In the few short years since it became freely available, Google Earth has become commonly used to explore the earth’s surface, to navigate geographic paths, to locate points of interest, and to store and serve terabytes of geographic information.
Google Earth is a free Virtual Globe or Geobrowser that allows you to display images of the earth on a globe and provides the illusion of manipulating a three-dimensional globe on-screen.
Emmanuel Kreike, Associate Professor of History at Princeton, combines models and methodologies from the humanities and social sciences with approaches from environmental science and forestry to analyze how ecological, political, social, cultural, and economic processes affect the use and management of natural resources in past and present southern Africa.
To study the past and the sweeps of environmental change, Africanists and indeed, many humanists and scientists have conventionally relied upon written archival records as well as oral histories, the individual perspectives of elders or oral traditions that have been handed down through the generations. The nature of the existing data made it difficult or impossible for researchers in any field to establish a link to the physical reality or even to draw meaningful conclusions about the complex processes of environmental change. Oral histories, for example, often tell us more about the present than the conditions in the past.
