Feedback form is now closed.
In 2015 we initiated an inventory of our water valves originally developed from paper maps and CAD. We used existing staff with a Trimble Geo7x rover to validate valve can locations. Along the way we found anomalies and errors, but we were able to leverage this opportunity to adjust the water main geometry so they correspond with the newly validated valve points. We would like to discuss methodology and use of institutional knowledge to develop these higher quality data layers.
