SPOT4 (Take5) / Progress report

In English SPOT4 (Take 5) THEIA

Olivier Hagolle, 16 février 2013

=> SPOT4(Take5) experiment started two weeks ago, here is a progress report :

  • Image acquisitions are progressing nominally, but the weather above France is very poor. Other sites are much better off.
  • Production of Level 1A images started at SpotImage. It is done once a week, on Thursdays. Accounting for the delay before image download, up to 2 weeks may happen between an image acquisition and level 1A product delivery.
  • First ortho-images have been generated, and the fusion of 4 SPOT4 images works fine and almost seamlessly.
  • As soon as we get our first time series above a given site, we will start testing and tuning the Level 2A methods (Cloud detection, atmospheric corrections)
  • The MUSCATE processing centre of the French Land Thematic Centre started its adaptation to SPOT4. Modifications will take a few weeks, and after that we will be able to start operational production.

The missing link to valorize CESBIO’s applicative research works

=>  My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]

Sentinel-2 overtakes Landsat in scientific litterature

OpenAlex is a new, yet already very useful, open database for exploring scientific literature. For an upcoming blog post on the CNES Datacampus website, I analysed the proportion of papers that used only one of the Sentinel-2 or Landsat missions, as well as those that used both, in 2025. What struck me was that Sentinel-2 […]
