Abstract：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 1:50 000 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.
