Operation method formula

H(II)=H(I)+a1+a2·Mo·(LAT-LATo)+a3·No·(LON-LONo)·cos(LAT) 

H(I): height in the source system [m]
H(II): height in the target system [m]
Mo: radius of curvature in the meridian of GRS80 [m] in Po
No: radius of curvature perpendicular to the meridian of 
GRS80 [m] in Po 
LAT: latitude in ETRS89 [radian]
LON: longitude in ETRS89 [radian]
Po(LATo,LONo): Reference point of the transformation

a1...vertical translation [m]
a2...slope in the direction of the meridian [radian]
a3...slope in the direction perpendicular to the meridian 
[radian] 
Operation method parameters number3
Operation method remarks
coordinates of the reference point Po:
 Lat = 52°32' N
 Lon = 13°10' E
Operation parameter namevertical translation
Operation parameter value+0.157 m
Operation parameter remarks
Operation parameter nameslope in the direction of the meridian (positive when up northwards)
Operation parameter value+0.007"
Operation parameter remarksEquivalent to +0.004 m height change at a distance of 100 km of Po. To be in agreement with formulas the slope parameter has to be converted to Radians.
Operation parameter nameslope in the direction perpendicular to the meridian (positive when up eastwards)
Operation parameter value+0.005"
Operation parameter remarksEquivalent to +0.003 m height change at a distance of 100 km of Po. To be in agreement with formulas the slope parameter has to be converted to Radians.
