According to the needs of ENC(Electronic Nautical Chart) data in the navigational assessment, this paper analyzes the source of ENC data, such as S-57 data, MVCF(Military Vector Chart Format) data and CAD(Computer Aided Design) data. An effective method of ENC data generation has been developed. Special techniques are investigated for generating ENC data, such as ENC data structure designing, chart data conversion, digitization method of raster images of CAD design drawing, optimization approaches and data integration methods. Software has been developed to edit the chart data with good performance. The technologies developed in this paper have been applied to more than 100 practical projects and successful results have been obtained. %@ 2083-6473
