Abstract
This study demonstrates numerical techniques for a topographic study of a water area. Data obtained by a GPS unit and an echo sounder were combined, and three dimensional data were generated. A problem to find a surface that contains those data points was reformulated to a problem to find a piecewise linear continuous function defined over a triangular mesh. An iterative method led to an approximation of a fixed point. Those techniques are illustrated, and numerical examples are introduced.
