Reading Historical Maps Digitally: How Spatial Technologies Can Enable Close, Distant and Dynamic Interpretations

David Rumsey gave the opening keynote lecture for the Digital Humanities 2011 Conference at Stanford University on June 19, 2011.

Abstract of the talk: Maps are dense, complex information systems arranged spatially. While they share similarities with other visual artifacts, their uniqueness as spatially arranged visual information both allows for and demands special digital approaches to understand and reuse their content. Georeferencing, vectorization, virtual reality, image databases, and GIS-related tools all work to unite our eyes, minds, and computers in new ways that can make historical maps more valuable and accessible to humanists concerned with place and space over time. Rumsey will explore the tools and techniques that have implications for the ways digital humanists approach visual information.

Cassini Terrestrial Globe and GIS Layers

In this video the 1790 Cassini Terrestrial Globe is combined in ESRI's ArcGlobe with other GIS layers, including NASA's satellite image of the world at night, several satellite images of world topography and bathymetry, and other historical maps and globes.

Cassini Terrestrial and Celestial Globes 1790 video

Giovanni Maria Cassini made a Terrestrial Globe in 1790 and a Celestial Globe in 1792.  This video shows both globes virtually recreated in Google Earth, with the Celestial Globe turned inside out and placed 64 million meters outside the Terrestrial Globe.  The same space can be viewed live in Google Earth  (plugin required, turn off Atmosphere layer in Google Earth).
