iota2 is the large scale mapping software developed at CESBIO. iota2 takes high resolution satellite image time series (SITS), usually Sentinel (1 and 2) or Landsat, and produces maps over large areas. Maps of most usual variables of interest in remote sensing can be produced, since iota2 can compute user-defined functions at the pixel level, […]
B-22A is the largest iceberg in the Amundsen Sea, Antarctica (50 times Manhattan land area). It broke off from Thwaites Glacier’s tongue and remained grounded for 20 years.. But now it’s on the go, as shown by this animation I made from Sentinel-1 SAR images (about 1 per month since June 2015, total 75 frames): […]
In this article, ESA gave us some news of the time table for the coming launches of next Sentinel1 and 2 satellites. As you may have heard, we have these days a shortage of European launchers, due to the ending of Soyouz launches from Kourou, the delays in Ariane 6 delivery, and the initial uncertainties […]
=> Claire Pascal, PhD student at CESBIO, under the supervision of Olivier Merlin (CNRS researcher) and Sylvain Ferrant (IRD researcher) brilliantly defended her thesis on the monitoring of water resources by satellite on November 18. Claire’s work focused on the Telangana region of India where rainfed cotton and flooded rice farming dominate. The region has […]
The VENµS satellite was launched in August 2017, with two missions : As a result, VENµS has had different phases separated by orbital changes. It’s imaging phases are VM1 at 720 km altitude, which lasted for three years, and the current VM5 phase at 560 km altitude, which started in March 2022. So, what will […]
Due to Brexit, the ECMWF moved some of its computer infrastructure from Reading (UK) to Bologna (IT), and a 5 week interruption of service occurred for the production of Copernicus Atmosphere Monitoring Service. As our Level 2A production for Sentinel-2 uses this information to set the type or aerosols for the atmospheric correction, we had […]
Here are some long awaited news about the VENµS VM5 phase. The acquisitions started end of March 2022 with the following list of sites, and should go on for at least one year, and maybe more depending on the consumption of fuel (Hydrazine) to maintain the orbit. Most of the sites are acquired with a […]
I found the leak from Nord Stream 2 in the latest Sentinel-1 image (29 Sep 2022). It’s large enough to be visible from space. From this radar image, I could also spot the leak in the Landsat image captured on the same day (29 Sep). And there’s another leak visible northeast of Bornholm Island, this […]
We are hiring an expert (M/F) in scientific computing to improve the consideration of aerosol type in the MAJA Earth observation image processing chain using machine learning methods. The aim is to explore single and multi-variable regression approaches in order to select the most efficient one, which is the result of a trade-off between simplicity […]
