This paper is concerned with the implementation of nautical international (INT) charts and Electronic Navigational Charts (ENCs) schemes in the Mediterranean region. It documents the necessity to respect coastal statesʼ cartographic competences in accordance with international law of the sea, but at the same time, it focuses on the need for fruitful cooperation between states with opposite or adjacent coasts. Reminding the main international conventions to protect the freedom of navigation, to regulate maritime spaces and to safeguard the human life at sea, the paper delves into the technical specifications for nautical charting issued by the International Hydrographic Organization (IHO). Through three case studies in the Mediterranean Sea, it highlights how the hydro-cartographic cooperation may represent a means through which coastal states can play a considerable role from a cartographic perspective, making a noticeable contribution not only to navigation safety, but more generally to establishing mutual collaboration relationships, with win-win solutions for both end users and charts producers. The paper ends with some considerations about the future of nautical charts and an overview of the S-100 data framework that will require, even more, the close partnership among many maritime stakeholders.

本文关注地中海地区国际航海图 (INT) 和电子航海图 (ENC) 计划的实施。它记录了根据国际海洋法尊重沿海国制图能力的必要性，但同时也强调了相向或相邻海岸国家之间开展富有成效的合作的必要性。提醒保护航行自由、规范海洋空间和保障海上人类生命的主要国际公约，该论文深入研究了国际航道测量组织（IHO）发布的海图技术规范。通过地中海的三个案例研究，它强调了水文制图合作如何作为一种手段，使沿海国可以从制图角度发挥重要作用，不仅对航行安全做出显着贡献，而且更广泛地通过双赢解决方案建立相互协作关系对于最终用户和图表制作者。本文最后对海图的未来进行了一些考虑，并概述了 S-100 数据框架，这将需要更多海事利益相关者之间的密切合作。
