Patent ID: 8874375

Claim:
A method, comprising: (a) receiving, with the use of a processor in a computer, a set of Cartesian data and a set of geodetic data relating to a geographic area; (b) generating, with the use of the processor in the computer, a set of control points, each control point being associated with a coordinate expressed in terms of latitude and longitude, and with a corresponding point in the set of Cartesian data; (c) determining, with the use of the processor in the computer, a plurality of sets of Cartesian coordinates for each of the control points, each of the sets of Cartesian coordinates for one of the control points corresponding to a Cartesian system; (d) determining, with the use of the processor in the computer, a deviation for a combination, the combination including a control point and the corresponding Cartesian system, the deviation being a difference between coordinates for the point associated with the control point in the set of Cartesian data and the set of Cartesian coordinates for the control point; (e) modifying, with the use of the processor in the computer, a matched set of Cartesian coordinates according to the deviation, wherein the matched set of Cartesian coordinates include at least one set of Cartesian coordinates associated with the Cartesian system that is included in the combination, but further associated with a control point not in the combination; (f) determining, with the use of the processor in the computer, a cumulative deviation for the combination by determining a sum of distances of each set of matched Cartesian coordinates modified in step (e) from the coordinates for the point associated with the control point in the Cartesian data corresponding to the matched Cartesian coordinates; (g) repeating, with the use of the processor in the computer, steps (e)-(f) for a plurality of combinations; and (h) identifying, with the use of the processor in the computer, a combination associated with a minimum cumulative deviation.
