Keywords: nautical chart; paper chart; digital chart; integrative update; model and technique The actuality of the updating technique in China Based on our research, we find that, the chart updating technique in China is behindhand, which is not suitable to the advanced production mode of chart now. Tow kind of chart product are provided now a day in China, and they are the traditional paper chart and all kinds of digital chart. So far, the data for updating digital chart
