Abstract: The division method for cell cube is put forward based on Grid + Voxel.Further,the attribute of cell cube is analyzed,and quantitative models for attribute information extraction are also built.So the problem on cell cube is resolved,which includes the division for basic approximate homogenic three-dimensional spatial cell cube and the quantitative extraction for corresponding attribute information.Taking the central business district(CBD) of Beijing as an application case,the cell cube and the visualization result for underground space resource quality evaluation are showed.
