The layers are superimposed. For example, on the existing electronic map, the "division" layer, the "block" layer, the "water system" layer, the "green area" layer, the "road" layer, "P0I" are respectively designed. "Layer, then layer the latter image onto the previous layer, and set the multiple layers accordingly. The above "P0I" is, "Point of Interest" means the point of interest. On the electronic map, the "P0I" layer is set at the top of all layers, and there are multiple P0Is on the "P0I" layer, each P0I Points can contain a variety of information, such as name, category, longitude, latitude and so on. Strictly speaking, all P0I points on the electronic map need to be collected in the field to ensure the accuracy of the information.

Ajax: Ajax technology is now a common technical implementation of electronic maps. Ajax is not a technology, but a combination of technologies, including XHTML and CSS for controlling web page styles, DocumentObjectModel for dynamic display and interaction, XML Data interaction and operation with XSLT, asynchronous data reception with XMLHttpRequest, and JavaScript binding. The browser provides users with a more natural browsing experience through Ajax technology.

The specific technical solutions of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

The problem addressed by the present invention is that a particular symbol is displayed on an electronic map, in particular selectively displayed from a large number of specific symbols in accordance with a prioritized order.

FIG. 1 is a schematic diagram showing the overall structure of a system for displaying a specific symbol in priority order in an electronic map according to the present invention.

A system 100 for displaying specific symbols in a prioritized order in an electronic map includes a server 1 and at least one client 2.

The client 2 can be a mobile communication device such as a mobile phone or a PDA, or a data processing device such as a computer. The server 1 and the client 2 are connected by a network device. Various specific implementations for achieving network connectivity are within the scope of the present disclosure. The client 2 can be installed with an internet application, accessing the server via the Internet, and having a browser for downloading an electronic map from the server.

The server 1 is for providing an electronic map service to the client 2. After establishing a connection with the server 1, the client 2 can issue a request for displaying an electronic map to the server 1, and the server 1 obtains an electronic map of the corresponding range according to the request, and transmits it to the client 2. At the same time, the server 1 can provide users with more extensive travel, business, cultural and other service information by adding specific symbols based on geographic information in the electronic map. The specific symbol can be, for example, a landmark advertisement, and mark it at a corresponding position on the map, so that when viewing the map, the user can clearly understand the specific geographical location and its related service type, and at the same time achieve the eye-catching advertisement effect. '

Taking an example of a landmark advertisement as an example, in actual operation, for the sake of industry consideration, the service provider of the maintenance server 1 usually requires a specific user to provide the price, and then the electricity is issued to all the clients 1. The special symbol (landmark advertisement) required by a specific user is specifically embedded in the submap. Due to the hardware limitations of the client 2 displaying the electronic map, and for maintaining the user experience, a large number of landmark advertisements cannot be implanted in an currently displayed electronic map. The technical solution provided by the present invention can determine the priority order of displaying landmark advertisements according to the level of bidding of a specific user.

As shown in FIG. 2, it is a schematic structural diagram of the server 1. In the prior art, the module that the server 1 usually possesses is not described in detail in the present invention, and only related modules related to the present technical solution are described.

The server 1 includes a processing device 11, a data storage device 12, a map database 13, and a communication device.

14.

The map database 13 stores geographic information data, that is, an electronic map.

The data storage device 12 serves as a database in which a parameter comparison table is stored, and the parameter comparison table includes a plurality of fields, such as a position information field, a numerical parameter field, and a specific symbol field. The location information field is, for example, a coordinate point field for recording a coordinate point of the electronic map in the map database 13, for example, a latitude and longitude value. Position information, numerical parameters, and specific symbols correspond to each other. SP, in a data of the parameter comparison table, includes a coordinate value of a coordinate point, a price of the specific user for the coordinate point, and a specific symbol preset by the specific user for the coordinate point, that is, a landmark advertisement. Subsequently, the server will perform an auction rule based on the numeric parameter to determine the priority order for displaying the respective landmark advertisements for different specific users.

The processing device 11 is used for data processing work.

The communication device 14 is for connecting to the client 2 to transmit and receive data.

