| 摘 要： | 土地利用现状图的数字化是建立土地利用数据库的主要技术手段之一,图斑作为土地利用现状图的主要要素,其矢量化方法的优化与否不仅关系着整个数据采集的进程,而且还将影响到土地信息系统的稳定与否。文章针对传统的图斑矢量化引起的面域交叉、对象撕裂等问题研究提出了基于弧段的图斑矢量化方法,并通过线状地物与图斑的叠合分析,建立线状地物...

| Abstract: | The digitization of land use status map is one of methods to establish land use database.Patches are the main elements in land use status map.The optimization of vectorization method is not only related with the whole procedure of data collection,but also influences the stability of land information system.Aiming at the problems in the process of vectorization of patches,such as region intersection and object splits,this paper put forward a method for patches vectorization based on arcs.Through the overlapp... |
