DDOT Street Spatial Database: A Use Case for UNETRANS
Track: Transportation
Author(s): Minhua Wang, Ali Fatah

DDOT's street database system is moving into an enterprise system architecture, namely the Transportation Enterprise Asset Management System (TEAMS), in which GIS is a key component. The roles that GIS play in TEAMS are not only as the software platform for mapping but also as the data integrator, the common denominator, for enterprise data integration. DDOT GIS division staff evaluated Esri's UNETRANS data model. The new street spatial database model used UNETRANS as the foundation and took roadway segment and intersect point as the basic geometry elements for the data model, constructed a four-tier data structure to cover street roadway network and assets, and applied Esri's geodatabase topology technology to create shared geometry, thus simplifying spatial data maintenance. This presentation will demonstrate the completed project including street spatial data model, topology setting, custom rule setting for spatial data maintenance, and the complete DDOT street spatial database.
