Description

  The present invention relates to a map information display method and a road map using the method.

  In general, a road map is obtained by dividing a wide area map into a plurality of areas in a grid pattern and printing an enlarged map of each area for each page as a partitioned map. On the page frame periphery of each page is an index code such as alphabetic symbols or numbers that further display the division map, the name of the destination reached by following a specific road or railway, and the page corresponding to the adjacent division map Numbers are described.

However, if you follow a specific road and reach the end of the picture frame, there is no indication of which part of the adjacent segment map corresponds to that point. Look at the page that displays the adjacent segment map. However, it was difficult to find the road that had been traced so far quickly and easily. To solve this problem, it has been proposed to print a region that is slightly larger than the segmented map on each page and display the boundary line of the segmented map on the inside to recognize the connection position between the segmented maps. (Patent Document 1).
No. 08-002697

  However, in the method of Patent Document 1, it is still necessary to perform graphic recognition (recognition of shape, color, position, etc.) when following a road. In particular, when the pages are different, it is not easy to find the road on the next page.

  The present invention clearly shows a road connection relationship between single-wafer maps corresponding to adjacent areas and easily and quickly traces the road across a plurality of pages, and a road using this method. The challenge is to provide a map.

  In the map information display method according to the present invention, in a road map that displays a plurality of single-wafer maps corresponding to adjacent regions, each single-wafer map is displayed at the periphery of the frame of each single-wafer map. The road information for identifying the road that has reached the frame is displayed.

  For example, the road information includes a road type and a road number assigned to the road. The road type is preferably represented by a graphic, and the road number is preferably displayed in the graphic.

  The road map according to the present invention is characterized by using the map information display method.

  As described above, according to the present invention, a map information display method that clearly presents a road connection relationship between single-wafer maps corresponding to adjacent regions and can easily and quickly follow a road across a plurality of pages. And a road map using this method can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a partially enlarged view of a wide area map in a road map according to an embodiment of the present invention. As shown in the drawing, the wide area map W is divided into a plurality of rectangular areas (section maps) divided into a grid, and each section map has a page number (23, 24, 27 to 29) on which an enlarged view is displayed. 33-35 etc.). In the present embodiment, one division map is placed on the two spread pages on the left and right of the road map, and the page number is assigned to each spread page.

  FIG. 2 is a partially enlarged view of a single-wafer map on which a section map with page numbers 43 and 50 (not shown in FIG. 1) is added in the wide area map W. That is, the division map 43 (hereinafter, the page number is used as the reference number of the division map) is posted on the 43-page spread sheet map in the road map, and the division map 50 is published on the 50-page spread map. The

  In this embodiment, the division maps 43 and 50 are adjacent in the up-down direction, the division map 43 corresponds to the upper map, and the division map 50 corresponds to the lower map. In the present embodiment, a margin map area having a predetermined width is provided on the four sides around the segmented map. That is, the single-wafer map posted on each spread page publishes a region that is slightly larger than the segmented map with the same page number, and the margin map region is duplicated on two pages.

  FIG. 2 shows a lower side L1 of a single frame map including a section map 43 posted on page 43 and an upper side L2 of a single frame map including a section map 50 posted on page 50. 2, line B corresponds to the lower side of page 43 and the upper side of page 50. Arrow symbols S1, S2, and the like including page numbers of adjacent segment maps are displayed on the periphery of the picture frame of each page. For example, a downward arrow symbol S1 labeled “50” is displayed on the lower side L1 of the picture frame on page 43, and an upward arrow symbol S2 labeled “43” is displayed on the upper side L2 of the figure frame on page 50. Is displayed. As is well known, similar arrow symbols are also provided on the left and right sides (further corners) of the picture frame.

  Further, as is well known in the art, numerals and alphabets for specifying the position of each area when the sheet map is divided into a grid are displayed around each frame. For example, numbers are assigned in the latitude direction and alphabets are assigned in the longitude direction (FIG. 2 shows only the upper and lower sides, so only the alphabet is shown).

