analysis: The text discusses the importance of hydrographic surveying and nautical charting for the safety of navigation, particularly in coastal areas where there are large exclusive economic zones and extensive maritime trade. It highlights the lack of adequate surveying and charting capabilities in many coastal states, which poses a significant risk to navigation and trade. The text also emphasizes the need for a long-term plan to train personnel and utilize technology for hydrographic and charting operations.
