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.

We would like to discuss methodology and use of institutional knowledge to develop these higher quality data layers.
