This document summarizes Geoff Sawyer's presentation on big data challenges for secure societies from an industry perspective. It provides information about EARSC, a network of commercial remote sensing companies in Europe. EARSC envisions establishing a European Marketplace Alliance for Earth Observation Services (MAEOS) to help overcome fragmentation in the European industry and enable companies to develop business globally. MAEOS would provide services like a common identity, governance policies, and market support. An operational marketplace called EOMall could also be established under MAEOS to facilitate transactions between buyers and sellers.
