The present invention relates to the field of the Internet, and in particular, to a method and apparatus for displaying an associated label point on an electronic map interface. Background technique

Currently, electronic maps have been able to provide users with POI (Point of Interest) search capabilities. When the user performs a P0I search through the electronic map, the electronic map client displays each P0I obtained by the search in the form of a marked point on the corresponding position of the electronic map interface. In the electronic map, a P0I can be a bank, a shop, a school, a bus station, and so on.

After displaying the label points on the map interface, the user can find the specific location of the P0I to be found in the displayed label points. And when the user moves the cursor to a marked point, the marked point will be illuminated, so that the user can know the currently selected P0I.

For example, when a keyword searched by a user in an electronic map is "bank", the client will mark all P0Is (such as ICBC, Construction Bank, Minsheng Bank, etc.) about "Bank" in the search area on the map interface. The form of the point is presented to the user. Among them, the meaning of each point of annotation is independent, that is, each label point represents a banking outlet. When the user moves the cursor to a marked point, the marked point is illuminated and displays the identified bank name (such as the branch of Zhichun Road of Industrial and Commercial Bank of China). For details, please refer to the electronic map interface shown in Figure 1. A schematic diagram of the label points. As can be seen from Figure 1, if the user wants to view a bank with the same type of bank facilities (such as ICBC), it is necessary to click the label point one by one to know the bank identified by each label point.

In summary, in the prior art, when a user wants to search for a P0I of the same type of facility on the electronic map interface, it is necessary to click each of the labeled points one by one to find the P0I of the same facility type, thereby causing the user to The search efficiency is low, and the user experience is better.

By the method, when the user selects any label point on the map interface, the client can acquire the facility type of the POI data identified by the label point, and search through the database for the POI data of the same facility type as the POI data, and further Highlight the label points that identify these POI data. It can be seen that, by the method provided in this embodiment, the user can quickly and accurately locate the target POI through the marked points highlighted on the electronic map, which facilitates the user to perform POI search, improves the search efficiency, and improves the user experience.

Embodiment 2

This embodiment is a specific application scenario of the foregoing first embodiment. Through the embodiment, the method provided by the present invention can be more clearly and specifically illustrated.

FIG. 3 is a flow chart showing a method for displaying an associated label point on an electronic map interface according to an embodiment of the invention. The method specifically includes steps S301 to 306.

S301. The client obtains the label point currently selected by the user on the electronic map.

In this embodiment, on the electronic map displaying a plurality of marked points, the user can move the cursor to the label point to be selected. At this time, the label point is the label point currently selected by the user acquired by the client.

After obtaining the label point selected by the user, the client performs step S302 to obtain the label. Note the type of facility to which the identified POI data belongs.

It should be noted that, in this embodiment, the POI marked in the electronic map is a specific geographic location, and is represented by POI data (that is, the name of the geographic location pointed by the POI), for example, "Bank of Beijing" Zhichun Road Branch", "Beijing Medical University Third Hospital" and so on.

Optionally, step S302 can be specifically implemented as follows:

First, the client obtains the POI information of the POI data identified by the label point.

It should be noted that, before the step S301, the client has obtained the POI information of each POI data corresponding to the displayed label point when performing the label point display. The POI information in this embodiment includes at least location information and a facility type code. For example, for the POI of the Bank of Beijing Zhichun Road Sub-branch, its POI information includes the latitude and longitude of the Bank of Beijing Zhichun Road Sub-branch and the type code of the Beijing Bank.

Second, the client looks up the facility type code in the POI information to determine the type of facility to which the POI data belongs.

In this embodiment, a specific field, that is, a type identifier typeld field, is stored in the POI information for storing a facility type code, wherein the facility type code is used to indicate a facility type to which the POI data belongs. For ease of management and differentiation, a specific facility type code is set for each different facility type. And the specific facility type code is written into the typeld field of its POI information according to the type of facility to which the POI data belongs. For example, when the facility type to which the POI data belongs is "ICBC", the facility type code can be set to "bOOOOOl". When the facility type of the POI data belongs to "KFC", the facility type code can be set to "fOOOOOL". .

After obtaining the facility type to which the POI data selected by the user belongs, the client performs step S303, that is, sends a region search request to the database to obtain the same facility type corresponding to the user selected label point in the adjustable region. Each POI data.

In this embodiment, the database is located in the peer server of the client. The area search request includes at least the facility type code corresponding to the label point selected by the user and the location information of the label point. Optionally, the location information includes at least a current city name displayed by the electronic map and a location coordinate of the marked point.

After receiving the area search request, the database performs step S304, that is, the database searches for the same POI data as the received facility type code in the adjustable area according to the area search request, and forms the POI data obtained by the search into a POI association set.

In this embodiment, after receiving the area search request, the database may be obtained as follows:

POI association set: First, the area search request is read and the location coordinates and facility type code of the POI data included therein are acquired.

Next, the content of the typeld field in the POI information of each POI data is read in a circular area with the adjustable distance as the center centered on the position coordinates of the label point, and the facility type code is obtained.

In this embodiment, the POI information of each POI data is stored in the database, as shown in Table 1.

POI data 1

Location information 1 facility type code 1

POI data 2

Location information 2 facility type code 2

POI data 3

Location Information 3 Facility Type Code 3

It should be noted that, in this embodiment, in order to adapt to the displayable range of the client display screen, optionally, the adjustable distance may be selected as 2 km, and the search pressure of the database is also moderately reduced.

Again, the facility type code in each POI information is compared with the received facility type code, and the POI data represented by all the comparatively successful facility type codes in the adjustable area is obtained and composed into a POI association set. The POI association set includes POI information of each POI data.

After obtaining the POI association set, the database performs step S305, and sends the POI association set to the client.

After the client receives the POI association set, step S306 is performed, that is, on the electronic map interface, the label points corresponding to the respective POI data in the POI association set are highlighted.

In this embodiment, the client separately reads the location information of each POI data in the POI association set, and highlights the label points on the corresponding positions in the electronic map.

It should be noted that, in order to facilitate the user to distinguish the highlighted label points from the unhighlighted label points, the client can highlight the label points in at least one of the following ways: zoom in, change color, change shape, change dynamics effect. In this embodiment, an amplification method is taken as an example. The label points are highlighted, and the specific effects are shown in Figure 4.

In order to more clearly show the highlighted label points, this embodiment also provides a schematic view of the label points before they are highlighted, that is, Fig. 5. As can be seen from the comparison between Figure 4 and Figure 5, the highlighted label points enable users to view POI data of the same facility type in a region more quickly and accurately.
