5 is an interpolation part, and these parts (5a).

(5b), (Function of 5 is realized by program control according to a predetermined program. θ group is a difference drawing, u31 is an interpolated difference drawing, and the dot pattern of the topographic map (1) is input. After storing it in the self-memory device (61), manually input the dot pattern of the composite drawing Uυ and store it in the self-memory device (Ill). Figure (11, old) is input using the same drawing device (3). Therefore, the position of each dot in the part of the dot pattern of the old composite map that corresponds to the dot pattern of topographic map (1) should match the position of each dot corresponding to the dot pattern of topographic map (11). However, since some deviations may occur due to the position of the image (ii1) being shifted during photoelectric setting, the dot pattern corresponding to the image (1j, old) is retrieved from the storage device, and then the alignment section ( 5b)
Perform alignment by.

For example, if the positional difference between corresponding dots is determined by the drawing difference calculation unit (5a) and the absolute value of this positional difference is added for all corresponding dots as the degree of mismatch, then this degree of mismatch is the minimum Align the alignment part (5
In b), the figure Ut+ is translated, enlarged, reduced, etc. In this way, by repeating the processes in (5a) and (5b), the alignment between FIG. 111 and FIG. 11 is performed. In this case, in order for the operator to process interactively using the CITT 101, the dot patterns of tll are simultaneously read out from the storage device (6) and the video signal of the difference is displayed on the CRT d+n. You can also.
