They added at the time that a ground survey and GPS or an airborne mission would be needed to determine whether the world's highest peak had seen a change in its height by a few centimetres.They added at the time that a ground survey and GPS or an airborne mission would be needed to determine whether the world's highest peak had seen a change in its height by a few centimetres.
Mr Rao told the Press Trust of India news agency that the team would take about a month to make its observations and another 15 days to compute and declare its data. Mr Rao told the BBC: "The Survey of India will work with the government of Nepal, which has agreed in principle to collaborate."
Everest's height will be assessed using a combination of GPS measurement and triangulation.
Mr Rao said it was an open question whether the quake had affected Everest's height.
"We don't know what happened, there's been no confirmed report. Some scientists do believe it has shrunk. But there's a school of thought it may have grown."
There will be about 30 people in the team, including three or four Indian scientists.
