Application Feasibility Analysis of Block Chain Technology in Geospatial Data Sharing

Geospatial data sharing as a significant component of geoscience research. It is also an important means to exploit geoscience data and avoid repeated collection of geospatial data. It is an essential foundation for modern data-intensive geoscience research. Therefore, how to break the geospatial data “island” and realize different geoscience data portable access, secure data security, and promote geospatial data author copyright are urgent problems in geospatial data sharing. The rise of blockchain technology has brought new possibilities for the expansion of the value of geospatial data, the enhancement of data security and the improvement of the protection of the rights of stakeholders in geospatial data. Based on the systematic review of the status quo of data sharing, existing problems, basic principles of blockchain, underlying architecture, characteristics and application status, this paper discusses the application feasibility of blockchain technology in geospatial data sharing, and expounds the application challenges of blockchain technology in geospatial data sharing, in order to provide reference for the research and application of blockchain in geospatial data sharing.
