Join our Webinar on 14 February 2023

The H2020 Global Earth Monitoring (GEM) project, whose aim is addressing the challenge of continuous monitoring of large areas in a sustainable cost-effective way, is entering in its last phase. This event aspires to gather different actors from the Earth Observation domain and beyond to show the results of the project (with a particular focus on the outcome of its use cases).

The event is remote and free. Please feel free to register for both sessions separately via the links below and join us on 14 February 2023 at 10:00 CET.

Morning Session: Projects outcome and user feedback

The EC Project Officer and the Project Coordinator will provide an overview of GEM and its position in the EO R & I scenario. Successively, the project partners will resume the pilot outcomes and the audience will be able to provide feedback through interactive polls on the proposed solutions; the feedback will be considered by the consortium in the definition of the way forward.

Afternoon Session: Hands-on GEM

The step-by-step exercises will feature the use of GEM resources. The exercises, for which preparatory material and requirements will be circulated in advance, are targeting students, Software developers, Data scientists, EO-developers, and anyone with an interest in the topic.

REGISTER for the afternoon session

The afternoon session will be dedicated to guided exercises to show GEM outcomes and to exploit the developed tools by the different partners (approximately 45 minutes each session).

13:30 – 17:30   Guided exercises (GEM consortium)


How do we apply EO workflows to larger scale? Working with EO data is made easy by the eo-learn package, while the eo-grow package takes care of running the solutions at a large scale. In this session we will have a look at the GEM processing framework:

  • First, we show how we have used eo-grow to create two static data cubes, Sentinel-2 data and aggregated weather data, both with monthly cadence at 120 m resolution.
  • Next, we will guide the audience through a slimmed-down EO workflow using a Jupyter notebook and eo-grow, which is small enough to be run on a laptop. You will learn about the main eo-grow structural blocks (pipelines, managers, configuration schemas), that drive the execution and allow for the reproducibility of the runs. The example will show the typical EO pipeline, from data retrieval, predictions with preexisting model on the features, and finally to uploading results as data cubes on Sentinel Hub.


  • Weather data access examples
    Learn how to load a large variety of weather data for your geography and period of choice, at the spatial and temporal resolutions and aggregations that you need. A high performance API gives rapid access to top quality data with minimal effort. An interactive configurator allows you to compose your query, preview results, and generate the appropriate API call(s).
  • Walk-through of creating urban heat maps
    Learn how to extract the structure of a city's temperature field from satellite data. Combine it with weather data to generate an urban heat island map.


  • HowTo use GEM ML framework
    Learn how to use the GEM ML Framework for synergetic interaction of PyTorch and eo-learn for ML in EO at scale. We will have a look at a segmentation pipeline for the detection of deforested areas. In the process, you will learn how to properly normalize your larger-than-memory datasets, how to feed them to your model of choice and how our generic pipelines can be used (for your own research). In the end, you will be able to integrate your trained models into eo-learn workflows for inference pipelines.
    Please note that you need a running version of Python, a CUDA-enabled device and a good understanding of programming to fully enjoy the experience.


  • During the demo session, different datasets of interest for understanding climate security issues will be explored.
    The demo session will be executed in Binder, using Python and Jupyter notebooks. There is no need of previous software or library installation, basic knowledge of Python would be desirable.

    • Exercise 1 will focus on the visualization and analysis of socio economic data of relevance for climate security in the Sahel region. The exercise will use open data from World Bank (e.g. GDP, Unemployment rate, mortality, birth rate, …).

    • Exercise 2 will focus on the visualization and analysis of soil moisture levels in Nigeria, specifically in the northwest region of the country that was affected by floods in 2019. The exercise will use Sentinel-2 data provided by Sinergise via Sentinel-Hub and meteo data provided by meteoblue.


  • LC-CMS prototype on Jupiter notebook
    In this hands-on session, attendees will have the opportunity to work with a prototype/lightweight version of the LC-CMS pipeline. The session will provide a firsthand experience of Continuous Monitoring and Change Detection of LC classes through the LC-CMS pipeline.
