The invention belongs to the technical field of spatial information storage, and discloses a spatial data sharing system and method based on a distributed account book, and the spatial data sharing system based on the distributed account book comprises system function modules of a system application layer and a business layer and a data storage module of a data storage access layer. The system function module comprises an account information management module, a block chain network management module, a transaction record management module and a data quality management module. According to the invention, a block chain technology and spatial data sharing are combined, so that a distributed storage system integrating spatial data distribution, sharing and recording is realized; the authenticity and security of the spatial data sharing record are ensured by utilizing the characteristic that blockchain account book data cannot be tampered; and the transparency of data flow is increased by utilizing the characteristics of a distributed technology, the authenticity and security of data distribution, sharing and recording are realized, and the problems of single-point failure, data tampering and data traceability in the prior art are solved.
Description
technical field [0001] The invention belongs to the technical field of spatial information storage, and in particular relates to a distributed ledger-based spatial data sharing system and method. Background technique [0002] At present, the rise of the Internet industry has brought mankind into an unprecedented information age. The most valuable thing in the 21st century is not only technology, but also data. Human beings use ever-changing technologies to explore massive geospatial data related to ecological geography, earth science, and human life, and conduct multi-field and all-round analysis and processing of the acquired spatial data, so as to solve the current problems of resource utilization, environmental safety and natural disasters etc. Therefore, creating value by analyzing and processing spatial data has become a hot spot of current research. Spatial data often has a huge amount of data and complex data formats, which also makes spatial data ports in differen...
