Common mistakes with New York Long Island State Plane (m)
- Easting and northing swapped. In New York Long Island State Plane (m) the middle of the grid is near easting 381,750.74 and northing 80,221.17. If your easting column holds numbers like 80,221.17, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. New York Long Island State Plane (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. New York Long Island State Plane (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. New York Long Island State Plane (m) is meant for United States (USA) - New York - counties of Bronx; Kings; Nassau; New York; Queens; Richmond; Suffolk. 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.
Before you rely on it
Most New York City work is in US survey feet (EPSG 2263). If your numbers are about 3.28 times larger than expected, pick EPSG 2263 in the grid list. Always check one known control point before sending a file out.
