Summary
Abstract: Think Quest's Historical GIS provides multiple data sets covering the last 4000
years of history. In addition, we have provided a variety of internet
applications of these data, including static images, flash animations, and
interactive applications. The data is not very accurate in terms of absolute
position, as it is only intended to demonstrate relative positions of nations
in history.

Purpose: The site is intended for educational use. While it is on a server intended for
contest entries, we are continuing to maintain the site even after the contest
has ended. The data may be used as a reference to anybody interested in GIS,
though it is lacking detail. This data originates from a basic dataset provided
by ESRI. As it progresses further into history, the quality/accuracy of the
national borders depicted greatly degrades.
