The Subsea Data Cable Security Map – Fusing Public Information for Enhanced Critical Maritime Infrastructure Security

This work presents a mapping tool designed to visualize potential risk factors affecting the lifelines of intercontinental communication – subsea data cables. While various geographic information systems provide public data on the oceans, including browser-based maps showcasing maritime fixed infrastructure, these services vary widely in terms of data granularity and functionality. A comparison of different platforms highlights this diversity, with existing maps of subsea infrastructure serving different purposes. However, the absence of an online map tailored specifically to the security needs of critical subsea infrastructure prompted the development of a new mapping solution. The Subsea Data Cable Security Map aims to integrate and display available data on submarine cables and associated risk factors, with a strong focus on usability, modularity, and ease of maintenance.
