Summary

To show the locations of principal passes in the barrier reef around Kosrae.

Description

This dataset shows the locations of principal passes in the barrier reef around Kosrae. It wasderivedby Island Research & Education Initiative (iREi) (2019) by slightly modifying data from U.S. Geological Survey 1:25,000-scale topographic maps (2001). The place names shown on this map are copied from the sourcerequire thorough verification and correction of spellings to conform with Kosraean orthography.
