| 摘 要： | 针对森林资源二类调查内业流程,利用空间拓扑分析,解决图斑面属性赋值的难题,并且分析其一一对应关系,记录查错信息。在VB编程环境下,采用ArcEngine组件库,提出林地图斑拓扑查错算法流程,按照空间包含关系,将属性点记录的属性信息一一赋值到满足条件的图斑面内,自动获取包含属性信息的林地图斑面数据。

| Abstract: | For the process of official work in forest management inventory, the problems of areal polygons＇ attribute assignment by spatial topology analysis has been solved. This paper analyzed those one to one corresponding relationships, recordsed checking information. Using ArcEngine component library under VB coding environment, we proposed the algorithm for areal polygon topology check. According to the geospatial containing relationship, the information of attribute points were assigned to the areal polygons one by one. As a result, we achieved forest subcompartment containing attribute informa- tion automatically. |
