基于区块链的新型基础测绘数据分发和共享模式

New fundamental surveying and mapping data distribution and sharing model based on blockchain

随着国家级新型基础测绘试点工作的开展和推进,具有各省市特色的新型基础测绘数据成果逐渐形成,安全可靠的数据分发和共享的组织管理模式也尤为重要。区块链技术自面世以来,在数据组织管理方面得到广泛应用。为此,本文以区块链技术为依托,构建了一套基于区块链的新型基础测绘数据分发和共享模式,以新型基础测绘数据生产、质检和应用三个环节为对象,阐述了基于区块链的数据分发与共享流程,并以Hyperledger Fabric技术搭建了基于区块链的新型基础测绘数据分发与共享原型系统,验证了该模式的可行性,为新型基础测绘数据成果安全共享和分发提供思路。

With the development and promotion of the state-level pilot work of new fundamental surveying and mapping,the results of new fundamental surveying and mapping data with the characteristics of various provinces and cities have gradually formed.The safe and reliable organization management mode of data distribution and sharing is also particularly important.Since its inception,blockchain technology has been widely employed in data organization and management.Therefore,based on blockchain technology,this paper constructed a set of new fundamental surveying and mapping data distribution and sharing modes based on blockchain.This paper expounded on the data distribution and sharing process based on the three links of new fundamental surveying and mapping data production,quality inspection,and application.With the support of Hyperledger Fabric technology,a new prototype system for the distribution and sharing of new fundamental surveying and mapping data based on blockchain was built,which verifies the feasibility of the model and provides a reference for the safe sharing and distribution of new fundamental surveying and mapping data.
