Gaihozu meaning “maps of outer lands” is the maps of areas outside the Japanese Islands made by former Japanese Imperial Army before the end of the World War II. Despite the fact that these maps were prepared for military purpose, they contain the valuable records of detailed landscapes including landuse and landcover in the past. This site was designed with ArcGIS Online technology to interactively view about 680 geo-referenced maps in Indonesian territory from the collection of Gaihozu at Tohoku University.
Clicking a shaded box on the index map enable you to show the corresponding geo-referenced map in 3D scene with its metadata, such as map scale and printed year. Clicking a button of ratio like 1:500,000 switched the index map of the corresponding map scale.
