Abstract
Techniques updating bottom topographical data are described. Positional data from a RTK-GPS are transformed to rectangular coordinates by the Gauss-Krüger Projection, and synchronized with depth data from an echo-sounder to generate three dimensional topographical data. A bottom topography over a triangular mesh is updated by two methods. Errors due to the movement of a boat are corrected by outcomes from a clinometers and a compass.
