A map of the administrative divisions of Sumatra and the Malay Peninsula. The mountains of western Sumatra and the central Malay Peninsula are represented by hachures: short lines/dashes that give a sense of the shape and steepness of terrain.

Based on surveys by Sir Stamford Raffles, this German map of Sumatra focuses on the navigation of coasts and straits, with bathymetry (sea depth), anchor points, shoals and reefs marked, including on inset maps of Singapore and the Bangka Strait.
