Abstract：The construction of the 1:50 000 Regional Geological Map Spatial Database of Northeast China lasted 16 years from 1999 to 2015. The database collects a great deal of basic geological information obtained from the 1:50 000 regional geological survey in Northeast China since 1960s. With the database construction, the complete level of regional geological survey and the status of information were checked and ascertained. The spatial database includes 382 sheets of 1:50 000 regional geological maps by traditional mapping. A perfect quality control system was established to improve the acceptance method and process of spatial data and normalize the basic grading method and achievement evaluation.
