Description
Technical field
The present invention relates to GIS-Geographic Information System (GIS, the Geographic InformationSystem) technical field in the internet, especially relate to a kind of GIS-Geographic Information System professional system, access means and method thereof be provided.
Background technology
GIS-Geographic Information System (GIS; Geographic Information System); Be that multi-door science such as a collection computer science, information science, geography are the new branch of science of one, it is under the support of computer software and hardware, and utilization systems engineering and information science are theoretical; Scientific management and analysis-by-synthesis have the geodata of space intension, so that the system that planning, management, decision-making and research institute is needed spatial information to be provided.
Be accompanied by the development of mobile Internet, on portable terminal, realize more and more urgent based on the business demand of GIS network capabilities.As shown in Figure 1; Be Traditional GIS networking architectural schematic, wherein location service management platform (LBMP, LBS Based service Manager Platform)/location service access platform (LBAP; Location Based service Access Platform) node is linked into GIS node and Location Service Platform (LSP; Location-based service platform) node, (SP ServiceProvider) is connected with the LBMP/LBAP node service provider.
As shown in Figure 1, the interface between SP and the LBMP/LBAP node is the Gv interface, and the interface between LBMP/LBAP node and the GIS node is the Li interface, and the interface between LBMP/LBAP node and the LSP node is the Le interface.The location-based service that SP uses Map Services that the GIS node provides and LSP node to provide through the Gv interface that calls the LBMP/LBAP node and provide.
Use through the Gv interface that calls the LBMP/LBAP node and provide in the practical business scene of the location-based service that Map Services that the GIS node provides and LSP node provide at SP, the application server of SP sends the geography information request through HTTP POST mode usually and arrives the LBMP/LBAP node.Solicited message and response message through the Gv interface generally comprise two parts: information header (header or context) and imformosome (body), wherein comprise some information that are used for authentication etc. in the information header, and then comprise the content of concrete request in the imformosome.The imformosome content is write based on the XML form usually particularly.
Generally speaking,, all need the program development personnel to understand concrete Gv protocol stack of the interface, and adapt to according to concrete Gv protocol stack of the interface and to write through the solicited message and the response message of Gv interface.But the Gv interface comprises a plurality of service interface set at present; Understand each service interface that the Gv interface provides fully; And write the solicited message and the response message of adaptation respectively to every kind of service interface; For the program development personnel, be to take time and effort, promptly need the protocol stack of program development people system's study Gv interface, the Gv interface is carried out just writing various solicited messages and response message after system's understanding; Thereby cause the program development efficiency ratio lower, and then influence professional the carrying out and use of GIS.
Summary of the invention
The embodiment of the invention provide a kind of GIS-Geographic Information System professional system, access means and method thereof be provided; Write solicited message and response message to avoid in the prior art program developer to understand the Gv protocol stack of the interface and adapt to; Inefficiency, thus the professional problem of carrying out and using of GIS influenced.
