Common mistakes with NAD83(2011) / InGCS Dubois-Martin (ftUS)
- Easting and northing swapped. In NAD83(2011) / InGCS Dubois-Martin (ftUS) the middle of the grid is near easting 808,848.81 and northing 247,406.80. If your easting column holds numbers like 247,406.80, the columns are the wrong way round and every point lands far away: swap them before converting.
- Metres entered as feet. NAD83(2011) / InGCS Dubois-Martin (ftUS) 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. NAD83(2011) / InGCS Dubois-Martin (ftUS) 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. NAD83(2011) / InGCS Dubois-Martin (ftUS) is meant for United States (USA) - Indiana - counties of Dubois and Martin. 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.
