![]() ![]() ![]() These inset maps provide a more detailed view of regional submarine cable hubs around the world. What is new for the 2022 Submarine Cable Map is that this year Telegeography has used a storymap format to help explain all this textual information in more detail.Īs you scroll through this year's version of the Submarine Cable Map the map pans and zooms to each of the smaller inset maps. Like last year's Submarine Cable Map this year's edition features lots of textual information, featuring both cable trivia and answers to FAQ's about cable suppliers and content providers. The new submarine cable map from Telegeography shows 486 cables and 1,306 landing stations. This includes all our telephone and Internet data. In the 21st Century submarine cables carry digital data. In the 19th Century the first submarine cables were laid to carry telegraphy traffic. Subsea cables carry telecommunication signals under the oceans, communicating information between different countries and regions of the world. Steve Song, telecommunications fellow at the Shuttleworth Foundation, maintains the African undersea cables map on his Many Possibilities blog.Every year the telecommunications company Telegeography releases a new map to visualize the updated global network of undersea telecommunication cables which carry all our data around the world.The 2022 Submarine Cable Map has now been published. Mahlknecht’s map is the second submarine cables map developed by an SA-based technologist. For now, Mahlknecht has created a feedback button and will make any proposed changes he receives manually. “Once the site has had some traffic and the inevitable bugs and inaccuracies have been ironed out, I’ll make the data available as a download,” he says. The data underlying the map - Mahlknecht uses a background from Microsoft’s Bing service - will be released under the General Public Licence, the same licence that governs the release of most open-source software. “I had to Google a lot and augment the Wikipedia data with a lot of information found in obscure documents all over the Internet.” I have an inherent mistrust of Wikipedia data,” he says. “Wikipedia has a ‘submarine communications cables’ category and I used this as a starting point before going to each cable’s homepage and gathering alternative information. Mahlknecht has drawn his data from a variety of sources. The width of the cables on the map reflect the relative design capacities of the systems. The new map clearly shows the huge volume of undersea capacity that will soon begin to serve African markets, especially along the continent’s west coast. “The Telegeography guys clearly have someone more skilled than me drawing the cables.” “I’m hoping someone more skilled in geographic information systems than me will see the map and offer to tidy up the routes,” he says. Submarine cable map free#Over time, with user contributions and guidance, Mahlknecht hopes his free cable map will eventually be more comprehensive and offer greater accuracy that the Telegeography map. I realised a free version needed to be made.” “I didn’t want it that badly and looked for a free alternative to print out but couldn’t find one. “I saw the Telegeography map and wanted one, but found it cost US$250,” he says. The map, which took Mahlknecht several months to complete, is free of charge and will remain so. Submarine cable map software#Durban-based software developer and occasional TechCentral columnist Greg Mahlknecht has built a free map showing the world’s submarine telecommunications cable systems. ![]()
