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 map data and operational data, said map data comprising data defining a plurality of known travel paths each representing a constructed physical surface along which a vehicle may travel, and said operational data comprising vehicle telematics data indicative of one or more vehicle dynamics for at least one vehicle during one or more time periods;

    identify, based on said operational data, a vehicle path traveled by said at least one vehicle during said time periods, wherein said vehicle path represents the dynamic location of said at least one vehicle during said time periods;

    identify, based on said map data, road data points each representing a particular location along at least one of said known travel paths;

    identify, based on said operational data, telematics data records indicating the location of said vehicle at various points along said vehicle path;

    identify off-known-path telematics data records indicating that said vehicle is 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 of said 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 new constructed physical surface along which a vehicle may travel; 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.
