Step 101, acquiring basic business data.

Specifically, the data types of the obtained basic business data include point data types, line data types, and surface data types. Basic business data can be obtained from pre-stored tables, or real-time from data streams.

Step 102, converting the basic business data into spatial data, and determining the data type of the spatial data, the data type includes point data type, line data type and area data type.

Specifically, the basic business data cannot be directly added to the electronic map layer, but the basic business data needs to be converted into spatial data conforming to the electronic map data format. The data types of the spatial data conforming to the electronic map format are also divided into: point data type, line data type, and area data type. The data type corresponding to the basic business data is determined as the data type of the spatial data corresponding to the basic business data.

Step 103, adding the spatial data to layers corresponding to the data types, the layers are point layers, line layers and area layers, and the layers are preloaded into the electronic map.

Specifically, because the data of the electronic map is generally stored using vector data, geometric figures such as points, lines (composed of a series of points), and surfaces (composed of at least three lines) are used to represent objective objects when storing vector data, so , the electronic map can include point layer, line layer and area layer. In the embodiment of the present invention, after the data type of the spatial data is determined, the spatial data is added to a layer corresponding to the data type, thereby realizing updating of the electronic map data. After the data type of the spatial data is determined in the embodiment of the present invention, the spatial data is added to the layer corresponding to the data type in real time according to the data type of the spatial data. The specific method for adding spatial data to the electronic map layer is an existing method, and will not be repeated here.

When the determined data type of the spatial data is a point data type, the point spatial data is added to the preloaded point layer, and when the electronic map is updated to present to the user, the point layer with the point spatial data added is generated The point corresponding to the point spatial data, and present each point in the electronic map for users to view; when the determined data type of the spatial data is a line data type, add the line spatial data to the preloaded line layer In , when the electronic map is updated to present to the user, the line layer added with the line spatial data connects each point contained in the line spatial data to generate a line, and presents the line in the electronic map for the user to view ; When the data type of the determined spatial data is the area data type, add the area spatial data to the preloaded area layer, and add the area layer of the area spatial data when updating the electronic map to present to the user The points included in the surface space data are connected in sequence and rendered to generate a surface area, and the surface area is presented on the electronic map for users to view.

In the embodiment of the present invention, the basic business data includes: the location information of the base station in the mobile communication system, the coverage area information of the base station, the location information of the business hall of the network operator, etc., and may also include other data with special requirements for the business , there is no limitation here. Wherein, the updated electronic map data is to update the basic business data of the business layer in the electronic map, and the business layer of the electronic map includes the pre-loaded point layer, line layer and surface layer, which are updated in the embodiment of the present invention. It is the data in the operational layer of the electronic map. The business layer is a layer that displays the basic business data of the communication industry in the electronic map, and the data displayed in the business layer are all basic business data.

In the embodiment of the present invention, since the three layers of point layer, line layer and area layer are loaded in the electronic map in advance, it is only necessary to restart the electronic map service once. If the electronic map data needs to be updated later, only the Just add the data to the corresponding layer, so that to a certain extent, the purpose of automatically updating the electronic map data without closing the electronic map service is achieved, and the real-time performance of updating the electronic map is improved.

Preferably, in step 102, converting the basic business data into spatial data specifically includes:

The latitude and longitude information corresponding to the basic service data is determined, and data vector processing is performed on the latitude and longitude information through a preset object model to obtain spatial data corresponding to the basic service data.

Among them, the basic business data includes the latitude and longitude information corresponding to the basic business data. According to the latitude and longitude information, the data vector processing is performed on the latitude and longitude information through the preset object model to form non-topological vector data (shapfile). Process to obtain the spatial data corresponding to the basic business data. The embodiment of the present invention can automatically convert basic service data into spatial data without resorting to other conversion tools.

