Abstract: The process flow of building a spatial database is very vital to the general technical process of the digital geological survey system. According to the key technical problems such as the actual work amounts of geological workers, detailed solutions to these problems are proposed and realized as auxiliary tools of database building, data examination and data querying in the software systems of the digital geological survey system. Thus, it offers the technical guarantee for building the spatial database and ensuring the quality of data and also effectively improves the ability of application and efficiency of spatial database building.
