Remarks

Defines DB_REF so considered errorless. Defined with parameter values for forward and reverse CTs with rotation and scale to greater resolution. The OGP truncated values and reversible formula have no impact on calculation results at the micron level.

Frequently Asked Questions

How do I convert DB_REF to ETRS89 coordinates?

Use the coordinate transformation tool above to convert DB_REF (EPSG:5681) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 0m accuracy.

How do I transform DB_REF to ETRS89 using Proj4js?

Use proj4.defs to define both EPSG:5681 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the DB_REF to ETRS89 transformation?

This is an exact transformation (EPSG:5826) with no loss of precision (0m accuracy) using the Coordinate Frame rotation (geog2D domain) method. Area of use: Germany - onshore.
