Description
Technical field
The present invention relates to the interlock method of electronic chart, more particularly, to a kind of side being capable of synchronous interaction many moneys electronic chart
Method.
Background technology
Internet era is it would be desirable to check some local or place place geographical position, we would generally open
Map application in computer or mobile phone scans for and checks；When we need to mark certain in oneself application or website
One place, we can be marked using the map label service that certain electronic chart manufacturer provides.
Electronic chart (Electronic map), i.e. numerical map, is to utilize computer technology, in a digital manner storage and
The map consulted.Baidu map, high moral map, Tengxun's map and Google Maps are the widest in current internet service and application
Four kinds of general electronic chart applications.It is provided which street, market, the geographical position of building and public bus network, travel route inquiry
With life-stylize Map Services such as planning.For China, Baidu, high moral map, Tengxun's map are native country map application,
Provide more detailed information for local life-stylize Map Services, but world map service is not provided, and Google Maps
Then provide worldwide Map Services.So, many times we need at least two maps to be used in combination.
But for geographic coordinate system (spheric coordinate system, longitude and latitude), the WGS84 coordinate system of Google Maps, and use
(GCJ-02 is the coordinate system of the GIS-Geographic Information System worked out by China's National Bureau of Surveying and Mapping to GCJ-02, and it is a kind of pair warp and weft degree
The AES of data, that is, add random deviation, and the various map systems (inclusion electronic form) of domestic publication are it is necessary at least
Using GCJ-02, geographical position is encrypted first) coordinate is encrypted；High moral map, Tengxun's map employ the GCJ- of standard
02 geographical position cipher mode；On the basis of Baidu map requires encryption in GCJ-02, and oneself has encrypted once (it to coordinate
Say in official document and be BD-09).Same coordinate information has carried out different encryptions so that same geographical position is in Baidu and height
Different coordinate datas are occurred in that, data can be difficult to share in De Deng map manufacturer.
Meanwhile, the geographic position data being used due to each map manufacturer is due to mapping methods, technical conditions
The renewal promptness of difference and map datum, the map geographic position data of each map manufacturer is presented in and can go out on respective map
Existing difference, such as display on a certain map for the same place occur in that deviation, a certain map geographical relief specifically and certain
One map is a piece of color lump, has newly repaiied a Qiao Yitiao road on some maps less than renewal；For another example, Google Maps provides
Worldwide every country and the very abundant map datum in city, abroad most countries and cities do not have
Covered by domestic map manufacturer and lead to using restriction.

Electronic chart, i.e. numerical map, is to utilize computer technology, the map storing in a digital manner and consulting.Mutual
In the networking epoch, a lot of electronic chart manufacturers have published the map software development kit (SDK) of oneself, facilitate internet to answer
Developer is based on oneself map exploitation electronic chart and applies and easily obtain geographical location information.And each family is electronically
The SDK that figure manufacturer issues all may be only available for oneself map, does not accomplish in the aspect calculating identification instruction execution operation
Unified.
And the inventive method is by creating an electronic chart controller that can be identified interactive instruction by computer unification,
Pass through to create electronic chart and the phase such as various actions, interaction, data, result produced by operation electronic chart computer-chronograph
The instruction of the computational methods data closed carries out abstract, interface, standardization, in application process, such as needs integrated use A electricity
Sub- map, then according to data-interface and the interactive instruction of the standard set by controller reality and interface example A map, so collect
Become B map, C map etc., and all interactive actions of all maps are monitored.When computer listens to some ground legend
As A map is performed some interactive instruction by operation, the action data that recording interactive instruction produces, and by data and instruction
B map is separately converted to by the method for controller, respective action data that C map can identify, last executed instruction, reach
Produce the effect of linkage to synchronous A map operation.So all integrated map locations, the map landforms shown etc. are all always
's.
Implement the embodiment of the present invention, have the advantages that：The present invention's is capable of synchronous interaction many moneys electronic chart
Method by the linkage of multiple electronic charts so that one electronic chart of operation can be seen that multiple electronic charts are carried out simultaneously
Display, comparative strong, and the data not having on an electronic chart can directly see another electronic chart, very just
Just.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
