Measurement Methodology


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.


Quick Recee


Quick Reconnaisance Survey of bench marks along the road from Mirchaiya of Siraha District to Katari of Udaypur district. The detail field report will be made availble below.

Preliminary Field


Pre-Field Study of some control points selected for measuring height of Mt. Everest has been conducted. Sollung, Chulyamu, Pike (Sub) HS and Pataale Danda has been inspected.

Consultation Workshop


Consultation Workshop for finalizing the methodology developed by Survey Department was conducted on 11-12 December 2017.
