China seeks US satellite quake data 

China asked the United States for satellite images of quake-stricken Sichuan province to help locate victims and identify seriously damaged roads and infrastructure, US and Chinese officials said.
   
The request, hand-delivered to the State Department by a Chinese embassy official, seeks high-resolution imagery of the region surrounding the south-central Chinese city of Chengdu, officials said.
   
A State Department spokesman had no immediate comment on how the United States would respond to the request but officials said it was expected to receive a high priority.
   
A US document obtained by Reuters said China has already received offers of advanced satellite imagery from Japan as well as offers of radar data from Canada and Italy through the International Charter on Space and Major Disasters.
   
The Pentagon espionage unit known as the National Geospatial-Intelligence Agency, or NGA, has already begun analysing imagery of the earthquake's aftermath taken from US spy satellites, according to defence officials.
   
The Bush administration has offered spy satellite images and analysis to foreign governments coping with natural disaster in recent years to help organize rescue and recovery operations.
   
The State Department would also likely seek imagery for China from civilian government satellite, such as the US Geological Survey as well as private-sector satellite companies, especially before-and-after images of quake-stricken sites, officials said.
   
The death toll from China's earthquake could soar to more than 50,000, state media reported on Thursday.

Some 20,000 are confirmed dead after Monday's 7.9 magnitude quake and 25,000 were buried in areas rescuers have struggled to reach, battling landslides, buckled roads and collapsed bridges.
   
Half the epicentre town of Yingxiu, where corpses are lined along the river, has been flattened and 90% of the buildings remaining look unsafe.
   
US satellite imagery could produce highly detailed pictures of damage to roads, railways, tunnels, ports and coastlines.
   
A official at the Chinese embassy in Washington said the data could also help save lives by locating desperate victims.
