Stanford Geospatial CenterThis polygon shapefile is an index to the map series "百万分一航空圖素圖 漢口 - 成都 -- 1:1,000,000 Kōkūsozu_Kankō - Seito" (1942). Stanford University Libraries holds a large collection of Japanese military and imperial maps, referred to as gaihōzu, or "maps of outer lands." These maps were produced starting in the early Meiji (1868-1912) era and the end of World War II by the Land Survey Department of the General Staff Headquarters, the former Japanese Army. The Library is in the process of scanning and making available all of the maps in the collection.This layer provides an index map that can be used to locate individual scanned map sheets.Shapefilehttps://purl.stanford.edu/km637dq7307engStanford Digital RepositoryPublicTopographic mapsIndex mapsGrids (Cartography)Military mapsMilitaryBoundaries1:1,000,000 Kōkūsozu_Kankō - Seito, Maps Index 百万分一航空圖素圖 漢口 - 成都DatasetsChengdu (China)Hankou (China)1942Stanford
