NASA and space agencies around the world are pointing theirsatellites toward Haiti to aid relief efforts and map damage caused by the devastatingearthquake earlier this week.

The 7.0magnitude quake struck the Caribbean island Tuesday, causing extensive destructionand fatalities estimated in the tens of thousands.

NASA?s Advanced Spaceborne Thermal Emission and ReflectionRadiometer (ASTER), a joint project with Japan, and its Earth Observing-1(EO-1) satellite are taking images of Haiti?s hardest-hit areas in multiplewavelengths of light.

Ground teams are comparing these pictures to pre-quakephotos to assess the damage, and to help rescue and relief workers know whereto focus their efforts, agency officials said.

A network of satellites working for the InternationalCharter on Space and Major Disasters has also joined the endeavor. The EuropeanSpace Agency, the French Space Agency (CNES), Japan, China, Canada and the U.S.have all pitched in under the charter.

Additionally, Germany, Italy and South Korea have alsodonated satellite time.

The resulting images show widespread ruin aroundPort-au-Prince, Haiti?s capital and largest city. The earthquake struckjust 10 miles (15 km) southwest of the city.

European researchers combined data from severalinternational satellites top build a so-called ?damage elevation map? that illustrateswhich regions of Haiti have seen the most damage. In the image, the mostobvious damage in Port-au-Prince can be seen in red.

?As soon as new data arrives, updated maps will be producedand made available to the international community,? ESA officials said.