Preferably, the following methods can be used to determine the data type of spatial data:

When it is determined that the latitude and longitude information includes a set of latitude and longitude, it is determined that the data type corresponding to the basic business data is a point data type; it is determined that the latitude and longitude information includes multiple sets of latitude and longitude, and at least two different sets of latitude and longitude are included in the multiple sets of latitude and longitude Longitude and latitude, and when the first group of longitude and latitude and the last group of longitude and latitude are different, it is determined that the data type corresponding to the basic business data is a line data type; it is determined that the longitude and latitude information includes at least four groups of longitude and latitude, and the first group of longitude and latitude and the last When the longitude and latitude of the group are the same, it is determined that the data type corresponding to the basic business data is the plane data type. Other methods in the prior art may also be used to determine the data type of the spatial data. Wherein, two sets of the same longitude and latitude refer to that one set of longitudes is the same as the longitude of the other set, and that one set of latitudes is the same as the other set of latitudes.

Specifically, according to the latitude and longitude information corresponding to each basic business data in the basic business data, the data type of the spatial data corresponding to the basic business data is determined. latitude, if the latitude and longitude information of a certain basic business data is (110, 40), then the data type of the spatial data corresponding to the basic business data is a point data type; if the latitude and longitude information of a certain basic business data is (110, 40, 111, 41, ..., 115, 40), that is, the first group of longitude and latitude (110, 40) in the longitude and latitude information is different from the last longitude and latitude (115, 40) and includes at least two groups of different longitude and latitude, then the basic business data The data type of the corresponding spatial data is the line data type; if the latitude and longitude information corresponding to a certain basic business data is (110, 40, 111, 41, ..., 112, 42, 110, 40), that is, the latitude and longitude information includes at least Four sets of longitude and latitude, and the first set of longitude and latitude is the same as the last set of longitude and latitude, then the data type of the spatial data corresponding to the basic business data is the surface data type.

Among them, the pseudocode corresponding to adding the spatial data whose data type is point data type to the preloaded point layer is:

insert into point layer table name (spatial field, ordinary field) values (st_point (longitude, latitude), other data)//where st_point is the function of processing complex SQL point objects;

The pseudocode corresponding to adding the spatial data whose data type is line data type to the preloaded line layer is:

insert into line layer table name (spatial field, common field) values (st_line (longitude, latitude, longitude, latitude), other data)//where st_line is the function for processing complex SQL line objects;

The pseudo-code corresponding to adding the spatial data whose data type is the area data type to the preloaded area layer is:

insert into surface layer table name (spatial field, common field) values(st_polygon(longitude, latitude, longitude, latitude, longitude, latitude, longitude, latitude), other data)//where st_polygon is the function for processing complex SQL surface objects .

Specifically, the basic business data of the area data type may or may not include latitude and longitude information, and for the basic business data of the area data type including the latitude and longitude information, determine the latitude and longitude information corresponding to the basic business data, specifically including: The latitude and longitude information of the basic business data is extracted from the basic business data.

For the basic business data of the area data type that does not include latitude and longitude information, then determine the latitude and longitude information of the basic business data, as shown in Figure 2, specifically including:

Step 201, draw the first area block of the basic service data.

Specifically, for the basic business data of each plane data type, the basic business data corresponds to an area block, and the first area block corresponding to the basic business data is manually drawn according to the basic business data.

Step 202, determining each second area block of each level in the electronic map.

Specifically, starting from the highest-level electronic map layer, each second area block in this level is determined. If the electronic map level is divided into provincial, city, county, and township levels, the electronic map level is from high to low. They are provincial level, city level, county level, and township level. The electronic map layers at each level are composed of multiple road layers, and the multiple road layers include highway layers, national road layers, and provincial road layers. road layer, street layer, etc., and each second area block is an area block corresponding to the intersection of at least three roads.

Step 203, determining a second area block matching the first area block among the second area blocks.

Specifically, the first area block is matched with each second area block one by one. Wherein, if none of the second area blocks matches the first area block, it is determined that the basic service data corresponding to the first area block is invalid data, and the operation of adding the invalid basic service data to the electronic map is not performed. Determining the second area block that matches the first area block among the second area blocks, specifically by determining the second area block that matches the area of the first area block and matches the shape of the first area block among the second area blocks. Two area blocks. The matching second area block may also be determined in other ways.

