Abstract: Geological data double track system is a document management mode that is recognized in China's geological data field and widely used by practice departments.With the development of science and technology, the double track system of geological data has the disadvantages of waste of resources, increased workload and cost, high resource occupation and limitations, and it cannot exist forever.After the technical and institutional conditions are mature, the double-track system of geological data will inevitably transition to the electronic document monorail system.Based on the work of geological data business, this paper analyzes the shortcomings of the current double track system, discusses its prospects for the transition to the monorail system of electronic documents, and proposes targeted measures and recommendations.
