Given a three parameter datum shift from WGS 84 to ED50 for this North Sea area is given as ¶dX = +84.87m, dY = +96.49m, dZ = +116.95m. ¶¶The WGS84 geographical coordinates convert to the following WGS 84 geocentric values using ¶the above formulas for X, Y, Z:¶¶   XA = 3771 793.97m¶   YA =   140 253.34m¶   ZA = 5124 304.35m¶¶Applying the given datum shifts to these, we obtain new geocentric values now related ¶to ED50:¶¶   XB = 3771 878.84m¶   YB =   140 349.83m¶   ZB = 5124 421.30m
