Precise levelling is conducted to carry height from the southern plains of Nepal to the selected control points.
Trignometrical levelling is performed from selected control points(points to which height is carried by precise levelling).
Gravity survey will be conducted to define the local geoid around the Everest
GNSS based survey is conducted for determining locations of gravity points, bench marks as well as top of Sagarmatha.
Consultation Workshop for finalizing the methodology developed by Survey Department was conducted on 11-12 December 2017. The workshop finalized the methodology on the base of which field work will be followed. The final methodology will be made available for download below.
