Japan Prefecture Map Puzzle Pieces 1 /3

thingiverse

Japanese maps comprising every single prefecture. Each prefecture is represented on these maps. They are scaled 1/440000 vertically, 1/3052500 horizontally. The elevation data used were calculated from satellite observations by JAXA's artificial satellites. I employed a makeshift method to convert longitude and latitude into X-Y plane coordinates, which likely introduces some error into the shapes and sizes of these prefectures.
