Study on quickly producing Notice to Mariners based on SQL Server

Compared with the digital production of nautical chart (i.e., chart), nowadays we almost compile Notice to Mariners by hand. It is apparent that how to quickly produce Notice to Mariners by digital technique is very necessary and urgent now. Consequently, the key techniques of quickly producing Notice to Mariners based on SQL Server, such as creating database of Notice to Mariners, designing electronic charts for reference (i.e., a kind of chart which is used as an assistant to compile Notice to Mariners and record the correction information of Notice to Mariners), developing Notice to Mariners production software, are discussed in this paper. The application shows that the method can integrate and optimize the traditional manual procedure, and improve the produce efficiency and the chart quality evidently.