  For example, when a road is traced on the division map 50, when the road reaches the upper side L2 of the frame, it can be understood that the map on page 43 may be referred to further follow the road from the arrow symbol S2. However, in the past, only the name of the place that the extension destination of the road reaches reaches, such as “To XX”, on the road that has reached the frame. Therefore, the position at which the edge of the road starts from the lower side L1 of the picture frame on page 43 is determined based on the peripheral figure of the road that has reached the upper side L2 of the picture frame on page 50, It was necessary to find the starting position of the road by comparison (based on the recognition of the shape, color, position, etc.).

  In order to solve such a problem, in the present embodiment, in each single-wafer map, when a main road in the map reaches a picture frame, a symbol (road symbol) S3 for identifying the road in the vicinity thereof, S4, S5, and S6 are added. This symbol includes, for example, information such as a road type (national road, prefectural road, city road, etc.) and a number assigned to each road.

  For example, “National highway No. 19” is generally represented by attaching a national highway number “19” in a blue inverted triangle (figure) with rounded corners representing the national highway. Therefore, in this embodiment, as shown in FIG. 2, the corners are rounded to the position where National Route 19 has reached the upper side L2 of the picture frame on page 50 and the lower side L1 of the picture frame on page 43. Symbols S3 and S4 with the national road number “19” in the inverted triangle are displayed (for example, displayed in the margin area outside the picture frame). The same applies to prefectural roads and city roads. For example, graphics (including color differences), letters, and combination symbols commonly used to represent prefectural roads, city roads, etc. Is displayed at the position (outside of the picture frame) that has reached the picture frame.

  Thus, when the road is reached on one page and reaches one side of the picture frame, the symbol and number written at that position are stored, and the stored symbol and number are found on one side of the corresponding picture frame on the next page. With this, it is possible to find the start position of the road on the next page.

  As described above, according to the present embodiment, even when a road is traced across a plurality of pages without performing graphic recognition, the road can be found on each page very easily. As a result, the road can be traced across a plurality of pages extremely easily, quickly and reliably.

  Further, in the above embodiment, the case where the wide area map is divided into grids of the same size has been described as an example, but the map information display method of the present embodiment is, for example, in the case where the scale is different. It is particularly effective. For example, the division map 23 and the division map 28 shown in FIG. 1 are adjacent to each other, but their scales are different. In such a case, for example, when the user moves to the division map 23 by following the road at the upper left end of the division map 28, it is intuitively considered to be connected to the lower left end. It exists in the lower center part of the map 23. In such a case, it is possible to quickly find the road by displaying the corresponding road symbol around the frame of the division map 23.

  Further, for example, the area around “Ichinomiya City” shown in FIG. 1 has a larger amount of information to be displayed than the surrounding area, and therefore, for example, the area indicated by the frame F is displayed on one page of the spread. At this time, the scale is greatly different from the division map 24. Even in such a case, for example, a frame corresponding to the picture frame F is displayed in the division map 24, a road symbol is displayed around the frame, and an enlarged figure in the picture frame F is displayed. By displaying the corresponding road symbol in the peripheral portion, the same effect can be obtained between maps with different scales.

  In the present embodiment, the margin map area is provided around the segmented map, but it goes without saying that the map information display method of the present embodiment can be applied even when the margin map area is not provided.

  In the present embodiment, a map printed on paper has been described as an example, but the present invention is not limited to this. For example, in an application that displays on the display the exact same map surface as the map printed on paper, click the arrow symbol that indicates the adjacent segment page placed around the picture frame of the displayed segment map to display that page. Needless to say, the map information display method of the present embodiment can be applied.

  Therefore, in the claims and the specification of the present application, the term “sheet map” is not limited to a map printed on paper, but includes a map displayed in a sheet form on a display as described above.

It is the elements on larger scale of the wide area figure in the road map which is one Embodiment of this invention. It is the elements on larger scale of the sheet map on which the division | segmentation map to which the page numbers 43 and 50 were attached | subjected in the wide area figure was published.
