Abstract—With the rapid development of nautical surveying and mapping and the growing of the mobile platform products, there is a growing demand for mobile electronic nautical chart information system. Traditional desktop electronic chart information system has played an important role in the field of hydrographic surveying and mapping. But it is very inconvenient to carry it offshore for maritime staff. We have developed the mobile electronic nautical chart information system based on IOS after deeply digging the demand of maritime staff for a mobile system. It realizes some traditional functions like the desktop system such as parsing and rendering of vector nautical chart file, integrated display of various kinds of map layers, data update and sharing inside the system and so on. Besides that, it also realizes some novel functions taking advantage of the characteristics of the mobile devices, such as trajectory recording and navigation, etc. This system is on trial in the relevant operational departments and reaches the level of operational application.

Index Terms—Nautical chart, information system, IOS, Objective-C++.
