Tutorial to learn how to access and process Satellite Data using Python and JupyterLab in the Cloud
This tutorial aims to provide scientists who want to use satellite data with the necessary tools for obtaining, temporally analyzing, and visualizing these data using the Cloud. Note: This in not a tutorial on Python per se - there are a myriad of resources for that. The purpose of this tutorial is to learn, through examples, only the necessary Python code and tools required to do simple temperal analysis of satellite data. We want you to get your toes wet, get to see and use the power of Python, and then maybe you will want to learn more. For that, we encourage you to visit the links on the Resources section at the end of each chapter.
This project, supported by the Better Scientific Software foundation, and originally by NASA, aims to increase accessibility of satellite data and cloud technologies to a broad scientific community through easy-to-follow Python examples.
This tutorial is developed to run and access satellite data on the Cloud. (For this release, data used are local or available online, and the second release will include Cloud data access).
To launch the tutorial:
- Click on the binder icon below. It will redirect you to an online version of the tutorial.
- It might take some time to load the first time, but eventually you'll be promted with a Jupyter environment, listing the Chapters of this tutorial, on your web browser (See Chapter 2 for a brief guide on Jupyter Notebook).
- Double click on the Chapter you want to work on. It will open in a new tab.
- At the end of the session, quit the session (top right of the page).
- You can access the tutorial (repeating this same procedure) as many times as you want.
This tutorial is divided into Chapters that provide the necessary tools as building blocks. These chapters are stand-alone, so can be skipped if you are familiar with the particular tool presented.
