Digital terrain models (DTMs), finding a wide range of applications in the exploration of water areas, are mainly created on the basis of bathymetric data from a multibeam echosounder. The estimation of DTM accuracy dependent on the choice of the survey parameters is difficult due to the lack of reference surface. These authors have developed the methodology of simulation called virtual survey, which enables examining how various parameters of the echosounder, survey and DTM construction algorithms affect the errors of the created models. They are aimed at precise estimation of the model accuracy and the optimization of depth measurement work. In this paper, the influence of profiles acquired during marine survey on the accuracy of created models has been investigated. The research included vertical, horizontal, diagonal and mixed orientations. As an effect of experiments we come to the conclusion that extending the sounding with additional profiles in a different orientation has a very small influence on the accuracy and is suggested only in some special cases.
