A2S mission is to innovate services for Geosciences applications through data-intensive computation and the development of downstream services issued of Satellite Earth observation data. A2S develops and operates high performance computing, data analysis using artificial intelligence and data storage through its partnership with datacentres and high-level research institutes. If you need to extract knowledge from Earth Observations (EO), we engineer and operate downstream services for series of sensor data with scalable processors, hosted processing, and the more advanced algorithms of the research sector. Expertises:Massive computing, Time series analysis, Satellite derived products, Software development. A2S operates computation clusters, storage capabilities and dedicated high-level science driven algorithms for detecting changes in in time series of both geospatial datasets and in-situ sensors using advanced ICT, AI and Cloud/HPC technologies. Services: Fully automated processing of massive datasets for change detection applications. A2S develops, manufactures, optimizes and integrates R&D processing algorithms on large calculation clusters.
