Revolutionizing Farming with Decentralized Networks and Multi-Temporal Crop Classification Modeling
- 06 December 2024
Ever wondered how satellites help us understand what’s growing on our planet? In a world facing population growth, erratic weather, and food security challenges, crop classification has become a crucial tool for modern agriculture. Using satellite data to identify and track different types of crops, we can deliver critical analyses of global agriculture information. This post’ll dive into how NASA’s Harmonized Landsat and Sentinel-2 (HLS) data and the USDA’s Cropland Data Layer (CDL) are used in a multi-temporal crop classification pipeline. We’ll explore the use of decentralized networks such as IPFS and Filecoin and how they offer a more resilient and accessible approach to agricultural analysis and decision-making processes. Whether you’re new to crop classification or just curious about how these systems work together to forecast yields and inform agricultural decisions, this post will give you a perspective into the process and its potential impact on global food security.
GEDI - The Force Awakens in Open Science
- 28 October 2024
Measuring the impact of deforestation is one of the many overarching goals of the Global Ecosystem Dynamics Investigation (GEDI) project. With support of the GEDI’s LIDAR system and hitching a ride on the International Space Station, high-quality laser ranging observations collect a 3D structure of the Earths forests for which can be used to estimate the height of forests, the density of vegetation, and providing detail on the Earths carbon cycle. In this blog post, we will explore the GEDI dataset by leveraging IPFS with the ipfs-stac python library.
Workshop Executive Summary Now Live!

We’re excited to share the executive summary of our Workshop on Open Geospatial Science and the Decentralized Geospatial Web! This one-and-a-half-day event brought together over 30 experts from innovative organizations, federal agencies, and universities to explore how open science and decentralized web technologies can enhance the geospatial sector. This summary captures the key discussions and insights from the workshop, highlighting the potential to boost data accessibility, transparency, and collaboration. The full summary can be found here
Using Content Addressable aRchives to store decentralized data
- 25 January 2024
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.
