Common mistakes with AGD 1966 NSW ISG Zone 55 / 1

  • Feet entered as metres. AGD 1966 NSW ISG Zone 55 / 1 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. AGD 1966 NSW ISG Zone 55 / 1 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. AGD 1966 NSW ISG Zone 55 / 1 is meant for Australia - New South Wales - 144~E to 146~E (ISG 55/1). 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.
