An underground space object-oriented three-dimensional hybrid spatial indexing method


In order to improve the efficiency of three-dimensional topological operations and specialized geographical model calculation, the efficient index mechanism to three-dimensional data is necessary. Taking into account of the underground space, the extending space of physical objects in the horizontal direction is far larger than the vertical direction. Thus… (More)
