The study of the upper part of the seismic section is an important task for seismic surveys on land and sea, both in oil and gas exploration and in solving engineering problems as well as in monitoring of dangerous geological processes. Information about the structure of the upper part of the seismic section can be extracted from the analysis of surface waves that propagate in near-surface media, have a large amplitude and in many cases constitute a significant part of the recorded wave field. The most used method for surface wave acquisition and analysis is multichannel analysis of surface waves (MASW). However, it is not possible to set the remote studies: the sources and receivers should be set just under the investigated area. The method of surface-wave tomography makes it possible to carry such studies. The advantages of surface-wave tomography for engineering problems are discussed with several numerical examples. The main advantage - the method of surface wave tomography makes it possible to study various engineering and geological objects remotely. This has tremendous perspectives for land and marine seismic exploration to study the environments under closed or protected objects, pipelines, drilling platforms, etc.
