摘要
进行过大量 1∶5万区调填图、研究程度较高地区的 1∶25万区域地质调查,其核心任务是充分挖掘利用前人资料及二次开发,在广西 1∶25万玉林市幅PRB数字填图试点过程中,经过两年多来的摸索研究,初步总结出一套前人剖面资料录入、验证、批注、修测和成图过程的工作方法,已基本上达到了在 1∶25万区调修测区推广应用的“实战性”要求。
The key task for 1∶250000 regional geological survey in the areas with most of 1∶50000 regional geological survey and high degree of research finished is to effectively utilize the former geological data. During the experimental stage for two years in PRB Digital Geological Mapping of 1∶250000 Yulin Sheet in Guangxi,the authors summarized a set of work method for data input,validation,commentary ,resurvey and plotting of the former section data, and the method has significance of extending application.
