A late 18th century map of Asia published in London by John Bowles, with regions indicated by colour. Central Borneo is labelled ‘Part inhabited by the Biayos’, which is seen on many contemporary maps, often with the comment ‘a savage people’.

Nautical charts like this are detailed around the coasts and on the seas (e.g. river mouths, islands, shoals and reefs) while the interiors are blank. The web of lines is a rhumbline network, while the numbers indicate sea depth (bathymetry).

Maritime routes had to be adjusted in response to the changing monsoon seasons, as is seen on this late 18th century map of the Indian Ocean. Drawings of the heads of children blowing—called ‘wind-heads’—are used to indicate wind direction.

Navigation chart of the Sunda Strait, showing bathymetry (sea depth), shoals and reefs, landmarks, and a rhumbline network. Notes record good anchorages, sources of water and supplies etc. Inset map of the Zutphen Islands off the coast of Sumatra.

A map of the China Sea between Malaya, Sumatra and Borneo. The numbers indicate sea depth (bathymetry), and there are drawings of the side views of some of the islands (elevations), both used to aid navigation. Some maritime routes are also marked.

This late 18th century map features a number of labels describing the local populations, including the Kemoys ('Savage People') of the mountains of Cokin China (Vietnam), the Biayos of Borneo, and the 'Wild People' of the mountains of Pegu (Myanmar).
