摘要
地质图是基础地质工作成果展示的核心载体,但不同时期完成的地质成果图件编制标准不统一,同时还存在相邻图幅接边等问题,难以及时更新升级,给使用者带来诸多不便。为此,安徽省采用了统一地层划分、图面表达及标注,对本省1∶5万比例尺区域地质调查成果进行了数字化系统整理修编。提出了“尊重原著、遵循规范、不漏信息、表达统一、清晰易读、美观和谐”的修编原则,分析了修编过程中常见的问题,创建了“数字化→整理校验与问题处理→说明书更新”的修编流程,解决了地质图修编过程中缺少行业规范指导的难题。修编后的地质图得到了升级,集成了最新地质成果,消除了错漏,实现了规范统一且美观易读,提升了“地质云”基础地质数据共享平台的服务能力,满足了成果资料系统化管理、使用、共享的需求。
Geological map is the core carrier of the display of basic geological work.However,the compilation standards for geological maps in different periods are not uniform,and there are also problems of adjacent sheets junction.Thus it is necessary to update these maps,which otherwise will bring considerable inconvenience for users.In order to solve these problems,unified stratigraphic classification,expression and marks were adopted during the process of systematically revising the 1∶50000 regional geological survey maps in Anhui Province.The revision principles were put forward as‘respecting the original work,following the norms,not leaking information,unitary expressing,reading clearly and easily,revising beautifully and harmoniously’.The common problems in the process of revision were analyzed,and the revision process was created as‘digitization→verification and problem processing→explanatory notes update’,which solved the problems of lacking detailed process guidance during the geological map revision.The geological map has been upgraded after revision,and the latest geological achievements have been integrated without mistakes and omissions,which makes these maps unitary and easy reading.The revised maps improved the service capacity of the“geological cloud”basic geological data sharing platform,and meet the needs of systematical managing,using and sharing of results data.
