The article presents problems of verifying DTM creating methods on the basis of real sounding data. There has been presented a concept of solving these problems by applying virtual hydrostatic sounding. A method has been worked out of simulating a single and multibeam echosounder taking into account vessel movement and transducer parameters. Elements of ray tracing have been used in the algorithm. The method proposed may be a valuable research tool in methods of creating DTM and in planning real marine soundings.
