Mapping Our Planet in High Resolution: Advancing Land Cover and Degradation Monitoring with Sentinel Data

Details

Effective monitoring of global land cover is crucial for addressing challenges such as land degradation, sustainable development, and biodiversity conservation. The availability of Copernicus Sentinel-1 and Sentinel-2 satellite data has revolutionized the field of land cover monitoring, enabling high-resolution observations at unprecedented scales. These advanced Earth Observation (EO) technologies now facilitate detailed analysis of land use and land cover changes, providing insights into the dynamics of terrestrial ecosystems.

This webinar explores how these innovations, coupled with emerging datasets and services, are being utilized to monitor global land cover and land degradation, supporting sustainable development and environmental conservation. Specifically, the webinar will delve into experiences of producing the 100m Copernicus Global Land Cover dataset (available for 2015–2019), the European Space Agency (ESA) WorldCover Project, which has further advanced land cover monitoring by producing 10m resolution global land cover maps, and the new Copernicus Land Cover and Tropical Forest Monitoring Service (LCFM), designed to provide dynamic, high-resolution datasets on the status and changes of global land cover and pan-tropical forests.

Another focal point of this webinar is the ESA Sentinel for Land Degradation Neutrality (SEN4LDN) Project, which has developed, demonstrated, and validated robust and automated EO methods to map land cover changes and land productivity dynamics at high spatial resolution. This project plays a critical role in addressing the demand for high resolution datasets to enable countries to monitor progress on Sustainable Development Goal (SDG) Target 15.3, which aims to achieve land degradation neutrality.

The webinar highlights how these projects collectively address the pressing need for robust, scalable, and accessible tools for global land monitoring. By combining advanced EO technologies, such as Sentinel satellites, with open data principles, these initiatives empower a broad range of users, from policymakers to researchers and local communities. Participants will gain valuable insights into the synergies between these projects and their cumulative contributions to global environmental monitoring, land restoration efforts, and sustainable development goals.

The duration of the webinar is 1,5 hours: 1 hour presentation followed by 30 minutes Q&A. During the webinar there is a live chat available.

The webinar will be executed under the framework of the EO AFRICA R&D Facility by VITO Remote Sensing.

Advances in EO Cloud Computing: OpenEO

Details

This webinar explores the growing role of cloud computing in analyzing and processing Earth Observation (EO) data, with a primary focus on OpenEO. OpenEO is a relatively new and innovative initiative to connect to EO cloud back-ends in a simple and unified way. The project maintains the API and process specifications, and an open-source ecosystem with clients and server implementations. Participants will learn about the design and inner workings of the system, as well as existing capabilities and recent advancements of OpenEO. The session will cover interactive computing using the OpenEO web interface and JupyterLab, where attendees will be guided through a hands-on demonstration of a simple analysis workflow implemented on openEO. This practical demonstration will help participants understand the relative capabilities, flexibility, and application areas of openEO.

The webinar aims to equip participants with the knowledge to:

  • Understand the key features and latest developments of openEO.
  • Gain hands-on experience in implementing a simple workflow on openEO by using the web interface and Python.
  • Recognize the strengths and limitations of openEO.
  • Get an introduction to interactive analytical processes, demonstrated through Jupyter Notebooks.

The duration of the webinar is 1 hour, followed by a 30-minute live Q&A session. A live chat will be available throughout the webinar.

The webinar is organized under the framework of the EO AFRICA R&D Facility by the Faculty of Geo-information Science and Earth Observation (ITC) of the University of Twente.

Flood extent assessment in East Africa with Sentinel-2 data

Details

A few months ago, East Africa faced the consequences of weeks of heavy rains and subsequent flooding, attributed in part to the El Niño weather phenomenon, impacting Kenya, Tanzania, Uganda, Rwanda, Burundi, and Somalia. According to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), the flooding has devastated communities, with over 750,000 people affected and 234,000 displaced across the region. Tragically, the death toll continues to rise, with at least 400 fatalities including over 155 deaths in Tanzania and 257 in Kenya, as per local authorities. Flooding in the area resulted in tens of thousands of individuals requiring necessities such as food, shelter, clean water, and healthcare, and thousands of hectares of crops damaged.

Satellite sensors, play a pivotal role in flood monitoring not only to assess hazards but also to support in early warning, mitigation and protection of lives and properties. The European Commission initiated the Copernicus program a few years ago, introducing a novel series of Earth Observation satellites called the Sentinels. In this webinar we’ll utilize commonly used methods to assess the extent of selected flooded area in East Africa. Presented techniques will include calculation of water radiometric indices from optical Sentinel-2 bands (e.g. MNDWI, NDWI2, SWM) to assess the water extent and change detection in selected area. Practical demonstration using open-access software will guide attendees through basic processing steps to achieve desired results.

The duration of the webinar is 1 hour, followed by a live Q&A session. During the webinar there is a live-chat available as well.

The webinar will be executed under the framework of the EO AFRICA R&D Facility by SERCO Italy S.P.A.

Accessing cloud services using openEO and additional data processing capabilities offered by ILWISPy

Details

The EO Africa program has been making use of the Innovation Lab as backbone facility for cloud based access to remote sensing data and subsequent data processing. This webinar starts with the use of the Innovation Lab in conjunction with openEO / ILWISPy to access and process also data obtained from other cloud based data repositories.

Attention will be given to relevant cloud based data repositories which can be used to derive a multitude of datasets, like access to the Sentinel suite of satellite images, other relevant archives through API access, like FAO WaPOR, Copernicus Climate Data Store, Royal Netherlands Meteorological Institute and EUMETSAT’s EUMETView. Last but not least some of the capabilities currently offered by WEkEO will be provided.

After a short introduction on openEO and ILWISPy capabilities developed, the webinar is of a highly demonstrative nature using Jupyter Notebooks showing how to access and process the data from the above mentioned cloud based services.

The duration of the webinar is 1 hour, followed by a live Q&A session. During the webinar there is a live-chat available as well.

The webinar will be executed under the framework of the EO AFRICA R&D Facility by ITC-UTwente.
