Description

How to display the map when zooming the map

The present invention relates to a method for displaying a dynamic low level period by using a degree of utilization when a map is zoomed in and out, and a period of a lower level is dynamically expressed in advance to a higher level according to the purpose of utilizing information when a vector map is zoomed in or out. Therefore, the present invention relates to a dynamic low-level period display method using utilization in map zooming / reducing to meet user's needs.

In general, when zooming in or out according to the zoom level of a vector map, a logical expression period for a period or a name is already defined for each map of each level according to the zoom level, and according to the specification of the display period of the zoom period. It is expressed statically.

For example, FIG. 1 is an exemplary view of a leaf showing a general top level, FIG. 2 is an illustration of a leaf showing a general upper level, and FIG. 3 is an illustration of a leaf showing a general lower level, In the display of the map according to the zoom level of the vector map, the map of FIG. 1 is relatively large scale and is only displayed at the highest period.

In addition, since the leaf of FIG. 2 is enlarged about the B department store of FIG. 1, the period according to the leaf of FIG.

In addition, the leaf of FIG. 3 is a leaf that is further enlarged around the department store B of FIG. 2, and thus detailed cycles that are shown in detail can be expressed.

However, each of the maps has periods fixed in advance in the period table according to each map level, and these periods are simply displayed statically on the screen. Inconvenience to check the position in the lower level of the leaf as shown in FIG.

As a conventional technique for improving the above-mentioned problem, a variable scale display method of an electronic map for vehicle navigation is known in Korean Patent Laid-Open No. 2001-0009297.

The prior art relates to a variable scale display method of an electronic map for vehicle navigation in which a scale of an electronic map can be variably displayed using a variable scale in addition to the conventional scale method.

There is a need for a dynamic low-level period display method for displaying and confirming a period of a lower level using a degree of utilization in advance at a higher level when expanding / reducing a leaf.

According to an aspect of the present invention, an object of the present invention is to display in advance the period of the lower level using the utilization in the upper level in the enlargement / reduction of the leaf according to the zoom level of several stages.

According to another aspect of the present invention, in the dynamic low-level period display method, the width of an object located at the center of the screen occupies 30% or more of the screen area, or the map movement occurs within a certain radius. There is another purpose of dynamically expressing a lower level period by applying a zooming operation of a landmark object or when zooming of an object having a large number of searches or occupancy occurs by statistics.

According to one aspect of the invention, the present invention comprises the steps of: setting at least one first level logic period among the displayed periods in the map of the first level; Setting at least one second level logic period among the expressed periods in the map of the second level lower than the first level; Applying the at least one second level logic period to the period table of the first level; And expressing the at least one second-level logic period in the first-level map based on the period table of the first level, wherein the detailed POI information of the second level is displayed in the first level. It provides a map display method when the map zoom in / zoom out, characterized in that selectively expressed in the level.

At least one of the at least one first level logic period and the at least one second level logic period is optional for expressing a period of a specific point or facility of the first level or the second level upon map zoom in / out. Can be set.

At least one of the at least one first level logic period and the at least one second level logic period may be stored and managed in a database of a map providing server according to a user's setting.

In the step of applying the at least one second level logic period to the period table of the first level, the at least one second when the point corresponding to the center coordinates of the first level is a landmark object or a main point A level logic period may be applied to the period table of the first level.

The step of expressing the at least one second-level logic period on the map of the first level may be performed when only an enlargement / reduction operation occurs without centering the map.

The step of expressing the at least one second-level logic period in the first level map is performed when the width of the object located at the center of the screen occupies more than a preset ratio of the screen area and the zooming operation of the object occurs. Can be done.

The preset ratio may be 30%.

The step of expressing the at least one second level logic period in the map of the first level may be performed when an enlargement / reduction operation of a landmark object occurs when the map movement of the first level occurs within a predetermined radius.

Expressing the at least one second-level logic period to the first level map, wherein the number of searches or occupancy obtained by the statistical value is greater than or equal to a predetermined reference value among the objects of the at least one second-level logic period; The above objects can be expressed.

Applying the number of searches or occupancy based on the statistics is based on the cloud database or big data information retrieval and statistically doubled the number of searches more than the surrounding objects or the percentage of the top 1 to 3 statistically compared to the surrounding objects. It may be any one of.

According to one aspect of the present invention, when the map is enlarged / reduced, not by static data display defined in the map data, by dynamically determining in advance the purpose of the user to use the information by zooming in / out by expressing the dynamic display in advance. It is effective to meet the needs of users.

In addition, according to another aspect of the present invention, the present invention is to display the period of the user-selected or statistically analyzed map leaf at the upper zoom level, detailed POI information that can not be expressed at the current level when the vector map zoom in / zoom out Extract and display at a lower level in advance to save time and prevent waste of data.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is a flowchart illustrating a method for displaying a dynamic low level period using utilization when a map is enlarged / reduced according to an embodiment of the present invention.

As shown in the present invention, in the method of displaying a screen period when the user's vector map is enlarged / reduced, the first step (S100) of setting a high level logic period in the displayed period in the map from the upper level map (S100), the lower level map In the second step (S200) of setting a low-level logic period in the expressed period in the leaf at step S3, a third step (S300) and the first step of applying the logic period set in the lower level to the period table of the higher level ( S100 and the logic level period of the second step (S200) are combined, and comprises a fourth step (S400) of selectively displaying the logic period of the lower level in the upper layer of the upper layer, thereby The period of detailed POI information of the lower level that cannot be expressed in the level can be selectively extracted in advance from the lower level and displayed on the upper level screen.

