Tokugawa Japan Circuits Map, from CHGIS data

Tokugawa Data contains boundaries for Circuits (doo) and Provinces (kuni).

The boundaries were derived from several sources:

  • Japan Ministry of Land Infrastructure and Transport (historical map of the circuits) [MLIT]
  • UNEP / GRID prefecture boundaries GIS data [GRID]
  • DCW coastal boundary data [DCW]

The basic boundary was first determined from the MLIT data. The coast was snapped from DCW, and when possible the land boundaries were taken from the GRID data. In some cases the boundaries did not align with modern prefectures, and these were estimated and digitized by hand from a georeferenced image of the MLIT map.

DEM Images are included for use as topographic background maps. The images were processed from GTOPO-30 datasets, which have a resolution of 30 arc seconds (1 km) per pixel.
