APRGP GPS Campaign 2017: Asia Pacific Geodetic Positioning Data

GPS data from the 2017 Asia Pacific Regional Geodetic Project (APRGP) campaign, contributed by member agencies of the UN-GGIM-AP Regional Committee. The composite dataset was analyzed by the Geodetic Reference Frame Working Group to estimate station coordinates in the International Terrestrial Reference Frame (ITRF). Results are used to densify the ITRF in the Asia Pacific region and support local and global scientific research.

Use Cases

• Estimating precise station coordinates based on GPS data contributed by member countries.
• Densifying the International Terrestrial Reference Frame (ITRF) based on regional GPS campaign results.
• Supporting local geodetic applications based on the regional geodetic infrastructure.
• Enabling scientific research based on the composite GPS dataset from the Asia Pacific region.

Strengths

• Data is collected through an annual, coordinated campaign by a United Nations regional committee working group.
• Results are supplied to the official ITRF product center, indicating a level of quality assurance.
• The dataset is intended to support both local applications and global scientific research.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is PDF, which may not be readily machine-readable for analysis.
