Urbano Monte's Planisphere As a Globe

In November 2017 the David Rumsey Map Collection at Stanford University obtained one of only two manuscript copies of Urbano Monte's Planisphere. This huge map is one of the earliest large complete maps of the world.

The original manuscript map is in the form of a 60 sheet atlas. Urbano Monte intended for the sheets to be joined together to create one very large 10 foot map. The David Rumsey Map Collection has achieved that goal by digitizing all 60 sheets and creating a digital interactive map of Urbano Monte's Planisphere.

Jeremy Ashkenas has used the David Rumsey Map Collection's version of Urbano Monte's 1587 map to create an interactive 3D WebGL globe of the Planisphere. Urbano Monti’s Planisphere (1587) allows you to view the map as an interactive globe.

Urbano Monte's original Planisphere uses a north polar azimuthal projection. This projection places the North Pole at the center of the map. Urbano Monte himself suggested that a central pivot be added to the center of the map so that users could rotate the map while exploring the atlas. Viewing the map as a 3D digital globe also seems to work.

Visionscarto has also used the map tiles from the David Rumsey interactive map to create a tool for viewing Urbano Monte's Planisphere using different map projections. Urbano Monte World Map Reprojections. includes 21 different map projections. It even includes everyone's favorite Mercator projection, which means you can make direct comparisons between Urbano Monte's Planisphere and Google Maps if you so wish.
