This map of Asia is from the mid-19th century ‘Grosser Atlas der Erde [Great Atlas of the Earth]’ by the German publisher Albrecht Platt. It shows part of Southeast Asia, including the region’s borders with India and China.

This title of this map refers to orography (which is shown in the use of hachures, short lines/dashes that give a sense of the shape and steepness of terrain) and hydrography (which is shown in the highlighting of coastal regions, shoals and reefs).

Hand-drawn portolan (nautical) chart, featuring a rhumbline network (the web of interconnected lines), bathymetry (sea depth), shoals and reefs, names of coastal settlements, and an elevation (side view) of a mountain at the north tip of Borneo.
