Encompassing a broad range of history -- from the Greek and Roman eras to the Salem witch trials and the Dust Bowl of the early 20th century, leading scholars from the United States, Canada, and Great Britain analyze history with the tools of GIS. Through the use of modern GIS technology the past is revealed in new ways, in re-creating Civil War battlefields, by bringing ancient landscapes back to life, and in re-examining long-held assumptions about historical events. Combining a deep appreciation of the strengths of traditional history with the technology of GIS, this book provides a new perspective for historical researchers and GIS experts.
