基于障碍约束空间聚类的地形单元划分

Terrain Unit Division Based on Spatial Clustering with Obstacle Constraints

地形单元划分是地理环境分析的基础。为了解决凭经验划分地形单元问题，提高地形单元划分效能，提出了综合采用拓扑构建技术和约束空间聚类技术来划分地形单元，旨在通过计算机辅助决策，自动划分出理论上最佳的地形单元，服务地理环境认知。试验表明，障碍约束空间聚类技术能较好解决地形单元的自动划分问题。

Terrain unit division is the foundation of geography environment analysis. In order to improve the efficiency of terrain unit division, this paper puts forward the method of terrain unit division by applying topological relation construction and spatial clustering with obstacle constraints technology, which aims at dividing the best terrain unit automatically and serving the geography enviroment cognition through computer - aided decision. Experiments indicate that automatic division of terrain unit can be achieved by spatial clustering with obstacle constraints technology.
