FIELD: physics.
SUBSTANCE: disclosed method employs reference depths and coordinates (depths and coordinates on the surveyed water body) and calculation of increments of depths and coordinates as a difference between two adjacent distance vectors measured by a multi-beam echo sounder. That way, each depth and its geodesic coordinates are calculated as a sum of increments of adjacent depths and their geodesic coordinates, starting with the depth and geodesic coordinates of the point of the reference depth. A device for realising the method is also disclosed.
EFFECT: high accuracy of surveying the bottom topography.