In the present invention, an electronic map of a predetermined scale is used as a reference layer, and different scales correspond to different layers. The electronic map of the reference layer is equally divided into a plurality of regional units, and each regional unit may be, for example, a single grid, and other manners of dividing the regional units are also within the scope of the present application. Then, according to the parameter comparison table stored in the data storage device 12, the processing device 11 can calculate, according to the area unit divided for the reference layer, all the coordinate points covered by each area unit, and the coordinate values thereof are recorded in the parameter. Compare the coordinate points in the table, and find the highest value among the corresponding numerical parameters from these coordinate points, and use the highest numerical parameter covered by each regional unit as the representative numerical parameter of the regional unit, ie, Each regional unit has a representative numerical parameter. In other applications, the minimum value of the numerical parameters can also be used as a representative numerical parameter as needed. For example, when the numerical parameter represents a level, the lower the number of levels, the higher the priority, such as level 1 higher than level 2, etc., then the minimum value in the numerical parameter is selected as the representative numerical parameter of the unit of the area. Subsequent selection in the auction rules A specific number of specific symbols with the lowest numerical parameters are displayed.

At different scales, that is, between different layers, the regional units have a mapping relationship, that is, electronic maps of different scales, when corresponding to the same display area, the range of latitude and longitude that can be displayed is different, and there is an inclusion relationship between them. The data storage device 12 can also store information on the area unit in which each coordinate point is at a different layer (different scale). Thus, the processing device 11 can calculate a representative value parameter for each of the area units in each layer based on the data stored in the data storage device 12.

For example, as shown in FIG. 3, a schematic diagram of a regional unit mapping relationship. The four area units of the lower layer correspond to one area unit of the upper layer. Then, the highest representative numerical parameter among the four regional units below one regional unit of the upper layer is the representative numerical parameter of the upper regional unit. The number of area units participating in the lower layer of the map is not limited to this. According to this rule, in all the layers, the representative numerical parameter of each regional unit can be determined, and the corresponding specific symbol is used as the symbol of the priority of the region unit of the layer.

In an optimized embodiment, the electronic map of the largest scale that the system 100 can support is divided into a plurality of reference area units, and at least one of the reference area units is correspondingly provided with a specific symbol. That is, all the specific symbols are preset in the lowest level electronic map. The data storage device 12 is configured as a database, wherein a parameter comparison table is stored, the parameter comparison table includes a plurality of fields, including an identifier code field for identifying a reference area unit (different identification codes corresponding to different area ranges, and thus substantially Corresponding to a location information), a specific symbol corresponding to the reference area unit (for example, a landmark advertisement), and a representative numerical parameter corresponding to the specific symbol, for example, an advertiser's bid for the specific symbol. That is, in the present embodiment, the representative numerical parameter of each reference area unit is not obtained by calculation, but is obtained by a preset manner.

Similar to the previous embodiment, the regional units have mapping relationships at different scales, that is, between different layers. For example, as shown in FIG. 3, a schematic diagram of a regional unit mapping relationship. The four area units of the lower layer correspond to one area unit of the upper layer. Then, the highest representative numerical parameter among the four regional units below one regional unit of the upper layer is the representative numerical parameter of the upper regional unit. The number of regional units participating in the lower layer of the mapping is not limited to this. The data storage device 12 can store corresponding information between different layers (different scales) and area units. According to such a rule, the processing device 11 can determine the representative numerical parameter of each regional unit in all the layers (the specific symbol and the representative numerical parameter corresponding to the reference region unit are preset), and the corresponding specific symbol is used as the The area of the layer is preferred The symbol shown. At the same time, an electronic map of a suitable scale can be preset as a reference layer, for example, a normal scale for user convenience.

4 is a flow chart of a method for performing a bidding rule to display a particular symbol in a prioritized order in an electronic map, as shown in FIG.

Step 401: The client 2 sends a request for displaying an electronic map to the server 1;

Step 402: The communication device 14 receives the display electronic map request, and the processing device 11 acquires the display range corresponding to the display electronic map request and the display layer;

When the communication device 14 first receives the request to display the electronic map, the display range is usually the default range in the reference layer, or a preset layer and a preset range;

Step 403, the processing device 11 acquires, according to the parameter comparison table stored in the data storage device 12, a representative numerical parameter of each regional unit in the display layer in the display range;

That is, the processing device 11 calculates the coordinate points located in the display range, and respectively takes the highest value from the representative numerical parameters of the lower regional unit of each regional unit in the display layer to obtain each of the currently displayed layers. The representative numeric parameter of the regional unit;

