Proactive mapping services for risk mitigation purposes delivered one month before Cyclone Nargis by RESPOND partner Keyobs to a Myanmar-based humanitarian user organisation. This image illustrates the coverage of the topographic maps delivered in April 2008: yellow indicates the areas mapped proactively by Keyobs (GIS data and mapping have been generated using conventional maps and 2007 Aster imagery); for comparison, the red indicates UNOSAT's post disaster initial assessment of areas affected by the cyclone.
