The Remote sensing Environment, Analysis and Climate Technologies


The Remote sensing Environment, Analysis and Climate Technologies Technical Committee (REACT TC) is a venue for all scientists and engineers in the domain of environment and the impact on the environment due to climate change forcing in order to exchange ideas and share knowledge. It aims at advancing science, defining requirements for science driven mission concepts and data products in the domain of Cryosphere, Biosphere, Hydrosphere, Atmosphere and Geosphere.

Near Real-Time Monitoring of Flood Inundation in Africa using Remote Sensing and Machine Learning

In recent years, there has been an uptick in the frequency of climate disasters across the globe. African countries are generally poorly equipped to recover and adapt to climate-related shocks, most notably, disastrous flooding. According to Africa’s Pulse publication (Zeufack et al., 2021), within the last decade, storms have quadrupled in frequency while floods have also increased tenfold when compared to the 1970s. Since 2015, Cloud to Street has supported humanitarian organizations and governments of 28 countries across Africa with a near real-time multi-sensor flood monitoring system. In this talk, this system, utilizing Landsat and Sentinel constellations coupled with our deep learning based CNN flood detection algorithm, will be demonstrated. We will also show how this flood monitoring system provides the necessary historical data to assess and mitigate risk, improves situational awareness, and informs disaster response and recovery with medium to high resolution satellite observations.

2022 EO4SDG Contest Winners

The Technical Committee REACT of the IEEE Geoscience and Remote Sensing Society are proud to announce the winners of our 2022 EO4SDG contest.


New REACT (EO4SDG) Competition

The mini projects for Sustainable Development Goals competition is an initiative of the IEEE Geoscience and Remote Sensing Societies Technical Committee REACT (Remote sensing Environment, Analysis and Climate Technologies) to support science and to motivate local students to work together on a specific topic related to Earth Observation and Sustainable Development Goals (EO4SDG).

“Earth at Risk” Photo Contest

The IEEE GRSS Young Professionals and REACT Technical Committee (Remote sensing Environment, Analysis and Climate Technologies) are pleased to announce the photo contest “Earth at Risk” organized in conjunction with the mini-projects for sustainable development goals competition.

The next webinar in the Sustainability series is on December 7th at 12 Noon EST on using remote sensing to detect Methane emissions. Sign up here.

An invited session is planned for IGARSS 2022 in Kuala Lumpur, Malaysia taking place 17-22 July, 2022. The session is open to all that like to share their recent results on remote sensing towards sustainable development goals and is entitled as ‘Advances in remote sensing towards sustainable development goals’.

The technical committee will meet at IGARSS 2022. We will organize a hybrid (in presence and online) discussion session on what can be done more in remote sensing to advance and to reach the sustainable development goals.


The REACT TC is open for a wide range of people with different expertise and background and working in different application areas. We are happy if you provide feedback, suggestions, or ideas for future activities.

You can engage with us by contacting the Committee Chairs by email, join the LinkedIn IEEE GRSS Forum, or join the REACT TC!
