Seen from space Exhibition [Océanopolis]




The exhibition SEEN FROM SPACE invites you to a unique journey in Brittany through exceptional images obtained by Earth observation satellites. These satellites are bearing sensors able to provide different kind of images from our planet. These snapshots reveal a reality that is difficult for the human eye to appreciate. The optical sensors capture moments similar to photographs, but allow us to see beyond the visible. Obtained by radar sensors, black and white prints reveal differences in texture on the surface of the globe. These particular sensors can acquire images through clouds, day and night. 

"The waves emitted, either naturally after illumination by the sun, or artificially after illumination by the radar sensors, contain information that is translated into images. Thus, these satellites produce different types of photographs thanks to the ability of the sensors to explore a large part of the electromagnetic spectrum, from microwaves to the ultraviolet."

René GARELLO, Professor at the Image and Information Processing Department at IMT Atlantique



Let's discover the invisible

These beautiful snapshots have a powerful visual impact, highlighting environmental and climatic phenomena, often invisible from Earth. They are also a rich source of data for the image processing industry.

The Brittany territory concentrates an important scientific expertise for the Earth observation from space (Universities, Engineering schools, Research institutes, industries, young companies). The Bretagne Télédétection (BreTel - Brittany Remote Sensing) cluster brings together all these partners to facilitate collaboration, enhance their skills and their work, and also help other players to take advantage of these space technologies.

In applied research or for operational applications, the themes explored are numerous and in fields as diverse as the detection of wetlands, the estimation of green spaces in cities, the development of habitat in rural areas or the properties of the ocean in coastal or offshore areas. These surfaces seen from space generate data that can be used to feed algorithms developed by research and development teams to monitor, for example, ships and oil pollution, but also physical phenomena (winds, waves, currents) and modifications due to climate change on continental surfaces (drought, fires, floods, crops, ...).

This exhibition was designed by Marie Jagaille for BreTel (Bretagne Télédétection), with the help of its partners (IMT Atlantique, University of Rennes 2, Ifremer, Ocean Data Lab, CLS), the European Space Agency (ESA), and was funded by the European project CoRdiNet (Copernicus), with the support of Nereus (Network of European Regions Using Space Technologies) and Océanopolis.
