Abstract
Cobb County, Georgia, Enterprise Transportation GIS Network: CobbETRANS Track: Transportation Author(s): Lynn Biggs, Pete Estes Cobb County oversees Georgia's largest county-owned road network. A seamless, standardized, working transportation GIS database is required so that county services can be provided efficiently to Cobb's residents. The county had developed three different street centerline files--one for DOT asset management and another for E911's computer aided dispatch system. Because of the complexity and cost associated with maintaining multiple centerline road layers, the goal of CobbETRANS is to leverage these by converting them to the third centerline layer that was derived from Cobb's new orthophoto base map. Cobb's transportation GIS was taken to a new level by developing a geometric network for future paratransit and senior services trip planning and E911 incident location and dispatch routing. CobbETRANS is Cobb's first database developed as an enterprise geodatabase. This paper will highlight the planning, procedures, and pitfalls that occurred while developing and implementing an extensive Enterprise GIS-Transportation model.
