that needs to be included in the future.

Status of Framework

Theme "complete" definition - Cadastral information is never "complete" as it changes as the rights and interests on the land change. Complete for MSDI purposes implies for each individual feature class in the database, the data is complete statewide and updates from theme or sub-theme partners can be integrated with minimal processing.

Current status -Currently GCDB is complete and updated as of September, 2009; Tax Parcels are complete and updated as of August 2010; Conservation Easements are complete and updated as of August 2010; Stewardship is undergoing an update with BMSC working with the Heritage program to produce a vertically integrated database by November 2010.

Scheduled enhancements -Enhanced cadastral website in 2010/11; CAMA web-services are in place, built by DOR, however they must be contacted as to availability; continued GCDB enhancement projects - Lake County is being collected in the fall of 2010 and the Missoula County ; Missoula and Flathead counties linked to the newest GCDB in 2010 (working on Missoula now).

Theme needs:

  • Stable funding is needed for a federated approach to data integration and enhancement of the Cadastral layer. A request has been made to the legislature for general funds to support the Base Map Service Center. If this funding is not received MLIA grant funds will be necessary to continue to advance this theme. Responsible integration of a Statewide Cadastre costs approximately $100,000 per year.
  • Additional federal funds may be required to continue the GCDB enhancement program and to start collection of subsurface mineral ownership.
  • Workflow update - documentation and enhancment (see links under theme steward's corner).
