Opis:
Elektroniczne mapy nawigacyjne (Electronic Navigational Charts) są obecnie najbardziej popularnym i szybko rozwijającym się cyfrowym produktem hydrograficznym. Według obowiązujących przepisów są one jedynymi mapami elektronicznymi, które dają prawną możliwość przejścia do nawigacji „bezpapierowej”. Proces tworzenia ENC jest zadaniem czasochłonnym, co związane jest w znacznej mierze z pozyskaniem oraz edycją danych geoprzestrzennych. Aby dane te były przydatne muszą spełniać kilka podstawowych warunków. Przede wszystkim każdy element musi być kartowany z zachowaniem odpowiednich wymagań odnośnie dokładności sytuacyjnej oraz batymetrycznej. Oprócz tego, obiekty muszą posiadać niezbędne atrybuty, które są szczegółowo zdefiniowane w obowiązujących standardach. Dodatkowo dane powinny być aktualne oraz, ze względu na ich liczbę, usystematyzowane i łatwe w zarządzaniu. W związku z powyższym, autorzy pracy wykorzystali i zweryfikowali w procesie tworzenia map elektronicznych geobazę danych, która jest jednym z podstawowych produktów rodziny oprogramowania ESRI. W podstawowej funkcjonalności geobaza umożliwia tworzenie obiektów, ich modyfikację, ładowanie obiektów istniejących, tworzenie relacji topologicznych, tworzenie podtypów i domen atrybutów czy kontrolę poprawności wprowadzanych danych. Opracowana przez autorów niniejszej pracy geobaza danych składała się z zestawów danych oraz klas obiektów. Zestawy danych odpowiadały strukturze tematycznych kategorii natomiast klasy obiektów – obiektom tworzącym mapę nawigacyjną. Obiekty były kodowane zgodnie z obowiązującymi standardami tworzenia map elektronicznych dla żeglugi śródlądowej, a dokładnie dotyczyło to uwzględnienia odpowiedniej geometrii oraz predefiniowanych atrybutów. W celu zwiększenia dokładności edycji danych, zdefiniowano podtypy obiektów oraz ich domeny, co również usprawniło zarządzanie danymi oraz ich ewentualną modyfikację czy tworzenie. W etapie końcowym dokonano oceny geobazy danych, jako produktu wykorzystanego w procesie produkcji map elektronicznych dla żeglugi śródlądowej. Przedstawiona metoda opracowywania danych wskazuje na możliwość wykorzystania oprogramowania środowiska GIS o podstawowej funkcjonalności w procesie tworzenia map elektronicznych. Dane w tej postaci w późniejszym etapie mogą zostać skompilowane za pomocą dedykowanego
Electronic Navigational Charts are currently the most popular and fast developing digital hydrographic product. Officially, they are the only electronic charts which enable a legal change to paperless navigation. The process of ENC creation is time-consuming, which is largely due to data acquisition and edition.For ENC geodata to be useful they should meet several conditions. First of all each element must be charted with maintenance of proper requirements relative to situational and bathymetric accuracy. Apart from this, all geographic features must have necessary attributes, which are defined and described in valid standards. Additionally, data should be up-to-date and, in view of their number, ordered and easy in management. Realization of all the above conditions is possible by application proper software of GIS environment. The authors of this paper have used and verified in chart creation process ageodatabase, which is one of the basic products of the ESRI software. In its basic functionality a geodatabase enables creation of feature classes, their modification, loading of other data, creation of topology relation, creation of subtypes and attribute domains or control of correctness of new data. The geodatabase elaborated by the authors of this work consists of feature datasets and feature classes. Feature datasets corresponded to the structure of thematic categories, whereas feature classes corresponded to geographic objects which created navigational charts. All features were coded according to valid standards of electronic chart creation for inland shipping. The concern was mostly with compliance to proper geometry and predefined attributes. For limiting of data error, subtypes and attribute domains were predefined, which also improved data management and their modification and creation. In the last stage the geodatabase was assessed as a product used in the process of IENC production. The presented method of data elaboration shows the possibility of application of the GIS environment software and its basic functionality in IENC map creation. Data in this form can be compiled with the use of dedicated hydrographic software to obtain interoperable format based on S-57 standard. Practically, data compilation was done by the Hydrographic Office of the Polish Navy. This method of map production enabled to obtain the first in Poland inland electronic chart.

Opis:
Obecnie coraz częściej do opracowania różnych map wykorzystuje się cyfrowe zobrazowania teledetekcyjne. Dotyczy to także map nawigacyjnych, które wypierają analogowe mapy papierowe. Szczególne znaczenie ma to w przypadku opracowania map dla żeglugi śródlądowej, ponieważ do tej pory nie opracowano nawet ich wersji papierowych. Wykorzystanie materiałów teledetekcyjnych do pozyskiwania danych w postaci wektorowej wymaga odpowiedniej wiedzy i doświadczenia, co z kolei przekłada się na dokładność kartowania obiektów geograficznych. W szczególności dotyczy to linii brzegowej oraz elementów topografii mających duże znaczenie dla nawigacji. Niestety, obecnie nie ma wytycznych co do wykorzystania tych materiałów do tworzenia czy uaktualniania map nawigacyjnych. W związku z tym autorzy niniejszej pracy przeprowadzili badania związane z możliwością wykorzystania zdjęć lotniczych oraz obrazów satelitarnych do kartowania obiektów topograficznych, na przykładzie linii brzegowej oraz mostów. Pozyskane obiekty na drodze wektoryzacji zostały zweryfikowane pomiarami bezpośrednimi, co z kolei umożliwiło określenie ich dokładności sytuacyjnej oraz skonfrontowanie jej z wymaganiami hydrograficznymi. Dodatkowo poddano ocenie potencjał interpretacyjny zobrazowań, który niewątpliwie stanowi istotny czynnik podczas opracowywania map nawigacyjnych.
Digital remote sensing images are currently used to prepare various maps, including navigational charts, which are more and more frequently used in place of paper products. A particularly important application of remote sensing images is the preparation of maps for inland shipping, because up till now there are no navigational charts, even in paper form. The use of remote sensing products to acquire information on geographical features in vector form requires proper knowledge and experience, which is tightly correlated with their final accuracy. This problem is particularly relevant as regards shorelines and topographic elements which have a significant role in navigation. Unfortunately, there is no recommendation concerning the application of these data to the creation and updating of navigational charts. Therefore the authors of this paper studied the range of applications for charting topographical features for example shorelines and bridges from aerial photographs and satellite images. Digital vector objects were verified by field measurements, which permitted the determination of their horizontal accuracy and further comparison with hydrographical requirements. In addition to this, their interpretation potential was studied, which is for certain an essential consideration in the preparation of navigational maps.

