Using Content Addressable aRchives to store decentralized data

When dealing with large geospatial datasets, such as Landsat 9 imagery, effective management, storage, and seamless transfer of massive data are key challenges for both data stewards and users seeking to access the content. One common solution for bundling and compressing these datasets is using .tar files (a type of File archiver), which aids data stewards in organizing into collections and simplifying data transfer for users. Transitioning into the realm of decentralized systems, Content Addressable Archives (CAR) present a solution akin to .tar files. CAR files, like their traditional counterparts, play a role in maintaining data organization and accessibility in decentralized setups. In this blog post, we’ll look into the technical details of CAR files and explore some practical advantages inherent to InterPlanetary File System (IPFS) and Web3.
