The free and open data policy and data access concept for the Sentinel missions may lead to the development of particular, yet unforeseen, "apps" (application software) by and for the general public.
Such developments are not only possible but encouraged. Their availability will be advertised within the core ground segment. In some cases, according to available operational resources and budget, processing capability through hosting processing (eg. user exploitation platform) may be provided.
Such collaborative modes will be particularly encouraged wherever a resulting decrease of dissemination data volume can be demonstrated.
