Survey works on inland waterways can be contingently divided into two directions. The first ones are directed at maintaining the given dimensions of the waterway and are carried out with the use of technical fleet vessels, which includes the dredging fleet. At the same time the basis creation, the results verification and the control of the survey works implementation are carried out by the survey party. The main types of work here are surveying and trawling works, the implementation of which is carried out at the present time on the inland waterways of Russia using geo information technologies, which makes it possible to improve the quality and efficiency of their realization. Such an approach, firstly, has a positive effect on the implementation of the navigational hydrographic support system of navigators, including in the part of electronic cartography, and secondly, it allows to provide the survey works realization at the modern level. The most effective approaches and methods of modern geo information technologies application, implemented for the collection and processing of high-precision bathymetric information and positioning data to ensure the navigation safety on the inland waterways of the Russian Federation, are considered in the paper.
