This is a data set of elevation in which the grid was derived from Standard Grid Squares (Third Area Partitions with a side of about 1km) by subdividing each square into a 10 × 10 grid with a mesh size of 100 m × 100 m. This data was based on Fundamental Geospatial Data (DEM) 10 m Mesh (Elevation) by Geospatial Information Authority of Japan. Average elevation in a 100 m × 100 m grid was defined as an attribution of the grid.

Publicly available data collected from the website of the relevant organizations and converted into CSV, XML, and KML formats that were easy to use.
