A Design and Implementation of Lightweight ENC for Android App

摘要

A large ship has an expensive electronic chart display and information system (ECDIS) installed on its bridge for the safety of navigation and uses a variety of mobile equipment for auxiliary purposes. In contrast, small- and mid-sized vessels, passenger ships and fishing boats employ mobile equipment instead of such ECDISs, as their primary devices for navigation. Small-sized vessels only require some information and features of the ECDIS owing to the performance and resource restrictions of mobile devices and the characteristics of inshore or offshore navigation. This study proposed information lightening and indexing methods for electronic navigational charts to fit mobile equipment and implemented a tailored display configuration feature for navigators.
