To show the road network on Chuuk.
This map shows the road network on the islands in Chuuk Lagoon. It only includes major roads. The dataset was created by Island Research & Education Initiative (iREi) (2020), by extracting data from the Open Street Map (2020) and formatting it for use in this atlas

There are no expressed warranties associated with the release of this dataset. Specifically, no warranty is made that the GIS data or any subsequent updates will be error free and no warranty is made regarding the positional or thematic accuracy of the GIS data. The GIS data and any features it depicts do not represent or confer any legal rights, privileges, benefits, boundaries or claims of any kind.
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. Topology has been checked during the latest update (2017).
Features are believed to be complete based on visual comparison with the source imagery.
The classification type and names may need to be updated as attributes have not been updated consistently or field verified.
The horizontal accuracy has not been assessed but is assumed to be within 5-10 meters of the source imagery.
