This 20m Topographic Map is included in version 1.2 as well as version 2.0 Japan 1:25000 Map.

20m Topographic map

Topographic map included in our map is generated from the 2 arc second (50 meter) mesh of elevation on the Digital Map 50m Grid (Elevation) published by Japanese Geographical Survey Institute (Kokudo Chiri-in). Although we use quite decent algorithm of generating contour lines, it is not a real trace of topographic map. Therefore, we cannot guarantee the accuracy of the contour line. We do expect there may be incorrect as well as non-real lines. Please understand this limitation when you use.
