Abstract:
Relative geoid of central Sri Lanka has been calculated adding contributions due to the Bouguer anomaly and topographic features
over the region. A Fourier technique which makes use of fast Fourier algorithms was used to obtain the topographic component
instead of classical gravimetric approach which is based on Stokes-Helmet method. These computations show that the relative geoid of central Sri Lanka is entirely positive with a maximum of 5.9 m close
to Nuwara Eliya.
