![]() 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. 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. Interactive submarine cable map from TeleGeography.Durban-based software developer and occasional TechCentral columnist Greg Mahlknecht has built a free map showing the world’s submarine telecommunications cable systems. Users can also return a filtered list of cable lines by year by typing in “ready for service” and selecting the year of interest. Users can click on individual cable links to see the submarine cable name, owners, and landing points. This online map is updated regularly and pulls data from the company’s Global Bandwidth Research Service. Submarine cable map from TeleGeography.įor a more interactive version, TeleGeography also has an interactive Submarine Cable Map. Those interested in a printed version can buy a wall-sized map (36” x 50”) for $250. TeleGeography has placed the map online as a browse able version or as a larger image. The global cable map also includes several infographics including: causes of cable faults, 2008-2011, number of cable breaks by country, 2008-2012, and mean time to commence repair by country, 2008-2012. An inset topography map shows geographically accurate submarine cable paths and the locations of seven cable maintenance agreement zones. The main map also highlights details about key cable landing stations in Hawaii, Southern Florida, New York, New Jersey, Cornwall, Singapore, Hong Kong, Tokyo, and Sydney. The countries are color-coded to show how many international cable systems are connected to that destination. ![]() The world map shows 263 in-service and 22 planned undersea cables. This network of criss-crossed cabling enables the world to stay connected. Fiber optic cable crosses the world’s ocean floors, serving as the backbone of the Internet. The map shows 285 cable systems current in existence or due online by 2015 around the world. TeleGeography, a telecom data company, has released the 2014 version of its Submarine Cable Map. ![]()
