利用居民地聚类和缓冲区分析完善道路网眼

对于十分规则的道路网(城市道路)来说构造网眼是十分容易的,且得到的道路网眼完整性较高,然而对于乡村道路,由于数据采集习惯或数据质量的影响,道路在居民地附近容易断开,导致计算机不能构造完整的网眼。本文针对这个问题,提出了利用居民地聚类和缓冲区分析的方法辅助道路网眼的构建,从而提高了乡镇郊区道路网眼的完整性,为采用网眼合并的方式进行综合的方法,以及各种基于网眼的空间分析提供了有效支撑。

Using Cluster and Buffer Analysis of Settlement to Help the Build of Road Meshes

It is easy to construct network and get high integrity for a city which has regular road network.For rural roads,however,the roads near the residence are usually disconnect due to the influence of habit in data acquisition or data quality,this will result in a fragmentary mesh.Aiming to solve this problem,a method based on the cluster algorithm and buffer analysis about building auxiliary road network is put forward in the article,which has improved the integrity of the country road network.It provides effective support for the method that generalize road by mesh merging and the spatial analysis based on mesh.
