    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.

    Opis:
    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:
    Navigational charts are essential tools for marine navigation. But how accurate are the navigational charts that we use when going sailing? Do we really know how much faith can be placed in them? All charts, whether paper or electronic, contain data, which varies in quality due to the age and accuracy of individual surveys. In general, remote areas away from shipping routes tend to be less well surveyed, and less frequently, while areas of high commercial traffic are re-surveyed frequently to very high levels of accuracy, particularly where under-keel clearances are small. It is quite accurate to consider a chart as a jigsaw of individual surveys pieced together to form a single image. Having the necessary skills to determine how much confidence should be placed in the surveys, which combine to form a chart, should be a requirement for any sailor venturing into unfamiliar waters. When the International Hydrographic Organization (IHO) developed the S-57 standard for Electronic Navigational Charts (ENCs), this problem was recognized and it was decided that the quality of survey data used to compile ENCs had to be encoded within a composite data quality indicator ‘Category of Zone of Confidence’ (CATZOC) to assist seafarers in assessing hydrographic survey data and the associated level of risk of navigating in a particular area. According to IHO S-67, the accuracy of Electronic Navigational Charts is not impressive and leaves much to be desired. The author discusses these apparent shortcomings of ENCs and present erroneous approaches to this problem, so common in the seafaring community.
