An anonymous reader writes "The Swiss Federal Office of Topography published a complete set of digitized historical maps from 1938 to 2011. The twist: a browser application allows you to create a time travel movie at any place in Switzerland for any zoom level. As an example, you can see the recession of Europe's biggest glacier in the last 75 years. The application is the most recent effort of the Swiss Government to make geodata freely available to the public at no cost using open source software and will include maps dating as far back as 1838."
