PURPOSE:To correct the coordinate-values of a measured map accurately in a short time and to make map-connection perfect, by connecting two corrected lot boundary points, which are located within the shortest distances from neighboring map-frame lines by a straight line. CONSTITUTION:Originally, a line, which is surrounded by common coordinate- axes, is a mathematical, theoretical, temporary line as a matter of fact. It is considered that a lot is conveniently divided by map-frame lines in preparing a map. The points, which are closest to the respective map-frame lines, are connected by the lots to be connected. The points, which intersect the map-frame lines, are made to be the mutual points. The corrected measuring points 10 and 10', 11 and 11' and 12 and 12' are connected. Thus new lot boundary lines 20, 21 and 22 are set. Then, the coordinate-axes are all obtained on the theoretical map-frame lines. An area of 120,000mm.<2> is assured on a unit of a plane table. The neighboring points become common to each other, and map connection can be made perfect. |
