Historical Geographic Information System for China


Dataset Abstract/Summary

When complete, the China in Time and Space (CITAS) historical Geographic Information System (GIS) will cover changes in China over the past 1,250 years. Spatial data will include the boundaries of administrative units, configuration of the hydrologic system, location of central places, and networks of transportation. Attribute data will include population (including ethnic, cultural, linguistic, and religious composition), finance, migration, land cover, and land use. Currently, this GIS is under construction but intermediate products should be ready for release by the end of 1994. Additional dataset information will then be made available.