Alternatively, corresponding to the above optimized embodiment, the processing device 11 calculates a regional unit located in the display range, and takes the highest value from the representative numerical parameters of the lower regional unit of each regional unit to obtain the current display layer. Representative numerical parameters of each regional unit;

Step 404, the processing device 11 acquires a previous specific number of the representative numerical parameters having the largest value among the respective regional units in the display range, and acquires a specific number of the specific symbols corresponding to the representative numerical parameter according to the parameter comparison table. ;

Since the specific symbols displayed cannot overlap each other, a plurality of specific symbols located in different regional units are selected in the step, and the higher the representative numerical parameter is preferred; the specific number of specific values are set with the client 2 The display condition is related to, or is the default value, or related to the size of the map being opened.

Step 405, the processing device 11 takes out the electronic map of the display layer and the display range from the map database 13;

Steps 403 and 405 are interchangeable;

Step 406, the processing device 11 inserts the specific symbols into the extracted electronic map according to the location information thereof;

That is, the processing device 11 inserts the extracted electronic ground according to the coordinate points corresponding to the specific symbols. In the figure;

Alternatively, corresponding to the above-described optimized embodiment, the processing device 11 inserts the specific symbols into the corresponding area units in the electronic map of the extracted current layer based on the data recorded in the data storage device 12;

Step 407, the communication device 14 sends the electronic map to the client 2 for display.

In the above manner, the higher the bid price of the landmark advertisement is, the more likely it is to be displayed on the electronic map. The invention can realize program communication between the client and the server through AJAX technology.

Since the user uses the client to browse the electronic map, the electronic map is also scaled, g[3, zoom-out and zoom-in operation. Figure 5 shows a flow chart of the method of displaying specific symbols in a prioritized order on an electronic map when performing a zoom out operation.

Step 501: The client 2 sends a display electronic map request to the server 1, where the request for reducing the map is performed, and the display layer in the request is a reduced layer;

The request to zoom out of the map is usually performed when the client 2 issues a request to display the electronic map twice, that is, after the client 2 receives the default electronic map for the first time, it is necessary to perform the zoom-out operation; Step 502, the communication device 14 Receiving the display electronic map request, the processing device 11 acquires the display range corresponding to the display electronic map request and the reduced layer;

Step 503, the processing device 11 calculates a representative numerical parameter of each regional unit in the reduced layer according to the data in the data storage device 12;

The processing device 11 extracts data corresponding to the reduced layer in the data storage device 12, that is, each specific number of regional units adjacent to the current layer is corresponding to one regional unit of the reduced layer, Deriving a maximum value of a specific number of representative numerical parameters of a specific number of regional units as a representative numerical parameter of the regional unit in the reduced layer;

If the request is for the client 2 to issue a display electronic map request twice, the processing device 11 determines a plurality of regional units in the reference layer corresponding to one upper layer unit, and determines a representative numerical parameter (ie, multiple corresponding to the plurality of regional units) Represents the maximum value in the numerical parameter as the representative numerical parameter of the upper layer region unit);

If the request is a request for the client 2 to re-send the map based on the enlarged electronic map, the processing device 11 performs the step 503 according to the layer on which the enlarged electronic map is located; If the request is a request for the client 2 to re-send the map based on the reduced electronic map, the processing device 11 performs the step 503 according to the layer on which the reduced electronic map is located;

The processing device 11 can specifically implement the step by using a quad-tree method. In addition, the processing device 11 can cyclically execute step 503 to obtain parameters of the area unit of the scale corresponding to the reduced layer;

Step 504, the processing device 11 acquires a previous specific number of the representative numerical parameters having the largest value among the respective regional units in the display range, and acquires a specific number of the specific symbols according to the parameter comparison table;

Step 505, the processing device 11 takes out the display layer corresponding to the request for zooming out the map and the electronic map of the display range from the map database 13;

Step 506, the processing device 11 inserts the specific symbols into the extracted electronic map according to their corresponding location information;

That is, the processing device 11 inserts these specific symbols into the extracted electronic map according to their corresponding coordinate points;

Alternatively, corresponding to the above-described optimized embodiment, the processing device 11 inserts the specific symbols into corresponding positions in the extracted electronic map according to their corresponding area units;

Step 507, the communication device 14 sends the electronic map to the client 2 for display.

