In this paper, a method of mathematical description of a surface, which can be used for modeling the sea bottom and detecting underwater objects using sonar (a side scan sonar or a front one) or a multibeam echosounder, is presented. The method is based on Coons plates and is described in four steps, which can be used for determination of the sea bottom for spatial presentation and volume calculation. A new sounding vessel and its equipment were used for the collection of geospatial data, and the results of a geospatial model of the sea bottom on the basis of the collected data are shown. The sea bottom is presented using Coons surfaces and a triangulated irregular network.
