NDVI on Landsat 9 imagery with data using IPFS

Geospatial professionals frequently handle vast data sets, like satellite imagery, for tasks ranging from object detection to land cover classification. The Normalized Difference Vegetation Index (NDVI) is a widely-used metric for assessing vegetation health in a given area. In this blog post, we’ll walk you through calculating NDVI using Landsat 9 imagery and the IPFS network with the help of the Python library, ipfs-stac, in a Jupyter notebook. We’ll also discuss the benefits of leveraging IPFS in geospatial workflows, such as content-addressing and decentralization.

Seamlessly Fetching Files from IPFS - A Proof of Concept for Building a Flexible Local Client

As decentralized web technology continues to develop, the InterPlanetary File System (IPFS) offers an alternative approach to distributed file storage and sharing. In this notebook, we will present a proof of concept for building a flexible local client capable of fetching files from IPFS, regardless of whether the user has a local IPFS node or not. We will also discuss the advantages of using a local IPFS node over relying on public gateways, and showcase how to implement a fallback mechanism for maintaining uninterrupted access to IPFS content.
