In collaboration with CHGIS, the Russian Academy of Science, Institute of Geography in Moscow is cataloging and digitizing important historical maps that were produced by Russian cartographers in the late 19th and early 20th centuries. The results will be provided free for academic use in several ways:

1. in the form of a catalog of all the maps found in the Russian archives that relate to China, including maps in Russian and other European languages
2. in the form of GIS datasets, which contain point features extracted from selected maps
3. in the form of searchable records integrated into the CHGIS search engine
