To show the municipalities of Kosrae pre-1980s.
This dataset shows the four municipalities of Kosrae plus the fifth municipality, Walung, before it was merged with Tafunsak in the 1980s. The original data, so-called Digital Line Graphs (DLSs), were created by U.S. Geological Survey (USGS) for the 1:25,000-scale topographic maps (2001). The data were modified by Island Research & Education Initiative (iREi) (2019) to fit the most recent base layer. Note that boundaries shown in this map are not definite. This map does not constitute any sort of recommendation, claim, or endorsement.

The dataset is included in the Digital Atlas of Micronesia, module Kosrae, by Island Research & Education Initiative (iREi) in collaboration with Water and Environmental Research Institute of the Western Pacific (WERI) at the University of Guam and funding from United States Geological Survey (USGS) under WRRI 104-B Program and FSM Department of Environment, Climate Change & Emergency Management (DECEM).

Topological requirements include the following: lines must begin and end at nodes, lines must connect to each other at nodes, lines do not extend through nodes, left and right areas are defined for each line element and are consistent throughout the file, and lines representing the limits of the file (neatline) are free of gaps.
The completeness of the data is unknown but should be consistent with the level of information normally shown on U.S. Geological Survey 1:24,000-scale topographic maps.
Attribute accuracy is tested by manual comparison of the source with hard copy plots and/or symbolized display of the digital line graph on an interactive computer graphic system. Through inspection and queries, attempts were made to ensure completeness and consistency of attribute values.
The names of the municipality/ wehi were updated using standard spellings according to municipal constitutions and Kosraean orthography.