Step 204, determining the latitude and longitude information of the matched second area block as the latitude and longitude information of the basic service data.

Wherein, if a second area block matching the first area block is found at a certain level, the latitude and longitude information of the matched area block is determined as the latitude and longitude information of the basic service data corresponding to the first area block. Specifically, it can be determined that the matching is successful by determining that the areas and shapes of the first area block and any area block of the second area blocks are the same or similar, and other methods can also be used to determine that the matching is successful, which is not limited here.

Utilizing the embodiment of the present invention, it is possible to determine the latitude and longitude information of the basic business data of the surface data type, thereby determining the spatial data corresponding to the basic business surface data according to the determined latitude and longitude information, and then adding the spatial data to the electronic map to realize Online real-time update of electronic map data.

Based on the embodiment shown in FIG. 2 , preferably, in step 203, the second area block matching the first area block among the second area blocks is determined, as shown in FIG. 3 , specifically including:

Step 301, determine the minimum circumscribed rectangle corresponding to the first area block, and each minimum circumscribed rectangle corresponding to each second area block.

The specific way of determining the minimum circumscribed rectangle is an existing way, and will not be repeated here. Each second area block corresponds to a minimum circumscribed rectangle.

Step 302 , using the small grids with a set length and a set width as templates, respectively divide the first minimum circumscribed rectangle and each second minimum circumscribed rectangle into small grids.

Specifically, the first minimum circumscribed rectangle is divided into several small grids with a set length and a set width, and each second minimum circumscribed rectangle is also divided into several small grids with a set length and a set width . The first area block corresponds to a certain number of small grids in the first smallest circumscribing rectangle, and each second area block corresponds to a certain number of small grids in its corresponding second circumscribing rectangle.

Step 303, determining the number of small grids occupied by the first area block, and determining the number of small grids occupied by each second area block.

Specifically, after the first minimum circumscribed rectangle is divided into small grids, the number of small grids occupied by the first area block in the first minimum circumscribed rectangle can be determined. Similarly, each second minimum circumscribed rectangle is divided into small grids After division, the number of small grids that each second area block occupies in the corresponding second smallest circumscribed rectangle can be determined.

Step 304, determining a second area block in each second area block that matches the number of small grids occupied by the first area block and matches the shape of the first area block.

Specifically, firstly, determine the second area block that matches the number of small grids occupied by the first area block; secondly, determine the second area block that matches the number of small grids occupied by the first area block A second area block that matches the shape of the first area block; or, first determine the second area block that matches the shape of the first area block; secondly, determine the second area block that matches the shape of the first area block A second area block that matches the number of small grids occupied by the first area block.

In this preferred embodiment, the second area block matching the first area block is determined by performing small grid division on each area block.

Preferably, in each second area block, determining a second area block that matches the number of small grids occupied by the first area block and that matches the shape of the first area block specifically includes: in each second area block A second area block whose difference with the number of small grids occupied by the first area block is within a set threshold range and which has the same shape as the first area block is determined among the area blocks.

Specifically, each small grid in each minimum bounding rectangle corresponds to a number, wherein the rules for numbering the small grids in each minimum bounding rectangle are the same, the shape of the first area block is the same as that of the second area block, It specifically includes: the numbers of the small grids corresponding to the first area in the first smallest bounding rectangle are the same as the numbers of the small grids corresponding to the second area block in the second smallest bounding rectangle, and the shape of the first area block Same shape as the second area block.

Specifically, in step 103, before adding the spatial data to the layer corresponding to the data type, it also includes: determining the regional attribute information of the basic business data corresponding to the spatial data, so as to know the region to which the basic business data belongs, so that The basic service data is displayed in the region corresponding to the electronic map to present to the user.

