Abstract
GIS-Based Management Interface for Water Supply Infrastructure Track: Water, Wastewater, and Stormwater Author(s): Brett Gray COMB maintains the water delivery network for five water districts in the Santa Barbara area in southern California. A GIS-based management interface was developed for network pipeline, tunnels, and reservoirs by utilizing tabular data (pipe length, strike, dip) captured from historic engineering drawings with the Traverse Tool to automate network plotting. The approach yielded on average sub-foot accuracy, and provided a framework for accuracy assessment and enhancement through field observations with Trimble GPSs. Pipe specifications, blow-off, turnout, and air-vent locations, as well as location confidence estimates were incorporated. Scans of historic "As-Built" and "Profile-and-Alignment" drawings were hotlinked to all elements to prevent information loss and facilitate maintenance and administration needs. The network was integrated with parcel, land use, utilities, ESH, and archeological layer into a single database that now serves as the primary information portal for agency personnel and is a dynamic tool for data integration, QA/QC, and administration.
