The input unit 3 is input means for inputting processing contents in the apparatus such as setting of search conditions, and for example, a keyboard, a mouse, and the like are used. The main storage unit 4 is connected to the CPU 2. The main storage unit 4 is a storage unit that stores a map search control program and the like recorded on a recording medium, and uses, for example, a hard disk device.

A display unit 5 is connected to the CPU 2. The display unit 5 is a display unit that displays a map or the like as an image, and for example, a liquid crystal display or the like is used.
Further, a printing unit 6 is connected to the CPU 2. The printing unit 6 is one of output units for printing a map or the like displayed on the display unit 5 as an image, and a printer or the like is used. Further, an auxiliary storage unit 7 is connected to the CPU 2. Further, a CD-ROM 8 is connected to the CPU 2 via a driver. The CD-ROM 8 is a recording medium on which a map search control program is recorded.

FIG. 2 shows the structure of the control program recorded on the CD-ROM.

As shown in FIG. 2, the control program recorded on the CD-ROM 8 is a GUI (Graphical User Int.)
(Erface) control unit 10, map display control unit 20, object control unit 30, and search control unit 40. The GUI control unit 10 controls the input unit 3 to display a button or the like on the display unit 5 and to perform a map display, a search condition setting, or a printing process in accordance with an operation of the button or the like. The map display control unit 20 controls reading of map data and display of map data.

The object control section 30 controls reading of object data and display of objects. Here, “object” means a search target displayed on a map. This object is not limited to a point-like object such as a person or the location of a store, but also includes a two-dimensional object such as a linear object such as a road or a track, and a facility having a vast site. The search control unit 40 controls setting of search conditions and search calculation.

This control program is stored in the main storage unit 4 and used for a map search process. At the time of the map search processing, map data for image display may be appropriately read from the CD-ROM 8 as necessary, or the map data may be stored in the auxiliary storage unit 7 and the auxiliary storage unit may be appropriately stored. 7 may be read.

Next, the operation of the map search device 1 and a map search method will be described.

FIG. 3 is a flowchart showing the operation of the map search device 1 and the map search method. Step S in FIG.
10 (hereinafter simply referred to as “S10”; the same applies to other steps), map data is read, and a map is displayed on the screen of the display unit 5. Then, the process proceeds to S12, where the object data is read, and as shown in FIG. 4, the objects 61 to 63 are superimposed and displayed on the map 51 displayed on the screen of the display unit 5.

The object 61 indicates the location of a person or a store, and is set as a coordinate point in the two-dimensional coordinate system set on the map 51, and the display position is specified. The object 62 indicates a train line, and is set as a line segment connecting a plurality of coordinate points in the two-dimensional coordinate system set on the map 51, and the display position is specified. The object 63 indicates a road on which the vehicle passes, and is set as a line segment connecting a plurality of coordinate points in a two-dimensional coordinate system set on the map 51, similarly to a track, and a display position is specified.

Then, the flow shifts to S14, where it is determined whether a search condition has been set. The setting of the search condition means selection of a plurality of search targets and search methods. The objects to be searched correspond to the objects 61 to 63, and some or all of the objects 61 to 63 can be selected as the objects to be searched. The search methods include a search along a line, an inclusive search, a distance search, and a time search, and one of these can be selected.

In S14, when the search conditions are set, the flow shifts to S16, where it is determined whether or not the search range has been designated. Specifying a search range means that a search range corresponding to the selected search method is appropriately specified.

In the case of a search along a line, the search range is specified by specifying the start and end points of the search line and the distance from the search line. That is, as shown in FIG. 5, the search range for the along-line search is first specified on the map 51 by the start point A.
The start point A is set by moving the pointer to a position where the end point B is set, and the end point B is set by moving the pointer to a position where the end point B is set. Then, the distance from the line AB is input.

In the case of an inclusive search, the search range is specified by specifying a search center position and a distance from the center position. That is, as shown in FIG.
After setting the center position C by moving the pointer to a position that becomes the center position C on the center 1, the search range D centering on the center position C is set. in this case,
The shape of the search range D can be arbitrarily selected such as a rectangle, a circle, and a polygon.

In the case of a distance search, the search range is specified by specifying a starting point and a distance. That is, the process is performed by moving the pointer to the start point on the map to set the start point, and then inputting the distance of the road from the start point.

Further, the search range is specified by specifying a start point and a moving time in the case of a time search.
That is, the process is performed by moving the pointer to a position on the map to be the starting point, setting the starting point, and then inputting the travel time by the vehicle or the train from the starting point.

