Abstract:
1. A method of transforming surveys of different parcels of land into a common grid coordinate system, the method comprising: providing at least two surveys, each survey including a plurality of points denoting a location on the face of the earth with the locations on the face of the earth expressed in different coordinate systems; selecting the common grid coordinate system so that a maximum difference between grid distances and ground distances is reduced to an insignificant amount over the area encompassing the surveys to be transformed; associating at least two points in each survey with points that represent the same physical location on earth in the common grid coordinate system, wherein the association of points representing the same physical points on the surface of the earth but in different coordinate systems defines a translation and rotation to be applied to each survey; and translating and rotating each survey to perform a non-scaled transformation of each survey into the common grid coordinate system.
