1. A method of storing and using geopositioning information comprising:

  • storing geopositioning imagery data and imagery information;

    storing extracted information derived from the imagery data;

    storing heritage information relevant to the computation of the extracted information;

    receiving and storing new imagery data;

    performing a pixel measurement process to produce additional extracted information and additional heritage information;

    storing the additional extracted information and additional heritage information;

    performing triangulation using all relevant accumulated information in the form of stored imagery data, imagery information, extracted information and heritage information;

    storing updated imagery information, extracted information, and heritage information resulting from the triangulation as additional accumulated information;

    performing photogrammetric calculations using the updated heritage information and imagery information from the triangulation to generate updated extracted information for points not included in the triangulation; and

    storing the resulting updated extracted information.
