This map uses a variety of methods to aid navigation, including a rhumbline network (a web of lines to help plot routes). The numbers on the sea surface indicate depth (bathymetry), and the drawings of mountains (elevations) were used as landmarks.

Notes on this map describe European colonial territories and trade with Asia, though this is concentrated around India, and mostly has not yet reached further east to ‘India extra Gangem [India beyond the Ganges]’ as Southeast Asia is labelled.
