Electronic marine chart is playing an increasingly important role in current marine navigation and positioning. This paper focuses on the study of related techniques in electronic marine chart display process, reads and displays electronic marine chart of Shapefile format, renders electronic maps according to S -52 international standards, realizes accurate positioning through the conver- sion of horizontal coordinates into geographical coordinates using Mercato projection plane, converts Shapefile attribute data into Geo- database to increase display speed of marine map. The display effect and function of electronic marine map shows that this study is of high practical value and wide application prospect.
