Results of the 1:50000 regional geological surveys are high-degree processed geological information. This basic and public geological information have made a profound influence on the economic and social developments of China. The construction of the 1∶50 000 regional geological map databases began in 2000. Until 2014, 116 standard sheets of early paper geological maps had been vectorized and imported into database. The construction of the regional geological map database generally includes images vectorization and attributes valuation, and the geological attributes are the core of the database. The key to the construction of the regional geological map database is the geological data acquisition and processing. This paper discussed the preprocessing of geological data and the division of geological map, as well as mainly analyzed certain problems within the geological data acquisition and processing.