The following methods can be used to determine the geographical attribute information of each basic business data:

First, the spatial data corresponding to the basic business data is matched to the geodetic coordinate system such as the Xi'an 84 geodetic coordinate system. Through the matched spatial data, different buffer operations are performed on the spatial data of different data types according to different data types. Specifically, the BUFF operation is performed on the spatial data within the range of the set BUFF (buffer), and the BUFF operation can be realized by starting the spatial data buffer function. The pseudo code is as follows:

Function buffGeometry(geometry):Geometry{

Geometry geo＝Server.buffGeometry(geometry);//Generate element BUFF object

return geo; }

Secondly, determine the topological relationship (including intersection) between the BUFF results corresponding to the spatial data of different data types and the area data of the area layer (including the provincial boundary layer, city boundary layer, county boundary layer, etc.) in the base map. relationship, separation relationship, inclusion relationship). Wherein, the base map is a part of the electronic map, and the data in the base map will not be updated, usually including administrative regions, forests, water systems, roads, POI (Point of Interest, point of interest), etc. Geographic polygons refer to the real spatial location areas in the base map, generally composed of national boundaries, provincial boundaries, city boundaries, county boundaries, etc., and belong to fixed index layers in the base map.

Again, when it is determined that the BUFF corresponding to a certain spatial data is included in the area where the regional layer in the base map is located, the basic business data corresponding to the spatial data has the attributes of the area. For example, the BUFF corresponding to a certain spatial data is included in For a city under a certain province in the basic spatial information geographic layer, the authority of the basic business data corresponding to the spatial data belongs to the city under the province; determine the BUFF corresponding to a certain spatial data and the area in the basic map When the region where the layer is located intersects or separates from each other, the basic business data corresponding to the spatial data does not have the attribute of the region.

Among them, according to the attribution of the geographical location information of the spatial data, the multiple attribute information of the basic business data corresponding to the spatial data can be obtained. For example, it is an attribute information that the basic business data corresponding to a certain spatial data belongs to a certain province. The business data specifically belongs to a certain city in a certain province, which is another attribute information. According to the comparison result of the BUFF result and the regional plane where the regional layer in the basic map is located, the regional attribute information owned by each basic business data can be obtained.

Further, the visible level of the basic business data on the electronic map can be determined according to the geographic attribute information of the basic business data, that is, the access level authority information of the basic business data, so as to determine which level of the electronic map to display the basic business data to present to the user, specifically:

For each basic business data, according to the regional attribute information of the basic business data, the visible level of the region to which the basic business data belongs in the electronic map (the visible level in the slice level of the electronic map) is obtained from the configuration file of the electronic map , so that the visible hierarchy of the basic business data is consistent with the visible hierarchy of the region to which the basic business data belongs by default. The specific implementation pseudo code is as follows:

Function setMapLayerLevelFilter(){

map.enableLayerLevelLocaltion(number level);//Enable the hierarchical visible range filtering method for the layer, and the default activation is consistent with the base map};

Further, the map access regional authority of the basic business data in the electronic map can be determined according to the regional attribute information of the basic business data, specifically:

For each basic business data, according to the regional attribute information of the basic business data, the regional configuration table information is obtained from the authority configuration table of the electronic map; and according to the regional attribute information of the basic business data, the basic business data is hidden and Display settings, that is, if the visible range of the current map does not include the basic business data, the basic business data will not be loaded, and the basic business data will not be displayed on the electronic map. If the visible range of the current map includes the basic business data , load the basic business data and display the basic business data on the electronic map. The specific implementation pseudo code is as follows:

Function setMapLayerFilter(){

map.enableLayerLocaltion();//Start the location-based filtering method for the layer}

Specifically, the above-mentioned method for determining the regional attribute information of each basic business data, the method for determining the visible level of the basic business data on the electronic map according to the regional attribute information of the basic business data, and the method for determining the basic business data according to the regional attribute information of the basic business data The methods for accessing the regional authority of the map in the electronic map are all existing technologies, and will not be described too much here.

Specifically, when a request to access the basic business data is received outside the region to which the basic business data belongs, the access request is rejected, that is, access outside the region to which the basic business data belongs is not allowed The basic business data. For example, if some basic business data belongs to province A, province B does not have the right to access the basic business data.
