Abstract

Improving Enterprise GIS Utility Locations Using RTK and Geoprocessing Techniques
Track: Public Works
Authors: Randy Trott, James Williams

The City of Virginia Beach Department of Public Utilities (CVBPU) manages a comprehensive enterprise ESRI-based GIS to better manage its utility networks for enhanced operations management and planning. Over time, the City has constantly improved the spatial accuracies of its utility assets. One of the challenges the City faced when improving positions through GPS or surveyed locations was the need to adjust large amounts of theoretically placed features, such as water meters and sewer cleanouts, and the further need to perform these updates without introducing large amounts of Versioned edits that impact both workload and external asset management systems.
CVBPU collaborated with Timmons Group to develop workflows and processes utilizing a combination of Production Mapping tools, Geoprocessing, and Decimeter/RTK based Tablet-based GPS adjustment, that significantly reduced the level of effort associated with improving spatial locations without impacting the City's geometric network rules and asset management system validation for new/revised features.
