ORMT realization example

• North American 1927 (NAD 27)

  • ORMT_3D_OBLATE_ELLIPSOID
    • Oblate ellipsoid RD instance: Clark 1866 ellipsoid
      • semi-major axis 6378206.4 m
      • inverse flattening 294.9786982
    • Binding (not part of the SRM specification)
      • Meades Ranch, Kansas on the oblate ellipsoid surface with long=98°32’30.506” W, lat=39°13’26.686” N and surface normal ?= -1.32 ?=1.93.
    • ORM reference transformation:
      • specification of the binding by 7 parameters w.r.t WGS 84 ORM
        • origin offset: ?x = -8, ?y = 160, ?z = 176
        • axis rotations ?1= 0, ? 2 = 0, ? 3 = 0
        • scale adjustment ?s = 0
