Earth observation satellites have provided vital information to relief workers in Myanmar throughout a particularly long crisis response window following the devastating Cyclone Nargis that hit the country on 2 and 3 May 2008.

Immediately after the disaster, the UN Office for the Coordination of Humanitarian Affairs (OCHA) asked the International Charter on 'Space and Major Disasters', referred to as 'the Charter', for support by providing immediate crisis mapping of the affected areas.

Following the request, rapid mapping products were created with Earth observation (EO) satellite acquisitions taken in the wake of the event to derive an estimation of the flood surge impact and other damage information to help plan emergency response operations.

Damage maps were able to be created quickly because the RESPOND project, which delivers satellite mapping for disaster reduction and humanitarian aid, had delivered EO-derived topographic maps of Myanmar a month before the disaster.

This activity was part of a project to help local communities reduce exposure to disaster risks. This enabled the RESPOND team to compare up-to-date basic maps before the disaster with satellite images acquired during or after the cyclone impact.

Thanks to the Charter more than 10 different sensors radar and optical from several EO missions provided more than 60 satellite images, which were used to derive 29 damage maps.

These maps were provided to the UN community in Myanmar and Bangkok for the emergency response phase, which lasted more than 40 days because of the scale of devastation caused by Nargis and the difficulties encountered by the international humanitarian community to access the country.

To provide aid workers with timely and synoptic damage information, space agencies and service providers worked around the clock. RESPOND's partner UNOSAT UN provider of EO mapping services to the humanitarian aid community ca
