1. A method, comprising:

  • collecting at least one of a trace information data, a location information using a geo positioning system (GPS) data and sensor data that is time stamped as raw data;

    preprocessing the raw data using a low-pass filter to the raw data to reduce the effect of phone orientation changes and noise and bogus changes, wherein the noise and bogus changes are one of a sudden breaks used by a vehicle, small changes in the direction while moving and mobile coordinate;

    detecting a mode of transportation to collect a transportation data, wherein the mode of transportation is at least one of a vehicle and people who are walking;

    extracting a map semantics data as a unique identifier by the semantic detection module; and

    clustering the preprocessed raw data, transportation data and map semantics data to automatically map, direct and update using a crowd sensing mechanism from a mobile device for automatic semantic identification.