The upper level map is a large area to include an object such as the specific point, building or facility in a step in which the user confirms the location of an object such as a specific point or building or facility or reduces the map to search for a map. It is a green leaf in which scale is formed.

In addition, the leaf of the lower level refers to a leaf in a detailed enlarged state formed at a scale that expresses a specific area of an object such as a specific point or a building or a facility into a narrower area than the leaf of the upper level.

Therefore, the leaf of the lower level means that the leaf contains a detailed logic period when the leaf of the upper level is further enlarged.

FIG. 2 is an exemplary view of a map showing a general upper level, and the upper level logic period means a period of a drawing expressed in the upper level map, for example, in the map of FIG. 2, the A hotel, the B department store, and the C Periods such as Cultural Center, D Building, and E Building are the upper level logical periods.

Label in the Map Data is a string that is input to explain the ideas that appear on the map.

Therefore, the lower level logic period is a period of the drawing expressed in the lower level map, for example, FIG. 3 is an exemplary view of a map showing a general lower level, and as shown in FIG. 3, the shelter, the entrance, the back door, and the general Parking cycles, women-only parking lots, restaurants, coffee shops, and the like in the lower level maps are the lower level logical cycles.

The first step (S100) of setting the upper level logic period means that a user selectively selects a specific point, building or facility among the cycles of the upper level map and stores it in the user logic period table. For example, a user may select a hotel A as a logic period 1, a department store B as a logic period 2, and a C culture center as a logic period 3 among the periods of the upper level maps, and store them in the upper level logical period table.

5 is an exemplary diagram illustrating extracting a logic level of a lower level according to an embodiment of the present invention, and the second step (S200) of setting the lower level logic period is performed by the user. This is to select a specific place and save it in the user logical cycle table. For example, the entrance, the back door, and the women-only parking lot are configured as logic cycle 1, the information, coffee shop, and general parking lot are logical cycle 2, and the shelter, restaurant, and general parking lot are logical cycle 3, among the cycles of the lower level leaf. Can be selected and stored in the lower-level logical period table.

The logic period of the upper level or lower level is stored and managed in a database of a map providing server according to the user's setting.

Therefore, the logical period is set and stored by the user selectively to display the period of the specific point or facility of the upper level or the lower level even when the map is enlarged or reduced.

The third step (S300) is a step of periodically combining the logical period set in the lower level with the period table of the upper level and storing the logical period in the table. For example, the logic periods 1, 2, and 3 set at the lower level are periodically combined with the department store B, which is the logic period 2 of the upper level, and the user selects any one of the logic periods 1, 2, and 3 set at the lower level. Select to display at the upper level.

Also, the third step S300 may be performed when the point corresponding to the center coordinate of the upper level is an object including landmark background / name or detailed information, a main point, or based on cloud / big data. In the case of a point / facility with a large number of searches, the logical period set in the lower level may be applied to the period table of the upper level.

FIG. 6 is an exemplary view of a map showing a logical period of a lower level selectively expressed in a higher level according to an embodiment of the present invention, and cannot be represented at the higher level according to the flow of the above-described embodiment of the present invention. By selectively extracting and specifying the detailed POI information of the lower level in advance from the lower level, the POI information can be dynamically displayed on the upper level screen.

In addition, the fourth step S400 is a step in which the set logic period of the lower level is expressed in the upper level map. In the case where a combination of periods is generated and expressed in the upper level, there may be the following cases.

First, when a detailed logic period is included in the object of the lower level, the logic period of the lower level set when the zooming operation is performed without generating the center movement of the map does not occur. If it is.

Secondly, the lower level object includes a detailed logic period, and the lower level set when the width of the object located at the center of the screen occupies 30% or more of the screen area and the zooming operation of the object occurs. This is the case where the logical period of is expressed in the upper layer.

Third, the lower level object is set when a combination of periods occurs at the upper level when a zooming operation of a landmark object including a detailed logic period is included in the lower level object and a map movement occurs within a predetermined radius. This is the case where the logic period of the level is expressed in the upper layer.

Fourth, the logic level of the lower level, which is set when the object of the lower level includes a detailed logic period and an enlargement / reduction operation of an object having a large number of retrieval occurs by statistics, is displayed on the upper level map. If it is.

7 is an exemplary view showing the number of searches and the occupancy of the upper level objects according to an embodiment of the present invention, the objects having a high number of searches are statistically compared to the surrounding objects based on a cloud database or big data information search This is the case of having more than 2 times the number of search times or the percentage (%) occupancy of the top 1-3 in relation to the surrounding objects.

FIG. 8 is an exemplary view showing a search frequency and occupancy rate of a lower level object according to an exemplary embodiment of the present invention. An object having a percent (%) occupancy of ˜3 can be dynamically displayed at the upper level.

9 is an exemplary view of a map showing a general upper level according to an embodiment of the present invention, FIG. 10 is an illustration of a map showing a general lower level, and FIG. 11 is a lower view according to an embodiment of the present invention. It is an exemplary view of a drawing showing that the logic period of a level is selectively expressed at a higher level.

As shown in FIG. 9, the lower level of FIG. 10, which is not displayed in the upper level of FIG. 9, is selectively extracted in advance as shown in FIG. 11 and dynamically displayed on the screen of the upper level.

The present invention can be equally applied to navigation maps of navigation and vector maps on a web based on a browser.

Although the present invention has been shown and described with reference to preferred embodiments as described above, it is not limited to the above embodiments and should be made by those skilled in the art to which the present invention pertains without departing from the spirit of the present invention.
