Cloud Native Geospatial for Earth Observation Workshop

This repository contains workshop materials to that introduce cloud native methods of working with Earth observation data products.

The repository focusses on the use case of measuring land productivity as a subindicator of Sustainable Development Goal indicator 15.3.1: Proportion of land that is degraded over total land area. For more infromation please see the Satellite Data Requirements for SDGIndicator 15.3.1 document.

The selected application area is a forested region in Capão Bonito, a municipality in the state of São Paulo in Brazil.

Quickstart

Tutorial PDF

Along with a completed notebook, we provide a step-by-step PDF document. This was used to run the tutorial at SatSummit 2024.

Start the Codespace

The easiest way to get started running through this workshop is to launch a GitHub Codespace, which includes a VS Code web environment that includes the ability to run and edit Jupyter Notebooks.

1. Click the green Code button
2. Click the Codespaces tab
3. Click Create codespace on main

Sign into NASA's Earthdata portal and create an access token

Sign up for EarthData: https://urs.earthdata.nasa.gov/

1. Log in or create an account on EarthData
2. Go to the Generate Token tab
3. Click the green generate token button
4. Copy the token to your clipboard

Add the access token to secrets.json

In the Codespace:

1. Rename secrets.json.sample to secrets.json
2. Paste your token inside the quotation marks

{
   "earthdata": {
       "token": "TOKEN_GOES_HERE"
   }
}

Run the demonstration notebook

Open the Cloud_Native_Land_Productivity_For_SDG15.ipynb notebook and work through the cells.

Authorship and sponsorship

This notebook was written by Alex Leith and Caitlin Adams, with financial support from the Committee on Earth Observation Satellites and advice from members of the GEO Land Degradation Neutrality Flagship.
