This paper describes how the Group on Earth Observations (GEO) and the Committee on Earth Observation Satellites (CEOS) are individually and collaboratively strengthening worldwide ability for agencies to manage the disasters lifecycle. The Architecture Implementation Pilot (AIP) of GEO has, through an agile development process, deployed and tested advanced information systems for Earth Observations based on interoperability arrangements. In particular, AIP has focused on several disaster management scenarios resulting in an architecture that has improved the ready viability and usability of data for disasters. CEOS is constructing a reference architecture, intended to streamline access to satellite data and services for disaster management and risk assessment. The CEOS approach aims to support disaster management activities with satellite information in a holistic fashion, taking account of their overlaps and interdependencies. Jointly GEO and CEOS are now working to align the approaches for disaster management to describe enterprise components and improve understanding of contributed systems and their roles. The coordination has lead to refinements of the Disaster Management Scenario via further implementation in AIP-5. By collaborating via the CEOS working groups and the Global Earth Observing System of Systems (GEOSS) communities of practice, these efforts are intended to engage the international community focused on disaster management and risk assessment to fully utilize remote sensing resources for societal benefit.
