Description:
Abstract:
This dataset shows the communication infrastructure on Pohnpei. The original data, so-called Digital Line Graphs (DLSs), were created by U.S. Geological Survey (USGS) for the 1:25,000-scale topographic maps (2001). The dataset was updated by Pacific Disaster Center (PDC) (2014) and Island Research & Education Initiative (2017) based on information provided by FSM Telecommunications Corporation.
Purpose: To show the communication infrastructure 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 of DLGs 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.
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:
Not known. However, based on the accuracy of other DLG data, communications and cellular towers could be up to 50 meters off. Wifi access points and cell sites are believed to be more accurate.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Explanation: Visual comparison with WorldView-3 satellite imagery.

Source_Contribution:
A shapefile named crit_fac_bldgs_pni_utmz57.shp (derived from the DLGs) was obtained by the Island Research & Education Initiative (iREi) as part of a data collection effort over many years and from a variety of sources. Many of the original sources are unknown due to incomplete or missing metadata, but mostly include NGOs and state and national government agencies in the FSM. This particular layer was most likely created by the Pohnpei State Government. The dataset was obtained by iREi prior to 2012.
