Abstrakt: This article presents possible applications of a dynamic gravity meter (MGS-6, Micro-g LaCoste) for determining the dynamic height along the Odra River, in northwest Poland. The gravity measurement campaign described in this article was conducted on a small, hybrid-powered survey vessel (overall length: 9.5 m). We discuss a method for processing the results of gravimetric measurements performed on a mobile platform affected by strong external disturbances. Because measurement noise in most cases consists of signals caused by non-ideal observation conditions, careful attempts were made to analyze and eliminate the noise. Two different data processing strategies were implemented, one for a 20 Hz gravity data stream and another for a 1 Hz data stream. A comparison of the achieved results is presented. A height reference level, consistent for the entire estuary, is critical for the construction of a safe waterway system, including 3D navigation with the dynamic estimation of under-keel clearance on the Odra and other Polish rivers. The campaign was conducted in an area where the accuracy of measurements (levelling and gravimetric) is of key importance for shipping safety. The shores in the presented area of interest are swampy, so watercraft-based measurements are preferred. The method described in the article can be successfully applied to measurements in all near-zero-depth areas.

Abstrakt: Video surveillance on both marine and inland waters still only plays a mainly auxiliary role in vessel traffic observation and management. The newest technical achievements in visual systems allow camera images to be used in more sophisticated tasks, such as automatic vessel recognition and identification in observed areas. With the use of deep learning algorithms and other artificial intelligence methods, such as rough sets and fuzzy sets, new functions can be designed and implemented in monitoring systems. In this paper the challenges that were encountered and the technology that has been developed in managing video streams are presented as well as the images needed for tests and proper operation of the designed Ship Recognition and Identification System (SHREC). The current technologies, typical setups and capabilities of cameras, with regard to existing on-water video monitoring systems, are also presented. The aspects of collecting the test data in the Szczecin Water Junction area are also described. The main part of the article focuses on presenting the video data pre-processing, storing and managing procedures that have been developed for the purposes of the SHREC system.

Abstrakt: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.

Abstrakt: Route monitoring is one of the most important functions in modern navigation systems. In case of marine merchant ship’s it usually part of IMO-standardized solutions like ECDIS or INS. In inland waters Inland ECDIS is implemented. There is however large group of ships which do not have to follow standardized solution, like recreational ships. The skippers of these boats more and more often are using mobile devices. The paper presents considerations on implementation of voyage assistant module in mobile navigation system in inland waters. Main problems are defined solutions for them are proposed. In general proposed approach is based on mobile cartography like in car navigation and derives also from water navigation systems. The verification research are described and commented.

kluczowe: nawigacja śródlądowa, nawigacja mobilna, mobilna kartografia, prezentacja kartograficzna
Abstrakt: Obecnie prawie codziennie każdy, kto posiada urządzenie typu smartphone, wspomaga się aplikacjami mapowymi, które we współpracy z wbudowanym modułem GPS umożliwiają łatwą lokalizację obiektów, wytyczenie trasy czy nawigowanie do celu. Aplikacja MOBINAV jest jedną z tego typu aplikacji, dedykowaną prowadzeniu nawigacji na wodach śródlądowych, w głównej mierze przez użytkowników rekreacyjnych. Przekaz kartograficzny aplikacji mobilnych jest dynamiczny i bardziej skomplikowany w porównaniu do tradycyjnego. Sama mapa zmienia się pod wpływem czynników zależnych od użytkownika i jego wymagań lub/oraz pod wpływem zdarzeń generowanych w trakcie realizacji nawigacji. Autorzy systemu MOBINAV opracowali model kartograficzny opierając się na dostępnych rozwiązaniach wprowadzonych w nawigacjach samochodowych lub pieszych oraz biorąc pod uwagę wymagania użytkowników, otrzymane na podstawie stosownej ankiety. Model ten zakłada 2 prezentacje kartograficzne ze względu na rodzaj urządzenia: smartphone/tablet oraz HUD. Na pierwszych prezentowana jest mapa wraz z wszystkimi jej komponentami, natomiast wizualizacja dla HUD zawiera elementy trasy jako główną treść przekazu kartograficznego. Pod pojęciem przekazu kartograficznego systemu MOBINAV należy rozumieć logikę treści, czyli dobór elementów składających się na treść mapy (geokompozycja) dla konkretnego przypadku użycia i w odpowiedniej skali oraz logika systemu znaków i symboli, czyli stylizacja mapy – doborem kolorów poszczególnych obiektów, projektem systemu znaków i symboli reprezentujących obiekty punktowe, przy zachowaniu zasady izomorfizmu treści i postaci. Efektywność, funkcjonalność i użyteczność przekazu kartograficznego systemu MOBINAV poddana została weryfikacji przez potencjalnych użytkowników aplikacji za pomocą ankiety internetowej. Wyniki ankiety pozwoliły na dokonanie pełnej oceny, wyciągnięcie wniosków oraz zaplanowanie dalszych prac nad rozwojem i udoskonaleniem aspektów aplikacji związanych z przekazem kartograficznym.

Abstrakt: Mobile devices are increasingly popular among recreational water users and for navigational purposes. Making full use of the possibilities they offer requires a navigational system to be designed and built for mobile devices which make use of mobile cartography. A dynamically adaptive mobile presentation model offering various display possibilities may be an appropriate example of such a system. The navigational purpose of the system, however, requires that the main navigational data presented are integrated in one place, in a so-called conning display. These data should be easily accessible to the user, which is not always the case with mobile devices. The idea of using a Head-Up Display (HUD) as a conning display in a mobile navigation system arose from these considerations. The current paper presents research on implementing a HUD into a mobile system. First, the idea of mobile cartographic presentation is discussed, then the navigational data available in the system are presented. Finally, the concept of using a HUD is explained, a HUD presentation model is shown and technical aspects of HUD integration are described.
