| Abstract: | Based on detailed analysis of latest data standard of IHO S-57 (transfer standard for digital hydrographic data, Edition 3), according to IHO S-52 specification for chart content and display aspects of ECDIS and IMO performance standards, the methods of receiving the standard electronic navigational chart and transforming it into system electronic navigational chart which can efficiently support display, storage, and manipulation of electronic chart are studied. And a design scheme of system electronic navigational chart is (also) presented. In addition to chart data files, the scheme involves index tables of elements, catalogue of (elements), display priority of catalogue of elements and levels of elements. Finally, the scheme has been (successfully) implemented with Visual C++, as a result, the correctness and reasonableness of it has been verified. |
