Transformation derived by inversion of seven site velocities within the transformation coverage area. Transformation accuracy at 2σ is 0.15 m between 1994.0 and 2035.0 for locations within Papuan Foreland. Transformation precision degrades in plate margin deforming zone (PFTB) near plate boundary with NGH and Woodlark plates. Transformation not valid outside stated extent.

Frequently asked questions

How accurate is converting ITRF2020 to PNG94?: The most accurate official EPSG transformation between these systems is accurate to about ±0.15 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?: No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
