1. A mapping management computer system for updating geographical maps, said mapping management computer system comprising:

  • one or more non-transitory memory storage areas; and

    one or more processors in communication with said one or more memory storage areas;

    wherein said one or more processors are, collectively, configured to;

    receive operational data comprising telematics data records each identifying a historical vehicle location of a vehicle traveling along a vehicle path during one or more time periods;

    compare the operational data against stored map data to identify off-known-path telematics data records, wherein the map data comprises road data points each representing a particular location along at least one known travel path and said off-known-path telematics data records are identified from the operational data as telematics data records each corresponding to a historical vehicle location positioned at a distance exceeding a certain distance threshold from the nearest of said road data points;

    identify one or more strings of chronologically consecutive off-known-path telematics data records;

    define each of said one or more strings of off-known-path telematics data records as unknown portions of said vehicle path that do not correspond to any known travel paths;

    generate, based on said map data and said operational data, data defining a new known travel path based on said unknown portions of said vehicle path, said new known travel path representing a newly identified vehicle travel path; and

    update said map data by storing said data defining said new known travel path such that said new known travel path is reflected in one or more maps defined by said map data.
