Recent bugfix of MAJA v4, please consider upgrading to 4.5.4

A bug affecting the AOT estimates and leading to underestimated surface reflectances in some rare cases concerns all MAJA v4.x versions prior to 4.5.4. Users activating the CAMS option shouldn’t have noticed, but if you don’t use CAMS auxiliary data you may face this issue. Therefore, we highly recommend all users to upgrade to the […]

Les bassines de Boudnib

Alors que les bassines se développent en France pour stocker l’eau en particulier en Pays de la Loire, elles sont aussi utilisées au Maroc dans un environnement bien plus aride. Dans la région désertique entre Errachidia et Boudnib, près de la frontière algérienne, l’apparition de ces piscines géantes a transformé le paysage. L’eau est prélevée […]

Viedma glacier terminus since 1985

Viedma Glacier is an iconic glacier of the Southern Patagonia icefield. Landsat 5, Landsat 8 and Sentinel-2 images series show that its terminus has retreated by 3 km since 1985. Looking closer one can notice a new proglacial lake forming in a recently deglaciated area. Since I won 80 sq km of Airbus Pléiades data, […]

First validation results with the Lamasquère ROSAS instrument

=> Following its installation in March 2021, our new ROSAS device at Lamasquère has produced a first series of acquisitions over a complete maize crop cycle. The ROSAS system is based on the use of a multi-spectral photometer to carry out angular and spectral measurements of both incident and reflected radiation from the surface. The […]

The snow you can’t see

Last year in November we noticed these unusual white spots in a Sentinel-2 image near Barèges… These white spots were artificial snow spread by snow cannons. At the same time of the Sentinel-2 acquisition, they were also « visible » as cold spots from our thermal infrared camera installed at Pic du Midi. This year in November […]
