Do you know the CNES/AIRBUS CO3D mission ? As our Sentinel-HR mission could be made of satellites derived from those of the CO3D mission, it is a good opportunity to advertise this nice mission here. I took all the information from a presentation and a paper [1] written by Laurent Lebègue and the CO3D […]
There are several MAGicians in the CESBIO laboratory, and I am one of them (with all due modesty). According to my definition, MAGicians are participants to Mission Advisory Groups, for instance for CNES or ESA satellite projects. These days, I participate to the MAG for Sentinel-HR at CNES, and for Sentinel-2 Next Generation at ESA. […]
This post intends to answer a question about Sentinel-HR, that we have had quite often inside or outside CNES : Securing continuity in a critical timeseries requires user community foresight, Programme justification, 10 yrs Agency prep, and finances. Whilst Sentinel-HR may well be an excellent/valid idea, I’m left asking why certain Copernicus contributing missions couldn’t […]
In the previous post, Olivier advocated for the open data policy in remote sensing. Although Oliver is facing some actual resistance because the Sentinel-HR mission would step on the toes of industrial champions, my feeling is that there is now a large consensus on this issue. The economic and social benefit of the open data […]
As for most users of Copernicus or LANDSAT data I guess, the advantages of free and open remote sensing data are so clear that it’s hard to imagine they could be challenged. However, in the framework of Sentinel-HR phase 0, we prepared arguments in case our requirement for free and open data is questioned. Table […]
=> In 2018, Olivier Hagolle presented in this article the Sentinel-HR concept : an optical satellite in the metric spatial resolution class providing global, repetitive, systematic observations with an open access policy. By doing so, he continued the work of Gérard Dedieu who had already advocated for this concept in the previous years. Thanks to […]
=> En 2018, Olivier Hagolle vous avait parlé dans cet article du concept Sentinel-HR : une mission de résolution métrique fournissant des observations globales, répétitives, systématiques et libres d’accès. Il reprenait ainsi le flambeau de Gérard Dedieu qui portait déjà ce concept dans les années précédentes. Fruit de ces années de sensibilisation, une étude de […]
A single VENµS acquisition is sufficient to estimate the terrain elevation of a scene thanks to the so-called « native stereo » technique. One of the main missions of VENµS, the Franco-Israeli satellite launched in August 2017, is to carry out acquisitions over more than a hundred scientific sites around the world. Its resolution at 5.3 m […]
Une seule acquisition VENµS suffit pour estimer le relief de la scène grâce à la technique dite de « stéréo native ». Une des missions principales de VENµS, le satellite franco-israélien lancé en août 2017, est d’acquérir régulièrement des images sur plus d’une centaine de sites scientifiques répartis dans le monde. Sa résolution à 5,3 m par […]
