Type Shapefile
To show the approximate extent of municipalities of Yap.
This dataset shows the approximate lines separating the ten municipalities of Yap. The GIS file was created by Island Research & Education Initiative (2020) by georeferencing and digitizing the map printed in Sunn, Low, Tom and Hara, Inc. (1971) Feasibility studies for the installation of communal water facilities in the populated areas of Tomil, Gagil and Kanifay, Honolulu, Hawaii, 24 p., and slightly modifying it based on village locations shown in the USGS topographic map and village municipal affiliations listed in the Yapese-English dictionary. Note that the sources used are not authoritative and the boundaries shown are highly approximate and in no way definite. This map does not constitute any sort of recommendation, claim, or endorsement.

The dataset is included in the Digital Atlas of Micronesia, module Yap, 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.
