The map, at a scale of 1:2,000,000, covers Hokkaido and includes estimated coal reserves, reflecting the Meiji government&#8217;s emphasis on resource development. Geological maps represent the relationships between geological strata and rocks on topographic maps. Experts emphasize that &#8220;geological maps and related materials come in a wide variety of types, and various types of information are now available online.