Opis:
Advances in ocean modelling have led to improved performance for operational ocean forecasting and the availability of continuously reliable forecast information for certain ocean regions of the world. Although such forecasts are being increasingly adopted into a wide range of services across the maritime industry they have not yet been considered as candidates to supplement or to substitute conventional tide tables for navigation use. The issue is important in the context of climate change and the added uncertainty now placed on the use of conventional tide table for navigation in complex coastal waters. In the context of e-navigation it is timely to begin to explore the issue and examine how such forecasts might be used and adopted. This requires closer connectivity between ocean forecasting and navigation communities and the involvement of overarching organisations such as IMO and I GOOS. This paper raises the issue and opens the debate.

Opis:
The current systems supporting navigation on board of ships are built on the classic concept for equipment: The system is developed, tested, type approved, installed and from that time on used with no or little modifications. Looking at other industries a regime of software and system maintenance has been established which allows more rapid updates. The development in the IT arena moves more towards modular approached, encapsulating individual components for easier implementation and delivery with limited system wide impact. This key concept is lately often referred to as the “app concept”. The e-Navigation development asks for exactly that: a way to improve innovation while ensuring system stability for the navigational components used by the navigator on the bridge. A key aspect of the success of new systems will be the ability to convert data into as information as needed in any given situation, creating knowledge for intelligent decisions increasing the competence of a navigator. The paper will focus on the following topics: – The classic “monolithic” Equipment paradigm – Modern System Architecture using components and “apps”-concept – Advantages of an approach using situational driven tool enhancements – The “app”-concept supporting the situational centric information presentation.

The maritime high speed craft navigators` ultimate aim has for decades been to safely and efficient navigate the vessel to its destination. The last decade an increased use of technology has arrived at the maritime ship bridge. The use of Electronic Charts and Integrated Navigation Systems has revolutionized much of the work of the navigator, with the aim of enhancing the safety of navigation. The amount of information has drastically increased, and the need for a proper information management and an efficient visual scan pattern has been identified. Looking to other industries this has been introduced with success, and in this paper the authors present a proposed scan pattern for the maritime navigator. The analysis is based on an eye tracking data set collected from simulator- and field studies on board the world’s fastest littoral combat ship.

Opis:
The Electronic Chart Display and Information System (ECDIS) became the central navigational tool on modern ships. The system comprises numerous navigational and other components, each of them with its limitations and reliability. Due to ECDIS's revolutionary features, navigators are tempted to place excessive reliance on the system. Such reliance on it as a sole navigational aid is undoubtedly a problematic issue. The proposed paper is a segment of a systematically carried out research among ECDIS stakeholders. ECDIS EHO (Experience, Handling, and Opinion) research aims through research activities based on a user-centred approach to develop and improve the educational framework. The overreliance on the ECDIS system motivated the proposed research, which focused on system users' opinions and practice regarding confirmation of the accuracy of information displayed on ECDIS, particularly concerning positional sensors. Analysis of answers collected by the ECDIS EHO questionnaire represents a backbone of the research supported by previous achievements. The answers have been categorized and discussed, revealing certain worrying aspects referring to the system's positional error experienced by users. Furthermore, preferred methods of cross-checking ECDIS information have been identified and have differed among respondents based on their rank on board. Additionally, answers indicate certain doubts between users’ interpretation of the best confirmation method and the actual selection of the used method. The importance of cross-checking navigational data in avoiding overreliance and maintaining situational awareness has been presented in the conclusion chapter and the proposal for further work.

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:
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:
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.

Opis:
An electronic system and an algorithm for estimating pedestrian geographic location in urban terrain is reported in the paper. Different sources of kinematic and positioning data are acquired (i.e.: accelerometer, gyroscope, GPS receiver, raster maps of terrain) and jointly processed by a Monte-Carlo simulation algorithm based on the particle filtering scheme. These data are processed and fused to estimate the most probable geographical location of the user. A prototype system was designed, built and tested with a view to aiding blind pedestrians. It was shown in the conducted field trials that the method yields superior results to sole GPS readouts. Moreover, the estimated location of the user can be effectively sustained when GPS fixes are not available (e.g. tunnels).

By incorporating the eye tracking techniques into the procedure it was possible to measure the visual attention distribution and the cognitive work-load. The presented method could be used to evaluate usability of every e-navigation system, which is necessary to ensure that the seafarers are able to successfully perform primary operations of systems upgraded with e-navigation functions, regardless of the type and specifications of the system and users’ knowledge and experience with the system. The initial results are presented and discussed as the study is still ongoing.
