【Description of the drawings】
Fig. 1 is the schematic flow sheet of the electronic map information processing method of an embodiment of the present invention；
Fig. 2 is the schematic flow sheet of the electronic map information processing method of another kind embodiment of the invention；.
【Specific embodiment】
Preferred embodiment to inventing below is described in further detail.
Electronic chart has multiple zoom levels, and level of zoom is lower, and its map scale is bigger, but different zoom level
Geographic range represented by other electronic chart is identical.The electronic chart of each level of zoom, by the ground of corresponding number
Figure tile is constituted, and the lower electronic chart of level of zoom, the number of its map tile for including are more, the resolution of each tile
It is higher.
Client may pass through the different electronic chart of browser or specific map software flow, such as electronic chart
A and electronic chart B (such as Baidu map and Google Maps), generally, different electronic charts has different level of zoom, or
Person, even if having identical level of zoom number, the map tile center of each electronic chart is also impossible to difference, thus results in
In same level of zoom, identical longitude and latitude is belonging respectively to different map tiles in electronic chart A and electronic chart B.
S1. when client end detects user browses electronic chart, by the level of zoom number of now electronic chart A,
Map tile center and the corresponding tile number of each level of zoom are sent to server.
If S2. user side detects user and markup information is labeled on electronic chart A, for example, in cartographic information
The area marking address points for relatively lacking, or mark track route (route can be regarded as and is made up of a series of point), then will
Now mark address points or the geographical coordinate of track route is sent to server.
S3. server is according to the geographical coordinate of markup information, map tile center and corresponding watt of each level of zoom
Piece number, calculates under different zoom rank, which tile belonging to these markup informations, for example, in the first level of zoom
Under belong to map tile a, belong to map tile b etc. under the second level of zoom, and by markup information, level of zoom, affiliated
The corresponding informance of map tile three be stored in server.
S4. electronic chart A is operated when client detects user, for example, zooms in or out, and enter certain
After level of zoom m, level of zoom m is sent to into server, request server sends the mark letter corresponding with level of zoom m
Map tile n belonging to breath.
S5. map tile n described in markup information is sent to client by server；
S6. client calculates map tile location of pixels of the markup information in map tile n, i.e. map tile coordinate,
For example, calculate on certain certain pixel of mark point in map tile n, then one is drawn thoroughly on the electronic chart
Bright figure layer, wherein, outside the position of transparent figure layer markup information only on map tile n is corresponded to not is transparent, remaining
All it is transparent, to prevent the information can be caused to cover of electronic chart A.
If S6. client detects user and browses electronic chart B, by the level of zoom number of now electronic chart B,
Map tile center and the corresponding tile number of each level of zoom are sent to server.
S7. then server, by the markup information on electronic chart A for obtaining in step s 2, recalculates acquisition and exists
The tile belonging to the markup information under each rank on electronic chart B, then by markup information, level of zoom, affiliated
The corresponding informance of map tile three be stored in server.
S8. electronic chart B is operated when client detects user, for example, zooms in or out, and enter certain
Level of zoom m ' after, by level of zoom m ' is sent to server, and request server sends and level of zoom m ' corresponding mark
Map tile n belonging to note information '.
S5. server is by map tile n described in markup information ' it is sent to client；
S6. client calculates markup information in map tile n ' on map tile location of pixels, the then electronics again
Draw on map B and cover a transparent figure layer, wherein, the transparent figure layer is only in correspondence map tile n ' on markup information
Outside position is not transparent, remaining is all transparent, to prevent the information can be caused to cover of electronic chart B.
So, even if the different electronic chart of Client browse, client can generate one on the electronic chart
Accurate markup information, and need not repeat to send markup information to server, such that it is able to save certain data traffic
With the efficiency for browsing generation figure layer.
The switch that transparent figure layer (static figure layer) shows can be shown on the interface of electronic chart, to facilitate user to select
Whether the transparent figure layer is loaded.
Above content is with reference to specific preferred implementation further description made for the present invention, it is impossible to assert
The present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of without departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention by
The scope of patent protection that the claims submitted to determine.
