Your City Already Publishes Its Utility Maps. Here's How Field Crews Finally Use Them — and Make Them Better.
More than 5,700 public GIS services already map America's water, sewer, and storm infrastructure — and almost nobody in the field ever opens one. Digital ROW Utilities puts them on the crew's phone, and closes the loop by sending standards-grade as-builts back.
