Geographic information and design applications at the Minnesota Department of Transportation (Mn/DOT) are numerous and diverse. Most applications and data sets have been developed independently in isolated environments. Existing design and spatial data has varying degrees of accuracy and inconsistent associations with nonspatial transportation information system (TIS) data. The GIS team at Mn/DOT's Metropolitan Division is prototyping methods to harmonize current systems. The prototype explores methodologies for collecting high-accuracy GIS data and ensuing relationships with the enterprise TIS. The proof-of-concept is demonstrated with an ArcView GIS extension created by the GIS team.
