swisstopo colloquium: From satellite pixels to forest stress

On December 5, 10:00–11:30, swisstopo will host¹ a colloquium focusing on a use case for high-resolution satellite data. The topic is “From Satellite Pixels to Forest Stress: swissEO Products for Real-time Environmental Monitoring”.

The colloquium will offer a look at an operational EO product pipeline with the following characteristics:

• Products: Focus on swissEO S2-SR (Sentinel-2 Surface Reflectance²) and swissEO VHI³.
• Backend: The backend uses Google Earth Engine, Github Actions, and open-source software.
• Delivery: Cloud-native formats served via a STAC interface⁴.
• Application: A collaboration between swisstopo, MeteoSwiss, and the Federal Office for the Environment (FOEN), the derived data is used in platforms like waldmonitoring.ch and TreeNet.
