Frequently Asked Questions
How do I convert Karbala 1979 to IGRS coordinates?
Use the coordinate transformation tool above to convert Karbala 1979 (EPSG:4743) to IGRS (EPSG:3889). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 0.3m accuracy.
How do I transform Karbala 1979 to IGRS using Proj4js?
Use proj4.defs to define both EPSG:4743 and EPSG:3889, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Karbala 1979 to IGRS transformation?
This transformation (EPSG:5077) has an accuracy of 0.3m using the Geocentric translations (geog2D domain) method. Area of use: Iraq - onshore.
