Common mistakes with NAD 1927 SPCS Zone Guam

  • Metres entered as feet. NAD 1927 SPCS Zone Guam is in US survey feet. Enter the values as they are; converting them to metres first puts every point in the wrong place.
  • Forgetting the datum. NAD 1927 SPCS Zone Guam 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. NAD 1927 SPCS Zone Guam is meant for Guam. 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.
