A map of an entire region is divided into sections of a square of 900", each of which is further divided into blocks of a square of 30", each of which is further divided into units of a square of 1", so that a region on the map can be hierarchically designated. Each section is defined with section codes of three figures; each block is defined with block codes of three figures in accordance with its relative positional relation in the section; and each unit is defined with unit codes of three figures in accordance with its relative positional relation in the block, so that each unit can be completely differentiated with an intrinsic code of nine figures composed of those three kinds of codes. As to the section code composing the intrinsic code corresponding to the predetermined region, moreover, a number of significant digits is reduced by assigning a lower number in the code system, so that the manual operations of inputting the intrinsic code of the predetermined region can be lightened.

[ What is claimed is:] [1.] A method for designating points on a map, comprising:defining a map grid with a predetermined arrangement of units of measurement;assigning an intrinsic code to each of said units of measurement in a predetermined hierarchical manner so that a point on said map grid may be specified by a corresponding intrinsic code in a manner that minimizes said corresponding intrinsic code,defining facility intrinsic codes individually corresponding to predetermined map target facilities by a code system other than said intrinsic codes so that said predetermined facilities can be specified by said facility intrinsic codes, andindividually defining said facility intrinsic codes for said predetermined map target facilities with low resolution intrinsic codes so that said predetermined facilities can be specified by combinations of said low resolution intrinsic codes and said facility intrinsic codes.
