Administration gets up also quite cumbersome, and can not support cross-platform.With the transition of Internet era, mobile interchange becomes main trend
Under, traditional three-dimensional applications have been unable to satisfy needs, it is therefore desirable to which one is light-duty, and popular three-dimensional applications that can be cross-platform are come
Replace traditional three-dimensional applications.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of three-dimensional GIS platform architecture systems, using internet as base
Plinth, browser are the WebGIS three-dimensional applications of terminal；The present invention can solve too fat to move client and dispose cumbersome problem, and
Can preferably support it is cross-platform, using the unique render mode of WebGL, so that the bandwagon effect under framework of the present invention is not weaker than biography
The three-dimensional applications of system make the experience of user be multiplied.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of three-dimensional GIS platform framework system
System, including client and server terminal, the client use WebGL technology and show various geographical space numbers to user
According to the client is communicated by Internet network and server terminal；The server terminal include Web server and
GIS database, and be two-way electric connection between Web server and GIS database；Web server is applied as WebGIS
Main carriers, for being responsible for the access and publication of application software；GIS database is used to store the spatial data of various formats.
As present invention further optimization technical solution, the client is one of plate or mobile phone.
As present invention further optimization technical solution, the server terminal is mainly responsible for multiple client and provides
Geographical spatial data, server end can by the spatial data of different-format in database, data file in the form of json to outgoing
Cloth.
(3) beneficial effect
The present invention provides a kind of three-dimensional GIS platform architecture systems.Have following the utility model has the advantages that the three-dimensional GIS platform frame
Construction system, based on internet, browser is the WebGIS three-dimensional applications of terminal；The present invention can solve too fat to move client
With dispose cumbersome problem, and can preferably support it is cross-platform, using the unique render mode of WebGL, so that framework of the present invention
Under bandwagon effect be not weaker than traditional three-dimensional applications, so that the experience of user is multiplied；Meanwhile the present invention also has and following has
Beneficial effect: popular: the development of random internet, so that allowing GIS to have more chances is public service；It is cross-platform: traditional GIS
Manufacturer needs to provide the GIS software of corresponding version respectively to different operating system, and the carrier that the present invention applies is web browsing
Device, as long as so terminal device can run browser and access GIS service, to be readily implemented cross-platform.
