Mapping Water System Assets
Cloud Based Water System Mapping and Geographic Information Systems (GIS)
Crawford, Murphy & Tilly (CMT) provided assistance to the City of Aurora in its next phase of migrating its mapping assets to GIS, while also providing enhanced access via the Internet Cloud. The city maintained its water system mapping within an Auto CAD environment and had already completed GPS surveys of most of its fire hydrants.
A data schema was established early on based on the ESRI Local Government module to guide the conversion of AutoCAD maps to GIS. This was especially critical in converting pipe diameters in AutoCAD, which were separated by layers. Other key features included, hydrants, valves and other fittings. Quality processes were executed to ensure connectivity of the entire water network.
EFFICIENT FIELD COLLECTION
The collection process was two-fold, beginning with high-accuracy surveys of valves and transmission mains using GEOXH 6000 series collectors with VRS. Hydrants were captured in previous surveys. CMT developed a real-time data collection protocol that allowed field crews to collect all attribution data using hand-held devices such as I-Pads, tablets and smartphones. The usage of an on-line map server allowed the attribution to populate the GIS database in real time during surveys.
CMT is hosting the GIS in a map server within the Cloud environment which allows secure access for ongoing updates and management. The platform uses a registered Arc Map Server with an Enterprise SQL database allowing the Map services to be managed over the Internet.
