Napa, Calif., is mapping its streets with a car-mounted camera system similar to the ones used to create Google Street View images. When the project is complete, the city will have a detailed, GPS-tagged record of its sidewalks, trees, light poles and other features. The hope is that the database will help the city maintain its infrastructure. "If we can manage our assets in the field more closely, it makes us much more efficient," said Phil Brun, deputy director of public works for operations. "Rather than hop-scotching all over town to fix potholes, we can find clusters."
