Description:
Abstract:
This dataset shows the road network on Pohnpei. It includes major roads as well as smaller paved and unpaved roads. The data set was originally created by U.S. Geological Survey (USGS) (2001) for Digital Line Graphs (DLGs) to show information on 1:25,000-scale topographic maps. It has been modified to reflect changes and add street names of selected roads throughout the years by various government organizations including Kolonia Town Government, U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS), and Pohnpei State Government - Department of Land and Natural Resources (2013). A major update was performed by Island Research & Education Initiative (iREi) (2017) to reflect changes based on 2016 WorldView-3 satellite imagery by Digital Globe. The attribute information (name and type of road) has not been updated recently.
Purpose: To show the road network on Pohnpei.
Supplemental_Information:
The dataset is included in the Digital Atlas of Micronesia, module Pohnpei, created 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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The classification type and names may need to be updated as attributes have not been updated consistently or field verified.
Logical_Consistency_Report:
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).
Completeness_Report:
Features are believed to be complete based on visual comparison with the source imagery.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy has not been assessed but is assumed to be within 5-10 meters of the source imagery.
