Numerical study of underwater topography with measurement data

This study demonstrates the application of numerical techniques to recent measurements concerning underwater topography. The Gauss-Krüger projection transformed latitude and longitude components of GPS data to rectangular coordinates. Combination with vertical components including echo sounder output generated curves in an underwater topography. Fixed point iterations on nodal values of triangular meshes gave rise to a surface that is suitable for measurement. Those techniques were also applied to previous data for comparison.
