Le pôle toulousain de recherche publique en télédétection est surtout connu sur la thématique forestière grâce à la mission BIOMASS, qui sera lancée vers 2021 et qui est portée par le CESBio, mais qui concerne surtout les forêts tropicales. L’objectif de cet article est de présenter les travaux en cours sur les forêts tempérées, dans […]
This is a time-lapse of all clear-sky images captured by Venµs over the Khumbu Icefall near Mount Everest since November 2017 (one year of data, 51 images at 5 m resolution) . Here I used the Level-1C products (i.e. without atmospheric correction) because the Level-2A products are provided at a lower resolution (10 m). Anyway, […]
You might have noticed the apparition of the first Venµs L2A products on Theia web site within the real time production, since last Friday. A first global processing will start this summer, to provide you with the data acquired from November until now. There will be probably further reprocessings to benefit from the fine tuning […]
Summary Until V0.9, only a small proportion of Venµs L1C data were available at L1C level on Theia’s website. Now, with the version V1.0, a greater proportion of products will be distributed to users, but we advise users to check their geometric quality in the metadata, as explained below. Distribution of V1.0 products should […]
Theia just published the first Venµs images today, including a beautiful view of the Pyrenees. Once you have dezipped/untared/unzipped the files you can make a true color composite using the command:gdal_translate -b 7 -b 4 -b 3 -scale 0 300 0 255 -ot byte VE_VM01_VSC_PDTIMG_L1VALD_ES_LTERA_20180419.DBL.TIF myColorCompo.tifI tend to focus on the snow so I stretched […]
Great news for our little Venµs satellite project: Theia has started distributing Venµs L1C data in near real time. The data acquired yesterday are already available on https://theia.cnes.fr These L1C products are tagged with 0.9 version, which means that their quality is not as good as what we think we will be able to deliver in […]
A first set of 35 images (L1C) is available for download on the following CNES web site: https://theia.cnes.fr Venµs is now systematically acquiring data on all selected sites since January 2018, although a few acquisitions were missed from time to time for various technical reasons, which should become progressively less frequent. The commissioning phase of the […]
Hereafter some news on the status of the Venµs mission.Venµs was successfully launched from the Kourou space port on August 1st by a VEGA launcher: https://vega.cnes.fr/en/live-vega-launch-venus-august-first-2017 First images were acquired by mid-August (see below for examples). The commissioning phase is still running. This phase consists in checking the whole system, including the satellite, the camera, the download […]
Le satellite Franco-Israelien Venµs, attendu depuis si longtemps, a été lancé le 2 août 2017. 110 sites dans le monde vont être observés en 2018 et 2019 à 10 m de résolution et avec 12 bandes spectrales. Alors que la plupart des sites ne correspondent qu’à l’emprise d’une scène Venµs (27 à 32 km de […]
