Description:
Abstract:
This dataset shows the rivers and streams on Pohnpei as represented on the U.S. Geological Survey (USGS) 1:25,000-scale topographic maps (2001). The data set was extracted from the Digital Line Graphs (DLGs) from USGS and names from the Geographic Names Information System (GNIS) by Island Research & Education Initiative (iREi) (2017) and slightly modified to match the (partially) updated shoreline.
Purpose: To show the rivers and streams 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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
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.
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.
Completeness_Report:
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.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The updated sections (mainly around Kolonia and Sokehs) are accurate within a few meters, the other areas are accurate within about 20-30 meters.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Explanation: Visual comparison with WorldView-3 satellite imagery.
