TeleGeography's submarine cable map is based on our authoritative Global Bandwidth research and depicts international active and planned submarine cable systems and their landing stations. The map presents data about each cable, including landing points, owners, length, ready-for-service (RFS) date, and website. Try it today! Visit http://www.submarinecablemap.com.

TeleGeography draws the cable routes and plots the landing points with Adobe Illustrator. Using Avenza's MAPublisher plug-in, which works with Illustrator, two sets of data are exported as KML files: the cable routes (as MultiLineStrings) and landing points (as Points). These KML files are then parsed to create CSV files that are uploaded to Google Fusion Tables.
We use Google's Maps API v3. to transform the Google Fusion Tables into two separate map layers of cable routes and landing points. The interactivity on the map is driven by javascript and was written in-house at TeleGeography.
This interactive map Javascript was created using the Node.js utility CoffeeScript written by Jeremy Ashkenas, the Ember web application framework, the HTML5 Boilerplate front-end template, the node-build-script and node-ember-precompile tools. The CoffeScript for the map was written in-house at TeleGeography.
Notable Commandline examples:
# Install ember-precomile from github to get versions correct.
npm install --from-git git://github.com/gabrielgrant/node-ember-precompile.git
# precompile handlebars templates
ember-precompile handlebars/*.handlebars -f src/javascripts/handlebars.tmpl.js
# Used watchr to compile coffeescript/handlebars.
watchr bin/script.watchr
# Watch, server and build using h5bp, very helpful
