Patent ID: 6988049

Claim:
An apparatus for providing true geodetic coordinates of a target position (TGT) using an image database comprising: a portable personal computing device having means to accept input, and output data and commands; and, a processor configured to execute a process corresponding to said input, output data and commands, said process comprising, accepting input of true geodetic coordinates of an own position (OP); accepting input of raw coordinates of a reference point (RP); accepting input of true coordinates of RP from user, said true coordinates of RP being obtained from said image database; computing exact local magnetic declination variance between said raw coordinates of RP and said true geodetic coordinates of RP; accepting input of raw coordinates, inclination and range of said target position (TGT); computing the true geodetic coordinates of TGT utilizing the exact local magnetic declination variance; and outputting the true geodetic coordinates, inclination and range of the TGT.
