From Historical Cartography to Mapping the World in the 21st Century - San Francisco Bay Events

▻http://franciscobay.events/san-francisco-from-historical-cartography-to-mapping-the/99711

Re-imagine the globe and cultural exchange through the lens of the Ricci and Verbiest maps.

Hear about the history of cartography and contemporary issues related to mapping, with a focus on the latest technological innovations pioneered by Google and NASA. Join Dr. Laura Hostetler, EDS-Stewart Chair at USF’s Ricci Institute, as she delves into the complex geopolitical controversies surrounding territorial mapping. Dr. Ralph Ehrenberg, Head of the Geography and Map Division of the Library of Congress, will speak on its important collection of East Asian maps, including the Verbiest map featured in the exhibition. Former NASA administrator Stephen Sandford and Google Geospatial Programs coordinator Ed Parsons will provide insight into the technologies that power the mapping processes of the 21st century and describe the evolution, over centuries, of the way we view the world.

This is a perfect pairing with our spring show, “China at the Center: Rare Ricci and Verbiest Maps.” See it before it closes, May 8.

Abstract: This paper is meant to be the beginning of a project that examines the use of abstract mathematics and the changing ontology of mapmaking in the early years of the development of computer cartography. The history of the conceptual developments that took place during this revolutionary period in the history of mapmaking is both controversial and incomplete. Much of the primary source material has yet to be examined by historians, residing as it does in obscure journals, government archives and in obsolete software. This study provides a look at one example of this conceptual development in the early years of computer cartography through a close reading of two papers on existence theorems published by the Harvard Laboratory for Computer Graphics and Spatial Analysis. It attempts to highlight the changing conceptual and mathematical foundations of mapmaking during this period and in doing so provides a case study for the difficulties that historians of modern cartography face in researching this critical period in its history.
