The article is devoted to the development of methods for mapping the bottom of shallow water bodies by laser bathymetry. The problem of developing a method for mapping the topography of the bottom of shallow water bodies has been formulated and solved. The emitter is a laser mounted on board the aircraft. Based on the geometric representation of the path of optical beams in laser bathymetry and the analysis of known measurement results, a stepped model of the bottom of a reservoir is proposed, the height and width of the steps of which vary over a wide range. Based on the well-known method of mapping the bottom of a shallow water body from one point, a two-point measurement method using a stepped bottom model is proposed. The conducted modeling studies have shown that the measurement error of the proposed method is within ±4.5%.
