Cassini's 3D Globo Terrestre

Giovanni Cassini was an astronomer, mathematician and cartographer. In cartography he is probably most known for his family's Carte de France, the first ever topographic map of an an entire country. Started by Giovanni the Carte de France or the Cassini Maps were created by four generations of the Cassini family in the 18th and 19th centuries. The Cassini Maps were the first truly accurate national survey based on geodetic triangulation.

You can view all 182 pages of the Cassini Maps overlaid on top of Google Maps at the David Rumsey Historical Map Collection.

Giovanni Cassini also made globes. You can view a virtual 3d version of Cassini's 1790 Globo Terrestre on this Esri Old Globe map. The globe shows the routes of three of Captain James Cook's voyages. It also includes many of Cook's discoveries in the Pacific, including fairly accurate representations of New Zealand and Australia.

If you are interested in viewing more historical terrestrial globes then you might also enjoy the Virtual Globes Museum. This site includes 3d versions of the 1507 Waldseemüller globe, a number of Earth and celestial globes by the Dutch cartographer Willem Blaeu and globes by the Venetian Vincenzo Coronelli.

You can view 3d versions of Mercator's Earth Globe and Mercator's Celestial Globe on the University of Lausanne's website. Finally, you can view Miranda's World Map (1706) and Coronelli's Terrestial Globe using the State Library of New South Wales's Meridian application
