The invention discloses a WebGIS three-dimensional lunar 
system based on ActiveX. The WebGIS three-dimensional lunar 
system based on the ActiveX is characterized in that the 
system comprises a 
client-side browser, a webpage 
WEB server, a WebGIS 
server, a GIS 
server cluster and a data 
server, the 
client-side browser is used for data displaying, data acquiring and 
data cache, providing an interactive interface, drawing a three-dimensional model and inserting a three-dimensional scene into the browser by means of the ActiveX control technology, the webpage 
WEB server is used for responding to page requests sent by the 
client-side browser and feeding back a page response to the client of the browser, the WebGIS server is used for providing service catalogues and tile services for the client of the browser, the GIS server cluster is used for providing underlying GIS supporting services including universal services, storage and access of 
geographic space information, manufacturing and releasing of maps and load balancing, and the data server is used for storing geographic 
information data. According to the WebGIS three-dimensional lunar system based on the ActiveX and a realizing method of the WebGIS three-dimensional lunar system, the three-dimensional lunar scene is inserted into a webpage, namely lunar data are displayed in a three-dimensional mode with the B / S structure, and the three-dimensional lunar scene can be browsed directly by a user through the browser.
