摘要

PROBLEM TO BE SOLVED: To allow arbitrary coordinates from a TS to be precisely converted to world coordinates when using the TS and a GPS to give world coordinates of reference points.;SOLUTION: A device for acquiring world coordinates of a cadastral survey map includes a coordinate value accepting part 1 for accepting inputs of arbitrary coordinates and world coordinates of all pairs of two reference points out of four reference points, a distance operation part 2 for calculating at least coefficients of an conditional expression relating to distances between pertinent reference points from coordinate values accepted by the coordinate value accepting part, an included angle operation part 3 for calculating at least coefficients of a conditional expression relating to included angles between segments connecting respective pairs of reference points from the coordinate values accepted by the coordinate value accepting part 1, a correction value generation part 4 for generating correction values as a solution of an observation equation from the coefficients calculated by the distance operation part 2 and the included angle operation part 3, and a storage part 5 for storing the correction values generated by the correction value generation part 4.;COPYRIGHT: (C)2007,JPO&INPIT
