Systems and methods for determining an accurate location of a signal's source of transmission. The methods involve: demodulating a detected carrier signal modulated with a Pseudo Noise (“PN”) code sequence to obtain an original information-bearing signal therefrom; computing time delay offsets using correlations of PN code windows for each symbol of the original information-bearing signal; determining a high accuracy Time Of Arrival (“TOA”) of the detected carrier signal using the time delay offsets; and using the high accuracy TOA to determine an accurate location of the original information-bearing signal's source of transmission.

A graphical user interface may provide a digital map that includes digital marks for utility lines and excavation boundary. To determine the location information of a ground mark, a computing server may receive an image of a street view of a site and identify one or more ground marks from the image. The computing server may receive geographic information system (GIS) data, which records surveyed location information of benchmarks at the site. The computing server may identify, using an object recognition algorithm, pixels in the image of the street view that correspond to the benchmarks recorded in the GIS data. The computing server may determine, based on relative distances between the pixels that correspond to the benchmarks and the ground marks, location data of the ground marks. The computing server may transmit the location data for display in a digital map that includes digital marks corresponding to the ground marks.

The disclosure includes embodiments for a location data correction service for connected vehicles. A method includes receiving, by an operation center via a serverless ad-hoc vehicular network, a first wireless message that includes legacy location data that describes a geographic location of a legacy vehicle. The method includes causing a rich sensor set included in the operation center to record sensor data describing the geographic locations of objects in a roadway environment. The method includes determining correction data that describes a variance between the geographic location of the legacy vehicle as described by the sensor data and the legacy location data. The method includes transmitting a second wireless message to the legacy vehicle, wherein the second wireless message includes the correction data so that the legacy vehicle receives a benefit by correcting the legacy location data to minimize the variance.
