Abstract

Aiming at the problems of incomplete audit mechanism and low degree of automation and intelligence in data sharing service of surveying and mapping results, this paper puts forward a method of compiling and sharing metadata of surveying and mapping results based on intelligent contract technology. Firstly, the metadata of surveying and mapping results is compiled, and the metadata system of surveying and mapping results oriented to smart contract is constructed. Then, according to different conditions of open data sharing, the intelligent sharing method of surveying and mapping results data based on metadata is designed. Finally, the metadata function of smart contract is expanded, and the right of sharing data based on metadata is realized. This method improves the automation and intelligence of resource sharing and exchange of surveying and mapping results catalogue, and lays a technical foundation for the realization of sharing and exchange system based on blockchain.
