Common mistakes with NAD83(2011) / RMTCRS Wind River (m)
- Which column is which. In NAD83(2011) / RMTCRS Wind River (m) eastings and northings near the middle of the grid are of similar size (about 68,604.25 and 67,669.91), so a swap won't be obvious from the numbers. Check that the first point lands where you expect it before converting the rest.
- Feet entered as metres. NAD83(2011) / RMTCRS Wind River (m) 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. NAD83(2011) / RMTCRS Wind River (m) 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) / RMTCRS Wind River (m) is meant for United States (USA) - Wyoming - Wind River Indian Reservation. 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.
