Exploration on the long-term preservation technology of geological data under the background of big data

The rapid development of information technology has enabled more geological surveys to complete geological surveys by means of information technology, thus forming geological data with large data volume, multiple data types, high data reuse rate and high potential data value.Carry out research on long-term preservation technology of geological data electronic data, and provide a set of long-term safe, credible and usable continuous maintenance mechanism for geological survey results data, so that the geological survey results data can provide more and deeper basic data for national economic construction.support.This paper explores and considers the long-term preservation technology of geological data electronic data, analyzes the current status of preservation of electronic data of geological data, and explores and studies the long-term preservation of electronic data in the context of big data era.It provides the necessary theoretical basis for the safe preservation and sustainable use of geological data electronic data, and promotes and promotes the comprehensive information transformation of geological data management.
