National Land Parcel Data: A Vision for the Future
activities of regional concern as well as items of national interest. As discussed in Chapter 2, this subcommittee was instrumental in creating the content data standard for a modern land parcel data model. This standard is part of the Framework Content Data Standard, which is now going through its final approval at the American National Standards Institute level. Once approved, it will become an American National Standard applicable for adoption and use at all levels of government and industry. The FGDC subcommittee is extremely active and has extensive membership from federal, state, and local agencies as well as private industry. It meets regularly and has actively promoted the use of parcel data to correspond with directions from the Presidential E-Government Initiative, Western Governors’ Association Policy on Cadastral Data, National Association of Counties, and Fifty States Initiative. In addition to the development of the content standard, the subcommittee has completed two surveys of parcel activities at the state and local levels, analyzed the role of parcel data to assist in emergency response activities, documented best practices, and developed business model templates with appropriate metrics (or measures) for assessing progress.
Some of the highlights of the most current activities include developing data element standards for energy, hurricane response, wildland fire response, and homeland security. These efforts have resulted in a series of case studies and best-practice examples that document the importance of parcel data for critical decision making. The FGDC subcommittee has also developed an extract from the Cadastral Data Content Standard to facilitate data discovery for Geospatial One-Stop. It has adopted a focus on states for the stewardship of parcel data. This resulted in a business plan template that describes how to go about setting up a parcel data development program including a framework for inventorying the current status and needs of all cadastral producers in a state. For example, Arkansas has developed the State of Arkansas Cadastral Spatial Data Infrastructure Business Plan, which is based on the FGDC Cadastral Data Core Content Standard (Arkansas Assessment Coordination Department and Arkansas Geographic Information Office, 2006, p. 7).
One recent activity that demonstrates how the subcommittee operates is its work to develop a parcel publication standard in three western states. This standard conforms to the BLM Cadastral Survey Geographic Coordinate Database. These data have been transferred to the states and are being hosted by those states. In Utah the data are used to coordinate the energy management programs and as data integration for county-produced parcel data. In return, Utah provides updated corner coordinates and parcel data for the Geographic Coordinate Data Base (GCDB). In Montana, the GCDB publication format is being used for the official Public Land Survey System (PLSS) and federal parcel representation. The state and federal agencies are using these data to coordinate further update of control and are in the process of a shared survey control project. This is an excellent example of the type of state and federal cooperation and coordination that is promoted by the FGDC and the new Office of Management and Budget (OMB) Geospatial Line of Business.
The subcommittee continues to be extremely active and has identified several specific objectives for 2006-2007. These include the following:
Develop priority business data profiles from the Cadastral Data Content Standard for cadastral data based upon national and Western Governors Association priorities.
Determine and track the status of parcel conversion to facilitate a national implementation strategy.
Maintain the Cadastral Data Content Standard, publication standards, and guidelines.
Promote the adoption of national standards by tribal, state, and local governments.
Maintain and support eastern, western, and national strategies for supporting the National Spatial Data Infrastructure (NSDI) including the U.S. offshore cadastral systems.
Provide technical assistance for implementing NSDI standards and guidelines.
Coordinate cadastral activities among participating and interested parties.
