Mining Land Reclamation Information System Based on 3D GIS

Land reclamation of mining area is a complex information system. To promote land management effectively and achieve the goal of land resources use, land reclamation information system was established based on 3D GIS. Land reclamation system based on spatial database to manage multi-source heterogeneous data was proposed in this article, whose core was to establish the matter-element model, visualization and 3D spatial analysis of land reclamation scheme. The structure and function and key technologies of the 3D GIS system were also studied in this paper, which emphasized on modeling method in land reclamation scheme according to matter-element model. The results show that this system can integrate the multi-source heterogeneous spatial data and related properties data into the whole body, demonstrate graphical visualization and analyze compositely. So using this system for mining land reclamation management has strong practicability.
