Cadastral Technical Working Group


Cadastral Reference is the spatial grid of township, range, section, quarter-quarter lines, special surveys, mineral surveys or any line or corner established by a federal survey generally referred to as the Public Land Survey System (PLSS)


Idaho has a statewide Cadastral Reference base map that is:

  • Seamless
  • Meets accuracy needs and standards
  • Easily accessible to the GIS community and the public
  • Digital
  • Mutually beneficial to both the data producers and the data consumers
  • Continually maintained
  • Supports a multi-purpose land information system
  • Strives to comply with appropriate state and national standards, and
  • Will continue to be improved over time


Implement the vision and increase the use participating in parcel data sharing by engaging stakeholders in standards development, establish work flows and data sharing agreements and promote the benefits for data

  • Describe the current status of the Cadastral Reference and 24K PLSS across the state including statements of accuracy
  • Inventory and describe the current uses of the 24K PLSS and local cadastral reference systems for GIS mapping, especially parcel mapping
  • Document and present what has been shown to be possible at a local, regional, and state level, using examples of successful systems
  • Develop and implement, short-term, temporary procedures to assist with various GIS cadastral reference data needs while more long-term permanent solutions are being developed
  • Establish an education and outreach program supporting the vision
  • Work with BLM and local stakeholders to accomplish Cadastral Reference accuracy enhancement in priority areas
  • Where appropriate, use the information placed in the central control point database to enhance the Cadastral Reference
  • Promote legislation and public policy including developing a funding mechanism to support the vision
