Abstract: Aiming at the problem that the data in the land surveying and mapping scene is difficult to trace and tamper with, a land data storage model based on the blockchain is proposed. The proposed model can realize the on-chain storage of land survey data and the association retrieval of on-chain and off-chain data. First, chain-uploading compression algorithm is designed for land surveying and mapping data. Then, a distributed digital fingerprint extraction method based on distributed slice storage and erasure code is proposed, and the extraction method is optimized concurrently to speed up the digital fingerprint extraction process and improve the chain-uploading efficiency. Finally, the on-chain and off-chain data association is introduced to further ensure data security. The simulation results show that the proposed model can save storage space effectively, prevent data tampering, achieve efficient upload of large-scale point cloud data, and improve data security and credibility.

Key words: blockchain, land surveying and mapping, data storage, storage model
