Stanford Geospatial CenterThis polygon shapefile is an index to the map series, '二百万分一大東亜航空圖 -- 1:2,000,000 Daitōa Kōkūzu.' This map series was originally produced by the Japanese Land Survey Department of the General Staff Headquarters [1943-1944]. 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/pt594sv3050engStanford Digital RepositoryPublicMilitary mapsTopographic mapsIndex mapsGrids (Cartography)Military1:2,000,000 Daitōa Kōkūzu, Maps Index 二百万分一大東亜航空圖DatasetsPacific Coast (Russia)Pacific Coast (North America)Pacific Coast (Asia)1943-1944Stanford