When the search range is specified in S16 of FIG. 3, the process proceeds to S18, and the search process is performed. The search processing is performed by detecting a search target existing within a specified search range.

For example, when the search target along the line is a point-like object such as the location of a person, the search is performed by detecting a search target having a coordinate point in a closed area designated as a search range. In addition, when the search target is a linear object such as a road or a track in the along-the-line search, the search target includes a part included in the closed area designated as the search range, a part included completely in the closed area, and a part included in the closed area. This is done by detecting what crosses the closed area. Furthermore, when the search target is a two-dimensional object such as a facility having a vast site in the search along the line, a part included in the closed area designated as the search range is included completely in the closed area. This is done by detecting objects and those that cross their closed area.

Similarly to the search along the line, the search processing in the inclusive search is performed by detecting the presence, inclusion, and crossing of the coordinate point to be searched in the closed area designated as the search range. Will be

On the other hand, the search processing of the distance search is, for example, as follows.
The search is performed by detecting a search target within a specified distance from the position of the specified start point. For example, if the travel route is a road, the distance from the intersection on the road on the map to the intersection is input in advance to the CD-ROM 8 as distance data, and the distance data is sequentially accumulated in a direction extending from the position of the starting point. A search target that can be accessed using the road portion up to the specified distance is set as a search result. If the travel route is a track, the distance from station to station on the track is input in advance to the CD-ROM 8 as distance data, and the distance data is sequentially accumulated in the direction extending from the position of the starting point, and designated. A search target that can be reached using the track portion up to the distance is set as a search result.

The search processing of the time search is performed by detecting a search target that can be accessed by a vehicle, a train, or the like within a specified time from a position of a specified start point. In the case of a vehicle, the travel time of each vehicle from the intersection on the road to the intersection is input in advance to the CD-ROM 8 as time data, and the time data is sequentially accumulated in the direction extending from the position of the starting point. A search target that can be reached using the road portion up to the destination is defined as a search result. In the case of a track, the travel time of the train from station to station on the track is input in advance to the CD-ROM 8 as time data, and the time data is sequentially accumulated in the direction extending from the starting point position, and the time is accumulated at the designated time. A search target that can be reached using the track portion up to the arrival is defined as a search result.

Then, the flow shifts to S20, where a search result is displayed. In the case of a search along a line, as shown in FIG. 7, the search area is displayed in a different color or pattern from the non-search area, and the search target in the search area is displayed in a different color from that of the non-search area. Also, the search targets in the search area are displayed as a list. From this list, the contents of the search target can be easily grasped.

Also, in the case of the inclusive search, similarly to the search along the line, the search area is displayed in a different color or pattern from the non-search area, and the search target in the search area is different in color from the non-search area. Is displayed. Also, the search targets in the search area are displayed as a list.

On the other hand, as the search results of the distance search and the time search, the roads or tracks included in the search range are displayed in colors different from those in the non-search range.

Then, the flow shifts to S22 in FIG. 3, and it is determined whether or not a print start operation has been performed. If the print start operation has been performed, the flow shifts to S24, where printing processing is performed. The printing process is a process of outputting a map 51 or a list displayed as a search result as a document. For example, in the case of a search along a line, the display screen of the search result shown in FIG. 7 and the contents of the searched object are displayed. The written list is printed out on paper and output. Also, in the case of the inclusion search, similarly to the search along the line, a display screen of the search result and a list describing the contents of the searched object are printed out on a document and output. On the other hand, in the case of a distance search and a time search, a search result display screen is printed out on a document and output. Then, after the printing process ends in S24, the control process ends.

As described above, according to the map search device 1, the map search method, and the recording medium storing the map search control program according to the present embodiment, the search for the linear or two-dimensional shape displayed on the map can be performed. Since it can be performed, it is possible to search for roads and tracks, or to search for a wide facility or the like as a search target.

Further, since the search area can be selected along the line specified on the map, by specifying the track or road on the map, a person living along or along the track or existing along the track or road can be specified. It is possible to easily search for stores and the like.

Also, a so-called designated road search can be performed for searching for a fixed road from a specified position, and a so-called time specified search for searching for a fixed time from a specified position can be performed.

In the present embodiment, a case has been described where the recording medium on which the map search control program is recorded is applied to the CD-ROM 8, but the recording medium according to the present invention is not limited to such. Any other recording medium that can record the map search control program may be used.
