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/vy566dn2202engStanford Digital RepositoryPublicTopographic mapsIndex mapsGrids (Cartography)Military mapsMilitaryBoundariesKimitsu kaizu_Suirobu hi | 海軍航空圖 Kaigun Kōkūzu, Maps Index 機密海圖 水路部秘DatasetsTaiwanLiaoning (China)Shandong (China)Shanghai (China)Japan1936-1944Stanford
