Abstract

A structure configuration map display system includes a controller for depicting and displaying a structure configuration map based on structure configuration map information. The system provides for searching and guidance relative to a structure designated as a target point. A display form corresponding to the structure information for the target point is determined and the display form of the target point is changed based on the results of that determination and is displayed so that a user can easily recognize the desired facility by its display form which corresponds to stored structure information. Also, the user can easily identify a facility as the desired facility and can obtain reliable guidance to that target point by the display form which indicates the type of the structure.

Claims

1. A guidance system for providing guidance information based on a structure configuration map, comprising:

storage means for storing data including structure configuration map information including configurational data for structures in the form of rows of coordinates, each row of coordinates representing a structural configuration of an individual structure, said structures including buildings and other facilities, and for storing structure information relating to the structures;

structure configuration map display control means for depicting and displaying a structure configuration map showing structural configurations of the buildings and other facilities based on the structure configuration map information stored in said storage means;

input means for setting a target point;

detecting means for detecting coordinates for the target point set by operation of said input means;

searching means for searching for a structure including the coordinates of the target point detected by said detecting means; and

display form chance means for emphasizing display of the structure, which includes the coordinates of the target point, on the displayed structure configuration map.

2. A guidance system according to claim 1 further comprising guidance processing means for outputting information relating to the structure including the coordinates of the target site.

3. A guidance system according to claim 2, wherein said input means includes a movable cursor and said guidance processing means provides information relating to the structure including the coordinates based on the speed of movement of the cursor.

4. An information guidance system according to claim 2, wherein the information relating to the structure including the coordinates of the target site includes name and address.

5. A guidance system according to claim 1, wherein said input means includes a cursor and said searching means initiates searching and said display form change means emphasizes a structure only when the speed of movement of the cursor is slower than a predetermined speed.

6. A guidance system according to claim 1, wherein an outline of the structure including coordinates of the target site is displayed with emphasis using thick lines.

7. A guidance system according to claim 1, wherein the structure including the coordinates of the target site is displayed with emphasis using color display.