Even if the scale changes, the electronic map is reduced, and it is displayed with a specific symbol representing a high numerical parameter in a specific area.

Figure 6 shows a flow chart of the method of displaying a specific symbol in order of priority in an electronic map when performing an enlargement operation.

Step 601, the client 2 sends a display electronic map request to the server 1, which includes a request for enlarging the map, and the display layer in the request is an enlarged layer;

The request to enlarge the map is usually performed at or after the second time the client 2 requests to display the electronic map, that is, after the client 2 receives the default electronic map for the first time, it is necessary to perform the enlargement operation; Step 602, the communication device 14 Receiving the display electronic map request, the processing device 11 acquires the display range corresponding to the display electronic map request and the enlarged layer;

Step 603, the processing device 11 calculates a representative numerical parameter of each regional unit in the enlarged layer according to the data stored in the data storage device 12; The processing device 11 extracts data corresponding to the enlarged layer in the data storage device 12, that is, divides each region unit in the current layer into equal divisions, and at least one cycle aliquots the cutting step to achieve the amplification. The scale corresponding to the layer, gp, the same screen display area, showing the unit of the lower layer after cutting, and its display scale is enlarged;

For example, for four equal parts, the number of equal parts is not limited to this;

If the request is a request for the client 2 to re-send the map based on the enlarged electronic map, the processing device 11 takes the layer on which the enlarged electronic map is located as the current layer, and performs a cyclic halving cutting step;

If the request is a request for the client 2 to re-send the map based on the reduced electronic map, the processing device 11 takes the layer on which the reduced electronic map is located as the current layer, and performs a cyclic halving cutting step;

Step 604, the processing device 11 obtains, according to the data stored in the data storage device 12, the first specific number of the representative numerical parameters having the largest value among the respective regional units in the display range in the enlarged layer, and according to The parameter comparison table obtains a specific number of the specific symbols;

If there is no numerical parameter corresponding to each area unit after cutting, it is not displayed; Step 605, the processing device 11 takes out the display layer corresponding to the request for enlarging the map from the map database 13 and the display range Electronic map;

Step 606, the processing device 11 inserts the specific symbols into the extracted electronic map according to their corresponding location information;

Corresponding to the above optimized embodiment, the processing device 11 inserts the specific symbols into corresponding positions in the extracted electronic map according to their corresponding area units;

Step 607, the communication device 14 sends the electronic map to the client 2 for display.

In addition, since the main purpose of the electronic map is to provide map information to the user, it is not necessary to overcrowd and destroy the user experience, so that no other landmark advertisements are displayed within a certain distance around each landmark advertisement. The way to avoid overcrowding of landmark ads is to prevent ads from two adjacent squares from appearing at the same time.

See Figure 7 for a flow chart to avoid overcrowding. The step 404 further includes: Step 701: The server acquires a maximum representative value parameter of each area unit of the display range of the display layer; Step 702, excluding a regional unit corresponding to a largest representative numerical parameter in the display layer and an adjacent regional unit thereof;

There are 8 regional units adjacent to it;

Step 703: Acquire a current maximum representative value parameter in the remaining area unit in the display layer, and perform step 702 cyclically until the specific number of representative numerical parameters are obtained.

The specific quantity is related to the display condition of the client 2, for example, 5, not limited thereto; Step 704, the server acquires the corresponding specific quantity from the data storage device according to the obtained specific number of representative numerical parameters. Specific symbols.

The above steps are such that any two specific symbols that are finally displayed are not adjacent, and the display opportunity is obtained with a high bid (value parameter).

The user can also send a request for moving the electronic map through the client 2, and the mobile electronic map does not change the display layer, and only changes the display range. A flow chart of a method for moving an electronic map is shown in FIG.

