The Ministry’s survey division are currently working on cleaning up trig stations in Nadroga, Serua and Namosi Province.
A trignometrical station or trig is a permanent surveying station. These are reference points established by the Ministry’s geodetic surveyors with coordinates and elevation for origin of survey work.
It connects surveyors work to maintain high survey accuracy, avoiding boundary encroachment.
These stations are located on mountains, hilltops for the purposes of visibility at lower ground elevation.
Trig stations are used to support surveying of property boundaries, civil and structural engineering works, geospatial activities, hydrographic survey, topographical survey, etc.
Four Survey staff from the Navua bubble were tasked to clean and paint the trig stations and beacons in these provinces.
To date, the team has attended to 3 Stations namely Korolevu, Kavanagasau, Korolevu ,Malomalo and Senilabuli, Yako.
Periodic maintenance is carried out to ensure the marks are stable with clear visibility from all directions.
The team also carries out monitoring of sites with trig stations as many cellular transmission masts are being built near the trig stations.
The stations are not easily accessible by vehicle the teams have to walk right up to the stations, which may take hours to reach.
