| Value | Description |
|---|---|
estimated |
Estimated location associated with work zone activities and lane closures. An estimated measurement may be based on an approximation of a location referencing method (e.g., lat/long or milepost), for example: a point relative to a posted milemarker, point on a map, or GPS device that provides less than centimeter accuracy. |
verified |
Actual reported information about work zone locations. Actual location is typically measured by a calibrated navigation or survey system to centimeter accuracy (six decimal places for latitude and longitude). |
