Electronic mapping of land ownership is often
associated with local government agencies at the municipal or county level.
Parcel data is essential for supporting public sector land management and
taxation operations. Other public agencies also perform this task but may be
less visible. The Minnesota Department of Transportation (Mn/DOT) is one of them
actively creating and maintaining high accuracy parcel maps of the lands it
administers for transportation purposes. To support its land management needs,
Mn/DOT conducts in-depth real estate title research to define parcel holdings,
performs field surveys to define and mark new boundaries, and prepare documents
showing detailed measurements with corresponding information defining new
parcels for right of way acquisition. Many similar characteristics can be
identified with those mapping parcels outside the highway right of way, although
some differences do occur.
Standardization of all parcel entities leading to a more uniform cadastral system will more readily support LIS applications. Being both a customer and a producer of parcel map data, Mn/DOT has a unique opportunity to facilitate the exchange of parcel mapping standards between advanced sectors of the state and those looking to get started in parcel mapping. Exploring ways to open access to Mn/DOT's parcel data while improving the communication of methods that are used to create the data is expected to help the agency meet its business needs and improve support for its customers. Success in these areas will at the same time help to advance a National Spatial Data Infrastructure.
