The invention discloses a Web3D 
network communication platform and a construction method thereof, and the method comprises the steps: integrating unmanned aerial vehicle data, 
remote sensing data, GISdata, DEM and other multi-source, multi-scale and multi-dimensional data by means of public data and related news information of a Chinese 
geological survey bureau, and building a multi-dimensional display interface of the communication platform. A 3D model is embedded in the website by adopting a WebGL. 
JavaScript is used for 
processing interaction operation between the webpage front end and a user, and the functions of POI point online construction, data uploading, 
online forum discussion, positioning, multi-dimensional 
virtual reality interface display and the like are achieved. A rear-enddatabase stores user POI data, forum data and related data, so that the user can check the data in real time, and knowledge transmission and sharing are realized to a great extent. The Web3D networkcommunication platform has a 
field practice communication function, and 
topographic map cognition, field 
route geological examination and mapping, typical geological phenomenon research and analysis and the like can be carried out in combination with practice requirements; and a 
traditional classroom education mode is broken through.
