摘要
提出了城市基本单元网格的概念,并对其划分原则进行了探讨。采用层次空间推理理论,设计了城市单元网格划分算法。实验结果表明,采用城市基本单元网格作为社会经济信息采集的基础,能通过基本单元网格的聚合得到不同层次的多级网格,从而实现社会经济信息的共享。
For the purpose of urban management, many spatial boundaries of urban areas such as administration boundaries, postal zones, urban planning zones, traffic analysis zones were designed by different departments for specific purposes, thus results in incompatible boundaries. The social statistics data based on these zones are difficult to use by other departments due to these incompatible spatial boundaries. The urban basic grid is proposed, and the division principle is detailed. An algorithm based on hierarchical spatial reasoning is designed to delineate the urban basic grid. An experiment is done to delineate the urban basic grid. The results indicate that the urban basic grid can be used to aggregate to higher level urban grid, and thus that the social statistics data collected by the urban basic grid can be shared among other departments.
