If the map sheet data processing equipment of electronic map is in the object for executing the first map sheet of division in above-mentioned steps 103 When, a certain whole object in the object of the first map sheet is respectively divided into a certain subobject in n sub- map sheets, and adjacent son Tie point between object is object tie point, and n is the integer more than or equal to 2；Then when executing this step 104, for n The adjacent subgraph width of any two (such as the first subgraph width and second subgraph width) in subgraph width, the whole object is in the first subgraph Subobject in width and the second subgraph width is respectively the first subobject and the second subobject, the map sheet data processing dress of electronic map The object data for setting the first subgraph width of storage includes: the mark of the object tie point between the first subobject and the second subobject Information, the corresponding relationship of the identification information of the second level attribute and the second subobject of the second subobject；
The object data of second subgraph width includes: the mark of the object tie point between the first subobject and the second subobject Information, the corresponding relationship of the identification information of the second level attribute and the first subobject of the first subobject.One can be passed through in this way Information associated with the identification information of object tie point finds the subobject of adjacent subgraph width in the object data of subgraph width, into And determine the position of the object of each subgraph width, to recover the object of the first map sheet in first order electronic map.
Such as shown in Fig. 3, a urban road in the first map sheet is divided into 1 He of road in the subgraph width in city 1 The tie point of road 2 in the subgraph width in city 2, road 1 and road 2 is tie point a, the object of the subgraph width in such city 1 It include: the identification information of tie point a, the corresponding relationship of the identification information of the identification information and road 2 in city 2 in data；City 2 Subgraph width object data in include: tie point a identification information, the identification information of the identification information and road 1 in city 1 Corresponding relationship.
Further, the map sheet data processing equipment of electronic map can also when storing the object data of each subgraph width The identification information of corresponding subgraph width is accordingly stored, the identification information of each subgraph width can be identical, is all above-mentioned first map sheet Identification information.It and can also include the information such as the identification information of second level attribute in any second level data packet.
Step 105, the object data of the second map sheet is stored into corresponding second by the map sheet data processing equipment of electronic map In the second level data packet of grade attribute.
Further, the map sheet data processing equipment of electronic map can also record more after performing above-mentioned steps 104 The corresponding relationship of the identification information of the identification information and the first map sheet of a second level attribute, can thus learn the first map sheet The object data for the subgraph width that object is divided into is stored into the second level data packet of which second level attribute, and then can basis The object data of these second level data packet neutron map sheets obtains the object data of the first map sheet in first order data packet.
And the map sheet data processing equipment of electronic map can also record one second after performing above-mentioned steps 105 The corresponding relationship of the identification information of the identification information and the second map sheet of grade attribute, can thus learn the number of objects of the second map sheet According to being stored into the second level data packet of which second level attribute, and then the first order can be obtained from this second level data packet The object data of second map sheet in data packet.
Wherein, the identification information of second level attribute can be specific name or number of second level attribute etc., a certain map sheet Identification information can be map sheet label etc..
It is appreciated that map sheet data processing equipment available multiple second level electronics through the above steps of electronic map The second level data packet of map (i.e. the electronic map of second level attribute), and in a certain second level data packet include corresponding second The object data of multiple map sheets of grade electronic map.The map sheet data processing equipment of electronic map can be by these second level data Packet is stored into server, then one or more second level data packets can be sent to client by server, and client can be with The map sheet data processing of electronic map is realized by the following method, and flow chart is as shown in figure 4, specifically include:
Step 201, client obtains second level data packet, and obtains the identification information of map sheet and the mark of second level attribute The corresponding relationship of information, wherein the object data of multiple map sheets in the data packet of the second level including second level electronic map, it is any The object data of map sheet includes the data of each object of the map sheet in the identification information and second level electronic map of map sheet, and It further include the information such as the identification information of second level attribute in the data packet of the second level.Wherein second level electronic map is second level attribute Electronic map.
Specifically, for client when obtaining second level data packet, terminal user can operate client, so that client is aobvious Show user interface, on a user interface includes the select button for selecting any second level attribute, a certain when the user clicks (or it is more It is a) after the select button of second level attribute, client can initiate the to a certain (or multiple) second level attribute to server The request of secondary data packet.The second level data packet of client request can be sent to client by server in this way.
Further, client can also obtain the identification information of map sheet and the identification information of second level attribute from server Corresponding relationship, in this way if client determines that the identification information of a certain map sheet in a certain second level data packet is the first map sheet Identification information, and the identification information corresponds to the identification information of multiple second level attributes, client can execute step 202 to 204, such as The identification information of the corresponding second level attribute of the identification information of a certain map sheet of fruit (such as second map sheet), then client executing walks Rapid 205.
Step 202, client determines corresponding multiple second level attributes according to the identification information of above-mentioned first map sheet respectively Second level data packet in correlator map sheet object data the first storage location.
If the first map sheet corresponds to multiple second level attributes, due in above-described embodiment, at the map sheet data of electronic map Device is managed when storing second level data packet, is the object data difference for the multiple subgraph width for being divided into the object of the first map sheet It is stored into the second level data packet of corresponding second level attribute, and respectively includes each height in the object data of each subgraph width The identification information of map sheet, can be identical, all the identification information for the first map sheet.In this case, client is executing this step When 202, client can determine the second level data of multiple second level attributes respectively according to the identification information of above-mentioned first map sheet First storage location of the object data of correlator map sheet in packet.
Specifically, client can determine first map sheet in first order data packet institute according to the identification information of the first map sheet Position 1 in the first range (i.e. the range of first order electronic map) of covering, and any second level data packet is covered the Position 2 of two ranges (i.e. the range of second level electronic map) in above-mentioned first range be it is determining, due to each relevant The size of subgraph width is identical as the size of first map sheet, and the identification information of map sheet is also identical, then client can be according to upper Rheme sets the relative position between 2 and position 1, can be obtained any relevant subgraph width is covered in second level data packet Position 3 in two ranges, and then the first storage location of the object data according to the determining subgraph width in the position 3.
