This is one of the typical navigation charts used in the Marshall Islands until the mid-20th century, when new technologies and navigation models were introduced to the country. The patterns represent important themes for canoe navigation, such as ocean swells, courses to follow, and existing islands.

The location of the islands was usually represented by shells, as can be seen on this map, although it could also be simply by crossing two existing lines. Each of the lines represented the course of navigation, which could vary from person to person, so it was common for each of these maps to be used by only one individual.

This map highlights a completely different way of understanding cartography, strongly influenced by the needs of the Marshallese to move between islands.
