ED50 / 3-degree Gauss-Kruger zone 9

Available transformations
to EPSG:4326

Selected transformation

Method: NTv2

Grid Files: SPED2ETV2.gsb

Remarks: Parameter values from ED50 to ETRS89 (12) (code 15932). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaces ED50 to WGS 84 (40) - see supersession record.