Step 801, the client 2 sends a mobile electronic map request to the server 1, where the request includes a range of purposes to be displayed;

Step 802, the communication device 14 receives the mobile electronic map request, and the processing device 11 acquires the destination range corresponding to the mobile electronic map request;

Step 803, the processing device 11 scans and acquires the number of the specific number of the specific symbols currently displayed on the client 2, and the location information thereof does not belong to the destination range;

艮卩, its coordinate point does not belong to the scope of purpose, or its regional unit is no longer within the scope of purpose;

Step 804, the processing device 11 determines whether the number is greater than zero, if greater than zero, step 806 is performed, if equal to zero, step 805 is performed;

Step 805, the processing device 11 extracts the electronic map of the destination range from the map database 13, and inserts a specific number of specific symbols that have been displayed, according to the corresponding location information, into the extracted electronic map, and sends the information to the client 2 Display

Step 806, the processing device 11 obtains, among the various regional units in the target range, the number of the representative numerical parameters with the largest value except the representative numerical parameter of the specific symbol that has been displayed, and obtains the corresponding parameter according to the parameter comparison table. Specific symbol

That is to say, the operation of moving the electronic map causes several specific symbols to be removed, and then reselects the remaining regional units, representing several specific symbols with the highest numerical parameters; Step 807, the processing device 11 extracts the electronic map of the destination range from the map database 13; Step 808, the processing device 11 displays the specific symbol that has been retained in the destination range and the specific symbol acquired in the step 806, according to the Corresponding location information is inserted into the extracted electronic map;

Step 809, the communication device 14 sends the electronic map to the client 2 for display.

The above steps make it unnecessary to change the specific symbols that have been displayed in the process of moving, which ensures the continuity of the display, avoids the occurrence of the specific symbol flickering when the electronic map is moved as much as possible, and improves the user experience. In another embodiment, the mobile electronic map may completely reselect a number of specific symbols with the highest numerical parameters in the target range for display.

Specific users can bid on the web or adjust their bids.

The specific user sends a reference value parameter for a coordinate point or a basic area unit and a corresponding specific symbol to the server through the authorized client;

Determining, by the server, whether the reference numerical parameter is larger than a regional unit to which the coordinate point belongs in the reference layer or a current representative numerical parameter of the basic regional unit, and if yes, using the reference numerical parameter as a representative numerical parameter of the regional unit The reference value parameter and the corresponding specific symbol are stored in the parameter comparison table of the data storage device. If not, no action or notification to the specific user that the reference value (ie, the bid) is insufficient to be preferentially displayed.

In addition, the present invention can further provide a specific symbol display situation report for a specific user.

After a specific user has bidding through the network, the server can determine the representative of the coordinate unit (basic area unit) in the respective layer according to the coordinate point (basic area unit) specified by the specific user and its reference value parameter. Numeric parameters, which in turn generate recommendations, are sent to authorized clients of specific users. The suggested data includes, according to the reference numerical parameter, at what scale, in an embodiment, after obtaining the parameter comparison table, the server performs a preset operation, that is, calculates each map according to the data of each coordinate point. The representative numerical parameters for each of the regional units in the layer are stored in the data storage device 12 for recall.

In an embodiment, the numerical parameters as well as the particular symbols may be other content. For example, the numerical parameter is an integral value or level, and the specific symbol is a preset display mark or the like.

In another embodiment, the system 100 for displaying a specific symbol in a priority order in an electronic map further includes: the processing device 11 further includes a reduction processing module 111, an amplification processing module 112, and a movement Module 113. Please refer to Figure 9 for the specific structure.

When the request for reducing the map is included in the display electronic map request, the reduction processing module 111 corresponds each specific number of regional units adjacent to the current layer to one regional unit of the reduced layer, and the specific number is The specific number of the plurality of regional units represents the maximum value in the numerical parameter as a representative numerical parameter of the regional unit in the reduced layer, and the corresponding step is performed at least once to bring the reduced layer to the display layer.

When the request to enlarge the map is included in the display electronic map request, the enlargement processing module 112 equally divides each regional unit in the current layer, and the cutting step is performed at least once, so that each area unit after cutting is performed. The layer reaches the display layer, and obtains a representative numerical parameter of each area unit in the display layer according to data in the data storage device.

When the client 2 issues a mobile electronic map request, the request includes a destination range, and the mobile processing module 113 detects the number of the specific symbols that are not currently located in the target range, and if greater than 0, the slave data storage device In the range of obtaining the target in 12, in addition to the specific symbols still in the range of the purpose, sorted by the representative numerical parameters, and the specific symbols corresponding to the representative numerical parameters of the number of digits before the ranking are inserted, and the specific symbols are inserted. In the electronic map, it is sent to the communication device.
