The use of the EVOLVE testbed, which contains HPC features, will be extremely useful, allowing better accuracy and improved response times.
The repetitiveness (every few days) and the free access of Sentinel-2 (S2) satellite images result in massive datasets. Examining changes of a designated area over a period of time through these high-resolution images (10m per pixel), enables applications in many sectors, such as security, emergency, marine and land surveillance. An important challenge in multi-temporal change detection is fast access and storage of a big amount of data and the computationally-intensive processing which is necessary. Furthermore, another challenge of change detection is sensitivity to atmospheric distortions, such as cloud or aerosol optical thickness.
