While the GS50+ units will be used to periodically update the City’s inventory, the storm sewer project should be completed by April 2003.
To plot and gather utilities data, workers are mapping all manholes, incorporating and labeling them in ESRI’s ArcView, using the GS50+ base station (mounted atop a water tower and controlled remotely) and a Microslate pen tablet. Data such as inverts, pipe size and pipe condition is being recorded. To track data through the thick tree canopy in the area, the Public Works Department is using the GS50’s MaxTrak tracking technology.
Because the GPS signal used with the GS50+ is easily integratable with other third party vendor items, staff members will have the flexibility to incorporate their Leica and ESRI products with other GPS/GIS products of choice for future projects.
In 2003, the City of Rock Island plans to use the GS50+ units to collect road sign and tree inventory, as well as lay out and mark utilities prior to future construction. Plans are also in the works to incorporate their GPS signal into wireless Internet service for use by other departments in the municipality. A wireless network solution is expected to be in place by 2004.
The Public Works Department is working to get other Quad Cities (Rock Island and Moline, Illinois, and Davenport and Bettendorf, Iowa, all USA) to subscribe to using GPS technology. (The Quad Cities area consists of) Currently, Rock Island is the only city in the area to have a base station installed and to extensively use GPS/GIS technology.
