Transform Coordinates
Remarks
Parameter values derived from differences in CTs to ITRF2020 (codes 9999 and 10100). These supersede all values published in past IERS/ITRF documentation (CT code 9023). Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9.
Frequently Asked Questions
How do I convert ITRF91 to ITRF92 coordinates?
Use the coordinate transformation tool above to convert ITRF91 (EPSG:4913) to ITRF92 (EPSG:4914). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geocentric domain) method with 0.005m accuracy.
How do I transform ITRF91 to ITRF92 using Proj4js?
Use proj4.defs to define both EPSG:4913 and EPSG:4914, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the ITRF91 to ITRF92 transformation?
This transformation (EPSG:10142) has an accuracy of 0.005m using the Position Vector transformation (geocentric domain) method. Area of use: World.
