System and method for designating point and area in map
First Claim
1. A method of designating, in a map, a point and an area that includes the point as a basis, the method comprising steps of:
- assigning, to the point, a point-designating code that corresponds to one of regions into which the map divided according to a coordinate system;
assigning an area-designating code to the area;
defining an intrinsic code by combining the point-designating code with the area-designating code;
designating the point in the map by the point-designating code within the intrinsic code; and
designating the area in the map by the area-designating code within the intrinsic code.

Abstract
A map is divided into sections of a square of 900″×900″, each of which is further divided into blocks of a square of 30″×30″, each of which is further divided into units of a square of 1″×1″, so that a region on the map can be hierarchically designated. Each section is defined with section codes of three digits; each block is defined with block codes of three digits in accordance with the relative positional relation in the section; and each unit is defined with unit codes of three digits in accordance with the relative positional relation in the block, so that each unit can be completely differentiated with nine digits composed of those three kinds of codes. Furthermore, an area code is added to those three codes to constitute an intrinsic code, so that an area including the certain unit is also designated.

3. An area-designating system of designating, in a map, a point and an area that includes the point as a basis, the system comprising:
-
inputting means for inputting an intrinsic code that includes a point-designating code and an area-designating code, wherein the point-designating code that corresponds to one of regions into which the map divided according to a coordinate system is assigned to the point and the area-designating code is assigned to the area;
storing means for storing relation of one-to-one correspondence between the point-designating code and the point and relation of one-to-one correspondence between the area-designating code and the area; and
designating means for designating, referring to the stored relations of the one-to-one correspondence, the point in the map by the point-designating code within the intrinsic code and the area that includes the point as the basis in the map by the area-designating code within the intrinsic code when the intrinsic code is inputted through the inputting means.

inputting means for inputting an intrinsic code that includes a point-designating code and an area-designating code, wherein the point-designating code that corresponds to one of regions into which the map divided according to a coordinate system is assigned to the point and the area-designating code is assigned to the area;
storing means for storing relation of one-to-one correspondence between the point-designating code and the point and relation of one-to-one correspondence between the area-designating code and the area;
designating means for designating, referring to the stored relations of the one-to-one correspondence, the point in the map by the point-designating code within the intrinsic code and the area that includes the point as the basis in the map by the area-designating code within the intrinsic code when the intrinsic code is inputted through the inputting means; and
displaying means for reading a certain map including the designated area from a map database to display the certain map on the display along with designating the designated area in the displayed map.

5. A system of guiding a route, comprising:
-
inputting means for inputting an intrinsic code that includes a point-designating code and an area-designating code, wherein the point-designating code that corresponds to one of regions into which a map divided according to a coordinate system is assigned to a point and the area-designating code is assigned to an area that includes the point as a basis;
storing means for storing relation of one-to-one correspondence between the point-designating code and the point and relation of one-to-one correspondence between the area-designating code and the area;
designating means for designating, referring to the stored relations of the one-to-one correspondence, the point in the map by the point-designating code within the intrinsic code and the area that includes the point as the basis in the map by the area-designating code within the intrinsic code when the intrinsic code is inputted through the inputting means; and
route guiding means for setting a route that reaches a target and bypasses the designated area, and executing route guiding according to the set route.
