In geography space, compared with spatial topological relations, spatial direction relations without doubt have more abroad applications and more closed to the human ’ s life, they should occupy more important position and exert greater effect in spatial information field 在地理空间中,与空间拓扑关系相比较,空间方位关系无疑是用途更广泛、更贴近人们生活的一种空间关系,在空间信息领域应该占有更重要的地位和发挥更大的作用。
