Description:

Abstract:

This dataset shows major bridges and causeways on Pohnpei. It was created by Island Research & Education Initiative (iREi) (2017), based on 2016 WorldView-3 satellite imagery by Digital Globe.

Purpose: To show the locations of bridges on Pohnpei.

Supplemental_Information:

The dataset is included the Digital Atlas of Micronesia, module Pohnpei, by Island Research & Education Initiative (iREi), in collaboration with Water and Environmental Research Institute of the Western Pacific (WERI) University of Guam and partial funding from United States Geological Survey (USGS), under WRRI 104-B Program, project # 2016GU302B.
