Method: Position Vector transformation (geog2D domain)
Remarks: Parameter values from ED87 to ETRS89 (1) (tfm code 4078), assuming that ED50 is identical to ED87 and ETRS89 to WGS 84. Errors caused by this assumption can reach 3-5m. Used by NAM for offshore operations until mid 2004, then replaced by tfm code 1311.
