Abstract
The topological relationship of the spatial data is very vital for addressing GIS data and spatial analysis, because the topological relationship makes it possible for us to define the spatial location of one geographical object according another without calculating the distance or using coordinates. Topological relationship built on 2D GIS has been developed nowadays, however in 3D GIS, there is no mature algorithm about the automatic structuring because of the complicated topological relationship. After a deep research about the automatic structuring algorithm in 2D surface (we call it levorotary algorithm), this essay will provide an algorithm based on patches, through which the relationship between patches and 3D objects will be built automatically, this algorithm lays the basis of spatial query and spatial analysis.
