摘要
1∶1万DLG数据内业编辑是以全数字摄影测量系统采集的数据为基础,根据外业调绘成果对采集的数据进行内业编辑,并依据相关技术规定和作业规范要求对各类要素及相互之间的关系、数据的分层、各类要素数据的拓扑关系和点线面的相互关系进行正确表示。本文结合生产实践经验,探讨了内业在1∶1万DLG数据更新中采用"先内后外再内"的作业模式进行成图,对1∶1万DLG数据更新编制过程做了介绍,为今后工作的开展提供参考。
Based on the data of Digital Photogrammetric System and outdoor surveying,the indoors maps and updates 1∶10000DLG data.Meanwhile all kinds of elements and the relations between each other are correctly editted and expressed according to relative technical standards as well as specification requirements of the operation.The article discussed interacting operation mode between indoor operation and field operation.In addition,the text introduced the mapping and updating process of 1∶10000DLG data combined with production practice experience,hoping to provide some reference for the future work.
