With the development of hydrographical work and information techniques, digital charts are more and more popular in maritime applications, and an embedded product--PDA (personal digital assistant) is widely used in navigation for its smallness and portability. However, there is lack of PDA-based product which can provide integrated data management, real-time alternate display and ship auto-track application based on traditional paper chart and s-57 ENC. Aiming at this, some new techniques and algorithms including integrated spatial data management and display mode for ENC and paper chart, multi-scale data organization, embedded chart navigation method based on GPS are presented. And the integrated electronic chart pocket navigator system (PNS) based on PDA was developed.
