Study of the Combined Cata Structure on Linear Quadtree & Linear Octree in Mine Geographic Information System

Chen Daoqing;Lan Xiaoji (Department of Scientific Research ) (Department of Construction )  
Analyze the Characteristics of the linear quadtree and linear octree and describe the linear octree encoding based on the decimal system. The data structure of the linear octree based on quadtree is presented to meet the demand of the spatial cover analysis of three-dimensional objects and two-dimensional objects.The result of the experiment shows that the data structure is useful for integrating the MGIS with DEM and RS.
