APRGP GPS Campaign 2017: Asia-Pacific Geodetic Positioning Analysis

The Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an annual activity coordinated by the UN-GGIM-AP Geodetic Reference Frame Working Group. This document provides an overview of the data analysis from the 2017 campaign, which estimates station coordinates in the International Terrestrial Reference Frame (ITRF). The data is contributed by member country agencies and is used to densify the ITRF in the Asia Pacific region for scientific research and local applications.

Use Cases

• Densifying the International Terrestrial Reference Frame (ITRF) in the Asia Pacific region based on the described GPS data contributions.
• Supporting local scientific research and applications requiring geodetic positioning data as mentioned in the description.
• Analyzing regional tectonic plate motion or crustal deformation using the derived station coordinate estimates.
• Facilitating regional cooperation in geodesy amongst national agencies as a stated role of the Working Group.

Strengths

• Data is contributed by multiple national agencies across the Asia Pacific region, suggesting a collaborative and regionally representative source.
• Results are supplied to the official ITRF product centre, indicating alignment with an international geodetic standard.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary file format is PDF, which may not be directly machine-readable for analysis.
