Observational sensors, such as CCTV cameras and radars, are part of the RIS system. These sensors should provide information about the current situation on the waterway and to a greater extent – aquatory. Barriers for the observational sensor, in the sense of reducing the view field, are various objects in the aquatory. This is one of the main factors that make it difficult to determine the proper location of the sensor. Currently, in order to increase the efficiency of determining the locations of the observational sensors are used different tools for performing spatial analysis. This applies to both the initial geographical identification as well as detailed analysis. Analysis efficiency, in turn, depends on the model of the environment, represented in the form of the Digital Surface Model. Given the complexity of some geographic features, it should be used the appropriate methodology for the visibility analysis, as well as the preparation of the input material. The following work includes the theme of visibility analysis on inland waters, with special emphasis on the complex objects. They include bridges, cranes, buildings, high vegetation and other engineering structures.
