SLN Chief Hydrographer and senior survey department officials inspect Bench Mark Network at NNA

The Chief Hydrographer of the Sri Lanka Navy, Rear Admiral Sisira Jayakody and senior officials of the Survey Department of Sri Lanka inspected the Bench Mark (BM) Network established by the SLN Hydrographic Survey Unit in the Nothern Naval Area (NNA) on 25th Sep 2015.  

The Bench Marks have been established at Kankasanthurai and Delft Island with a view to connect them to the National Bench Mark Network as an initial step towards re-establishing the Mean Sea Level (MSL) after 86 years.

Sri Lanka Navy Hydrographic Survey Unit headed by LCdr EMA Bandara initiated the project under the guidance of Rear Admiral Sisira Jayakody in 2014. So far, the unit has established Bench Marks covering all four corners of the island alongside 24 hours tide monitoring stations. The unit is planning to extend the network further. Appreciating the Navy’s project that carries national importance, the officials of Survey Department agreed to work in close collaboration with the navy.

Identifying the requirement of broadening the potentialities of the Hydrographic Survey Unit of the SLN in order to effectively carry out hydrographic related activities coordinating with outside organizations, Rear Admiral Jayakody was appointed as the first ever Chief Hydrographer of the SLN history by the Commander of the navy, Vice Admiral Ravindra Wijegunaratne.
