摘要
文中通过分析DLG数据整合过程中遇到的居民地地名层缺少地名编码、植被注记混乱、面域水系与线形水系的HYDC码不统一等问题,提出一种基于要素空间关系的自动整合方法,以云南省1∶10 000DLG数据整合为例,借助ArcGIS的二次开发实例,验证该方法的可行性。
Aiming at the problems that residential places lack of name code ,vegetation note jumbles and HYDC code of surface field water differents form HYDC code of linear water ,this paper puts forward a kind of automatic integration method based on feature spatial relations in DLG data .Taking 1∶10 000 DLG data integration in Yunnan province as an example ,this paper verifies the feasibility of this method with an instance built by the secondary development of ArcGIS .
