Patent ID: 7440610

Claim:
An apparatus providing true geodetic coordinates of a target position (TGT) using an optical stereo image database comprising: a portable personal computing device (PC) having means to accept input and commands, means to output, a memory means, and means to display a set of optical stereo images, side by side, from said optical stereo image database, comprising a first image and a second image wherein said optical stereo image database is a Digital Point Positioning Database (DPPDB); and, a processor configured to maintain said optical stereo image database comprising at least one set of said stereo images with corresponding geodetic data, and to execute a process corresponding to said input and commands, said process comprising, accepting input of geodetic coordinates of an own position (OP); extracting the set of stereo images centered around said OP from said stereo image database and storing said images in said memory means; displaying said stereo images via said display means and displaying a first marker corresponding to the OP on each of the first and second images; accepting input of the true geodetic coordinates target position (TGT) on said first stereo image and displaying a second marker corresponding to the TGT on the first image; autocorrelating and displaying said second marker corresponding to the TGT on said second stereo image; receiving approval of the selection of TGT; computing the true geodetic coordinates and elevation for the TGT including correcting said geodetic data from the optical stereo image database for local magnetic declination variance; outputting the true geodetic coordinates, inclination and range of the TGT.
