The Global Exposure database is being produced for the Global Risk Assessment 2013, part of the Global Assessment Report 2013 (GAR 2013). It aims to map at a granular geographical level the world's capital stock in urban areas. It is designed primarily to assess the risk of economic losses as consequence of natural hazards at a global scale. The Global Exposure database for GAR 2013 (GEG-2013) is an open exposure global dataset at 5 km spatial resolution which integrates population and country-specific building typology, use and value. It is currently suitable mainly for earthquakes and cyclones probabilistic risk modeling using the CAPRA platform (http://www.ecapra.org). This paper describes the development of the GEG-2013. The database is based on a top-down or downscaling approach of national/regional socio-economic and building type information. These information are transposed onto a regular raster damsel. (grid formal.) using a geographic population distribution model as a proxy. (C) 2014 Published by Elsevier Ltd.
