Common mistakes with MGI (Ferro) / Austria GK West Zone

  • Feet entered as metres. MGI (Ferro) / Austria GK West Zone is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
  • Forgetting the datum. MGI (Ferro) / Austria GK West Zone is not on WGS 84: treated as WGS 84, no shift (the datums agree to about a metre or better). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
  • Points outside the grid's area. MGI (Ferro) / Austria GK West Zone is meant for Austria west of 11°50'E of Greenwich (29°30'E of Ferro). Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
  • A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
