Abstract: Earth Observation (EO) remote sensing missions are producing an increasing volume of data due to higher spatial and spectral resolutions, and higher frequency of acquisitions. To prepare new EO missions, CNES, the French space agency, develop in partnership with CS a demonstrator that aims at implementing and validating image processing chains using Big Data and Cloud technologies in an environment similar to an operational image processing center. The image processing pipeline chosen for the study is a 3D image processing chain that will be used for a future earth observation mission. The demonstrator is currently being tested at a large scale on various Cloud infrastructures with numerous stereo and tri-stereo images.
