THE DIGITAL ROCK ENGINEERING SYSTEM BASED ON 3D GIS TECHNOLOGY

underground development. The objective of such DRE system is to facilitate collaborative participation in underground engineering planning, feasibility study and construction management. The concept of DRE is first introduced to be followed by the design of the DRE system based on 3D GIS technology including: a) the framework of the DRE system; and b) the key technique in DRE system. Finally, this paper developed a prototype of DRE system according to the framework following these steps: a) Build an integrated relation database and file database; b) Develop a DRE system server side program named DataManger to manage the integrated database; c) Develop a true 3D DRE system client side program named 3DRock to visualize, query and analyze the integrated spatial data so that it could help the users to make an informed decision during the planning phase and construction phase; and d) Developed a WebGIS application for users to view, query and analysis the borehole information using internet
