Elaboration of Digital Bottom Models on the Basis of Single Beam Acoustic Measurements with Different Resolution

The paper presents results of the experiments carried out on the 40 ha part of the Lake Śniardwy using satellite and hydrographic integrated technology. Bathymetric survey at the Lake Śniardwy has been conducted with the measurement profiles designed every 50 meters and 5 meters one after another. The collected data have been elaborated with spatial interpolation method called kriging in order to create Digital Bottom Model. The results of conducted experiments show comparison of two bottom models created on the basis of 50 m and 5 m profiles.
