Historical maps

How to superimpose the past over the present and see both simultaneously ?

Quite simple with GeoGarage spatial image web server :

  • World Globe 1790 : this globe shows contemporary discoveries in the Pacific as well as the routes of three of Captain James Cook's voyages...
  • San Francisco 1859, one of th earliest maps of San Francisco Bay by the U.S. Coast Survey...
  • nautical chart of Cuba (1775), showing ship tracks, rhumb lines, currents, depths by soundings...
Click on rumsey.geogarage.com to get access to 120 ancient maps from David Rumsey collection.
And don't forget to play with the transparent map slider option, it just gets better !
