Open tutorial Run in VRE natif

Info

This tutorial can be run in CNES's VRE. First you need to follow this configuration steps. Then run the tutorial in the VRE.

Prerequisites

  • Basic usage of EODAG.
  • Basic knowledges of the Datalake (useful information can be found here)

Motivation

With the introduction of the Datalake object storage based on AWS S3 at CNES and Geodes, users of products distributed at CNES are faced with new interfaces for finding, viewing, retrieving or processing products from collections such as Sentinel 2. Users need a simple and efficient way of querying the Datalake or product catalogs to retrieve the paths to these products, often zipped, and access them using S3 protocol, which is much better than downloading them to a POSIX space such as the Trex cluster's tier 1 storage.
