Operation principle of the present invention is：
Web GIS service device mainly handles the three-dimensional map tile service request that application end is sent please with geographic information data
Ask, geographical space information on services obtained from GIS server according to the service request of user, map tile service request can first from
Corresponding map tile data are read in the map tile data buffer storage of webpage Web server and return to user；If in caching
Without data, then corresponding Web GIS service component can be called to obtain map tile data in real time from backstage GIS server and returned
Back to user.By the application of WebGIS technologies, departing from traditional C/S model, not only three-dimensional display spatial object
Parallel relation and vertical relation, there is provided the direct access module of user browser, three-dimensional scene images are shown on a web browser, and can
Carry out three dimensions operation and analysis.WebGL belongs to open-standards, has open, cross-platform characteristic, has obtained numerous masters
The support of browser is flowed, it is added by being bound with OpenGL ES 2.0 JavaScript scripts using the graphic hardware of bottom
Fast function, rendering for three-dimensional scenic is realized, eliminated using webpage Rendering Plug, make three dimensional object shows more quick, stream
Freely.
Due to the complexity of spatial data, Web GIS service device is difficult in the case of existing bandwidth quick response and quick
Accordingly result is returned to, user's request time that this allows for user terminal is significantly elongated, can not meet that user is quick by browser
Access the demand of data.And Web GIS service device cluster then can effectively handle the problem, accelerate data extraction and data processing
Time, shorten service request-response time.Server cluster mainly is formed by multiple server nodes, request is taken
Business carries out cluster management, loads very much, increases serious forgiveness, realizes the thought of " trading space for time ", improves Web GIS service
The ability of parallel processing.
3 d model library handling process is：
1) existing 3 d model library is handled using partitioning algorithm, three-dimensional model library is divided into multiple small stand
Cube structure.
2) the vector conversion of threedimensional model：The modeling of spatial data three-dimensional building is completed, spatial model is formed, model is entered
Row spatial gridding, three-dimensional vector group is formed, based on this, complete model data two dimensionization and decompose, obtain block model member
Element, extraction parsing is carried out to datagraphic, obtain bivector panel data, completed vector layer and decompose refining data acquisition work
Make.Method of Data Organization is exactly to be reached each small legislation body Model contacts list 1) decomposed using specific data format.
3) vectorization Web service is exempted from plug-in unit and shown：User can obtain and make by oneself by setting personalized characteristic in system
Adopted vector layer displaying.By user individual characteristic, webpage Web browser is asked to webpage Web server, uses Spatial Cable
Draw, obtain specific place and its characteristic of user's selection, information iteration is carried out to vector layer, obtains customized three-dimensional information
Data, 3D landform and characteristic details, internal information are shown on webpage Web browser.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
