摘要：	An investigation of South Dakota Department of Transportation (SDDOT) location referencing practices and procedures identified the functional requirements of and specific changes that should be implemented to establish a standard location referencing system that will address SDDOT data integration needs. Critical elements of the proposed location referencing system include a relational database to enhance data access and data management capabilities, coordinate transformation interfaces to enable integration of data from diverse referencing systems, and time data attribute to enable historical data management. The study identified 13 discrete location referencing systems in use, provided insight on data sharing needs and uses of location-reference data, and provided a basis for recommened changes that should be implemented to address SDDOT data integration needs. Implementation alternatives were investigated, and a recommended implementation strategy was defined. A relational DBMS was identified as the preferred DBMS based on comparative analyses of system functionality and life cycle cost and SDDOT institutional constraints.
