Production of LANDSAT L2A data at THEIA to begin shortly.

=> At CNES, the prototype MUSCATE production facility of THEIA land data centre will soon start the production and distribution of Level 2A Landsat 5 and 7 data, and shortly after of LANDSAT 8 data covering the entire surface of France.   For Landsat 5 and 7, we use data from both USGS and ESA : […]

A python module for batch downloads of LANDSAT data.

=> The Python routine, provided via the link at the end of this post, enables batch downloads of LANDSAT data, on USGS earth explorer site. It works for LANDSAT 8 and LANDSAT 7 (and could work for LANDSAT 5), it just requires that the data are available on line. It is the case for all LANDSAT […]

A new year of time series

=> Dear readers of this blog, all my best wishes for 2014 !  May this new year bring you nice image time series, but spare you some time to process those recorded last year (among which SPOT4 (Take5) ;)). Even if 2014 will be another year without Sentinel-2 and VENµS, let’s guess that with LANDSAT-8 […]

Venµs launch contract just signed

=> We could have written a real cliffhanger serial on this blog, describing the list of rockets that were someday supposed to launch the Venµs satellite : the first one was Dnepr (an Ukrainian rocket derived from intercontinental missiles) at the time the project was decided, a long time ago, then the PSLV Indian launcher […]

New satellites added to SMAC atmospheric correction

=> New coefficients have been added to the CESBIO repository for SMAC coefficients. The new sensors taken into account are :  The Simplified Model for Atmospheric Correction (SMAC) is the perfect model to perform easy, quick and not too dirty atmospheric corrections. It is based on very simple analytic formulas, based on the 5S model. […]

What about playing Take Five again with SPOT-5 ?

=> This post is regularly updated with news (the official date of Sentinel-2 launch) or to add new arguments. SPOT5 will soon end its career. After 12 years of image acquisitions, the satellite will retire in 2015. CNES might launch a call for scientific experiments with SPOT5 before the satellite de-orbitation. I am quite sure […]

Using High Spatial Resolution Time Series to monitor forage production

=> An index-based insurance solution is developed to estimate and monitor the near real-time forage production in France. In this system, payouts are indexed on an indicator, called Forage Production Index (FPI), calculated using a biophysical characterization of the grassland from medium spatial resolution remote sensing time series. We used the fCover integral as a surrogate […]

Schedule for SPOT4 (Take5) reprocessing

=> We should be able to start reprocessing  SPOT4(Take5) data in January, and to release them in February (it is always risky to announce a date, we have already announced November, then December). This new version will also be produced on MUSCATE prototype processing center, implemented at CNES, for the THEIA Land data center.   […]

La version v3.2 de l’OTB est sortie/ OTB v3.2 is out

Les collègues du CNES et de CS-SI viennent de sortir une nouvelle version de la bibliothèque open source Orfeo Tool Box. Parmi les améliorations, je suis sûr que vous serez nombreux à apprécier la segmentation « Large Scale Mean Shift », qui permet un traitement par tuiles qui donne le même résultat que celui qui serait obtenu […]
