Perspectives For Vhr Big Data Image Processing And Analytics Toward A Dedicated Framework For Major Disaster And Environment Monitoring From Space

Through various initiatives, CNES, the French space agency, has been involved in major disaster and environment monitoring from Space for many years and in particular in the International Charter which delivers satellite data to nations affected by major disasters and in the THEIA organization which promotes the use of satellite data to monitor human and climate impacts on environment.Thus, CNES developed in 2014 a reference framework to generate value-added products from satellite data. Since 2017, considering the increase of data and processing requests, CNES has decided to move to a new framework based on big data and cloud technologies and extended to data analytics.This paper will first introduce THEIA and Charter initiatives. It will present the current framework in operation and its limitations. It will then focus on the innovative approach to handle big data and analytics needs and finally presents the first results and perspectives.
