CHGIS China Taihu District County Boundaries, 1820
- Polygons represent the counties in the Taihu region of China, (ten prefectures around Taihu Lake,) for the year 1820. The CHGIS will establish a database of historical administrative units, as well as physical and cultural features for different periods in Chinese History, and will also provide a base GIS platform for researchers to use for spatial analysis, temporal statistical modeling, and representation of selected historical units as digital maps.
