The Application of GIS in Historical Geography
The increasingly developing GIS technologies challenge the historical geography which is short of quantitative proxies, and challenge the historical maps because the spatial and temporal coverage of historical maps is not high and the contents of historical map can not reflect historical change. China Historical GIS (CHGIS), investigation of Chinese environment in the past 2000 years, and the development of provincial historical geography information system for a given dynasty have been initiated. GIS is being applied to historical geography research. CHGIS is in the fundamental period and has lots of work to be implemented.
