| 摘 要： | 系统介绍了基础地理信息跨尺度联动更新关键技术相关的规则体系,通过图层映射、几何对应、图面综合、要素取舍、关系协调等多套规则的有机结合,实现了变化更新信息的准确提取;同时开展了基于增量的要素编辑与自动化标注的约束性规则研究,并以1∶1万DLG数据联动更新1∶5万DLG数据为例,进行了跨尺度基础地理信息联动更新试验。

| Abstract: | This article introduces the rule architecture of key technology in the linkage updating of fundamental geographic information,describes the layer mapping,geometry correspondence,map synthesis,feature selection and spatial relationship coordination,et al,which can realize accurate extraction of change information.Research on constraint rules based on incremental element editing and automatic annotation are also carried out,and does the cross scale based geographic information linkage updating test with 1∶10000 DLG data linkage updating of 1∶50000 DLG data as an example. |
