Interactive Submarine Cables Map by ESRI January 4, 2018 Dave Ohara We have all seen submarine cable maps. What is nice is ESRI has one that is a live map. The link is here. You can review the cables based on year, cables, or landing points. Why We Love ItDeep on the ocean floor you will find communication cables made to carry signals from one land to another. The first undersea communications cables, laid in the 1850s, carried telegraphy. Now these cables carry our phone and Internet traffic. Yet, they remain relatively hidden in the depths of the ocean. We love how this map lets us explore global cable connections. We can see the cables all at once or focus on interdependencies by using the contents pane to filter by construction year, a specific cable, or a landing point.Why It WorksWhen we view undersea cable data on a global scene view, we get a real sense of how these cables tie together the world’s populated places. This map uses spheres and tubes to symbolize the landing points and cables. This works to emphasize connectivity while remaining playful and easy to understand. When you filter information based on a single cable, landing point, or construction year, you can see interdependencies that are otherwise less obvious. This map does not rely on traditional pop-ups when you select a feature, but instead hides all unrelated features.
