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.
