The Geohazards Thematic Exploitation Platform or Geohazards TEP is an ESA funded R&D activity to exploit the benefit of new techniques for large scale on demand processing of EO data. It supports the geohazards community which objectives have been defined in the context of the International Forum on Satellite EO and Geohazards in Santorini in 2012. Those objectives are addressed by creating an Exploitation Platform with Cloud-based models of collaboration where data providers, users and processors produce scientific and commercial exploitable results.
