Opis:
Shoreline mapping is one of the key stages in navigational charting. In terms of navigation, the shoreline marks the boundary of a river, which is often equivalent to the navigable water area. In cartographic terms, it is an important topological element between different objects that are adjacent to it. Currently, topographic objects are often mapped using photogrammetric materials obtained from various altitudes – satellite, airborne or low, which is associated with the use of an airborne UAV. Depending on the type of materials, the shoreline can be obtained in vector form with differing situational accuracy and differing degree of detail. In addition to the standard methods of processing vector data, the research in this paper also included the use of sonar images, enabling the detection of the shoreline with the use of a surveying hydrographic unit. On the basis of the collected photogrammetric and sonar images of different spatial resolution, an analysis of the accuracy of shoreline mapping was performed in terms of the situational accuracy and the level of detail in its representation. The results of the research provided the basis for the determination of dedicated remote sensing materials enabling the development of maps for inland navigation.

Unmanned aerial vehicle (UAV) technologies are becoming increasingly common, with ever-expanding applications. Low-altitude imaging makes it possible to quickly acquire high-resolution data for various objects, especially for mapping. This paper presents the mapping of a bridge and its notice marks, lights, and span to produce electronic navigation charts for inland navigation. The research object was the Clowy Bridge on the Regalica River in Szczecin, Poland. In order to carry out the research, two photogrammetric flights were made, and three sets of photos were created, from which orthophotos were developed. The research included the analysis of the orthophoto generation process, as well as quantitative and qualitative analyses. The results of the research demonstrated the possibility of using this type of data for mapping bridges to create electronic navigation maps for inland navigation.

Opis:
Conducting navigation by using electronic charts is not an option anymore. With few exceptions, vessels shall carry on board electronic navigational charts and Electronic Chart Display and Information Systems. The official electronic charts are issued by or on behalf of the authority of a Government, authorized Hydrographic Office or other relevant government institutions. These nautical charts are compiled from multiple data sources, some modern and very comprehensive, while others older. The accuracy of data, named “Category Zones of Confidence – CATZOC”, differs among various navigation areas. The navigation officers of the watch rely on the chart data to calculate the safety parameters and to plan the route in advance for the intended voyage. The aim of this paper is to emphasize the impact which the data accuracy has on the safety of navigation. For this purpose, a model vessel was considered in a Strait of Dover bridge simulation scenario, assuming good weather conditions without swell or current. The Safety Contour was defined using a mathematical formula which incorporated the under keel clearance, the squat effect and the tide levels. Then, the Safety Contour was examined considering the chart data accuracy. The results of this analysis contribute to increasing awareness and better understanding of CATZOC influences on the identification of safe waters during navigation.

Opis:
Virtual electronic aids to navigation are being introduced into the present short range aids to navigation system in the form of Automated Information System radio-based aids. Research is also underway into the development of their equivalents for use in regions that feature hostile environments, are poorly charted and lack any infrastructure whatsoever to support traditional or radio navigation aids. Such aids are entirely virtual in nature and exist only as a digital data object that resides within an electronic navigation chart for display to mariners through an Electronic Chart Display and Information System. They are at present experimental in nature, and are not intended to replace existing physical or radio-based aids to navigation. Results of research are described in terms of fulfilling traditional navigation aid functions and the development of new functions that are only possible using virtual aids. Their advantages in design and implementation are highlighted, as are their limitations and shortcomings as compared to present methodologies. Notable, however, is the approach used to overcome limitations and shortcomings by considering attributes of the physical environment to ensure their proper location and display of correct characteristics. Such an approach is unique in the modern world, yet it emulates ancient methods of navigation using known landmarks and terrain features.

NaAVIC, is a free and downloadable Electronic Chart System app specifically developed for boats of all sizes looking for safe and reliable professional navigation functionality on mobile devices and/or laptops. The app offers a range of features to make navigation easy and reliable, delivered through a clear and intuitive interface designed specifically for navigating at sea. The capabilities cover the range of essential features needed to maintain safety and situational awareness. Separate processes for download and update of the electronic chart data is not required because data is streamed in real-time from a cloud based open source database. The data is supplied to NaAVIC from Nautilus Cloud, a cloud based infrastructure designed for Marine Data, Solutions and Services for Government Organizations, Commercial Industry and Consumers. Nautilus Cloud is a “cloud native” approach and leverages high quality, open source components as its base technology. It uses open standards throughout to build a low-cost system which is flexible and has a much greater degree of interoperability with pre-existing components. A key feature of the Nautilus Cloud platform is the expansion of data holdings into a much wider family of related geospatial data products including the S-100 framework, harmonized metadata, raster and real-time sources. In essence, NaAVIC can operate on real-time and up-to-date information from charting agencies without a separate updating process. This enables the integration of real-time tides, weather, currents and other oceanographic information.

Opis:
Although SOLAS still requires nautical paper charts on pleasure crafts, more and more sailors prefer navigating digitally. What are the impacts on their spatial abilities? We conducted a field experiment at the Baltic coast and two simulator experiments with altogether 40 sailors. Participants plotted and/or piloted routes either in the classic manner on paper charts or digitally on an ECS. We assessed the situation awareness, the cognitive map, and (for the simulator only) the wayfinding with and without the navigation media. We found that digital navigation significantly impaired the cognitive map. Its impact on situation awareness, however, depended on previous navigation habits: Only sailors who used their paper charts regularly and actively benefitted from the ECS. We concluded that ECS navigation with its high level of automation lastingly alters spatial perception at sea and impairs orienting. With the vulnerable electricity supply on sailboats, this is a safety issue for shipping.
