Chinese Civilization in Time and Space

This system consists of three major components: basic
geospatial materials, WebGIS integrated application
environment, and thematic information. The fundamental base
maps are based on Dr. Tan's \The Historical Atlas of China\.
\The Historical Atlas of China\ provides users with Chinese
historical features, covering Chinese history over the past
2000 years, from the ancient time to Qing dynasty.
Furthermore, various historical atlas and remote sensing
imagery are persistently geo-referenced and overlaid into
the system to broaden the spatial and temporal scope.
