Voilà ! The new version (V2.0) of SPOT4-Take5 data set is available, for the 45 sites. I would like to thank the development and processing teams of MUSCATE center in CNES, who work for THEIA, the image quality teams at CNES (SI/QI and SI/MO), and of course Mireille Huc at CESBIO, for the production of this new version, which finally required a lot of work.The product version number is not included in the filenames, but you can recognise a V2.0 product by looking into the xml metadata file :

<METADATA>  <HEADER>    <VERSION>2.0</VERSION>

This reprocessing brings the following new features :

• We provide quicklooks on which you can see the cloud and shadows masks
• We enhanced the quality of the ortho-rectification :
• By changing the référence ortho-image for the sites in France (GEOSUD, processing done by the french institute for geography IGN)
• by replacing the LANDSAT 5 otho-images by LANDSAT 8 images for most other sites outside France. LANDSAT 8 geometric performances are enhanced compared to  LANDSAT 5.
• however, for a few sites (Borneo, Gabon, Congo (1,CNES), CCRS, Cameroun), no clear LANDSAT 8 images was available yet and we had to keep the LANDSAT 5 reference.
• It’s not too bad for Congo, CCRS et Cameroon, as LANDSAT 5 references where quite good, for Gabon, we used a reference made with the cloud free image obtained with SPOT4-Take5, and finally, we just have Borneo site for which the level 1C obtained are quite bad with large registration errors (I am sorry Jukka)
• A large enhancement of the performances has been observed for Sumatra, Gabon and Congo (2,ESA), for which the first version was quite bad.
