Common mistakes with NAD 1983 HARN SPCS Hawaii Zone 4 (US Feet)
- Metres entered as feet. NAD 1983 HARN SPCS Hawaii Zone 4 (US Feet) 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 1983 HARN SPCS Hawaii Zone 4 (US Feet) 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 1983 HARN SPCS Hawaii Zone 4 (US Feet) is meant for USA - Hawaii - Kauai - onshore. 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.
