1. Update on the South Dakota Digital Cadastral Initiative
South Dakota Association of Assessing Officers Annual Conference

Representing the Black Hills Digital Mapping Association

2. Parcel boundaries are tied to the Public Land Survey System (PLSS)
PLSS itself can be used to create parcels
Section, ¼ section, ¼ ¼ section used as legal description
Lease blocks on public lands

3. 2005 report assesses parcel data in U.S.
About 80% of the people live on 20% of the land
Total number of parcels converted to digital about 70% with most in urban areas
30% not done are in roughly 2,000 rural counties
76% of counties don’t have expertise or resources to digitize cadastral data

5. Why it’s important to put parcel data in a GIS
More informed and quicker decision making
Improved productivity/efficiency
Improved data management
Improved information access
Return-on-investment

6. Data is produced; data is distributed
Production environment – where databases are maintained and where maps and information are produced
Publication environment – where GIS data is distributed and published for users outside of the data production community

7. Reasons to create a digital statewide cadastre:
Provides:
Location information of structures (and people) for emergency purposes
Accurate inventories of natural assets – federal, state
Locational reference for administrative purposes (rules and regulations enforcement)
Standardized database for management of public lands
Base maps for planning and preliminary engineering studies
Base maps for statewide studies
Simplifies:
Coordination among state and local government
