Project Showcase - Web3 Geospatial Dashboard
- 24 January 2024
What does user access to geospatial data look like in Web3? How can they find data or download content? Spoiler alert! Not much different than today but with the advantages of a decentralized network. One of the projects currently being fostered by The EASIER Data Initiative has been focused on user accessibility of decentralized content with a Web3 Geospatial Dashboard application and a Chrome extension. The dashboard is the entry point for a user to discover content, specifically Landsat 9 Collection 2 Level-1 imagery. With the Chrome extension enabled, a user is able to “pin” an image from our implementation of the SpatioTemporal Asset Catalogs (STAC) running alongside our IPFS node. Let’s dive into the details of our Web3 implementation.
Proof of concept for querying spatial data on IPFS using geohash
- 22 January 2024
In this post we’ll be exploring how to store and access geospatial data in a decentralized way using Geohash and InterPlanetary File System (IPFS). Geohash is a spatial indexing system that divides the Earth into a grid of squares and assigns a unique identifier to each square. IPFS is a peer-to-peer network that uses Content Identifiers (CIDs) to store and share data. By joining geohash to CIDs of spatial features , we can create a hierarchical indexing system that organizes geospatial features into a directory system based on the geohash encoding. This allows us to store and query geospatial data on IPFS, without relying on centralized servers or databases.
Proof of Concept Workflow Atomization Demo
- 01 July 2023
With a couple of use cases of code atomization now defined (shown in the previous post), this article will present a proof of concept for atomizing a simple Python workflow and generating a manifest of CIDs for the components used.
Decentralized and Deconstructed Approach to Code Artifacts
- 30 June 2023
For scientific publishing, being able to share artifacts such as data and code is imperative to illustrate a methodology in practice and support the validity of findings through replicability.
