1. A personal inertial surveying system comprising:

  • an inertial sensor adapted to be coupled to a person, the inertial sensor detecting motion of the inertial sensor as the person walks through a region and generating a first signal indicative of the motion of the inertial sensor;

    processing means adapted to be coupled to the person for receiving the first signal indicative of the motion of the inertial sensor and generating therefrom a second signal indicative of a position of the inertial sensor;

    a memory for storing position information related to the position of the inertial sensor;

    means for correcting the position information stored in the memory to correct for inaccuracies in the position information; and

    means for activating the means for correcting the position information, said means for activating being coupled to signals generated by the person as the person walks through the region.
