Common mistakes with JGD2000 / Japan Plane Rectangular CS XI
- Easting and northing swapped. In JGD2000 / Japan Plane Rectangular CS XI the middle of the grid is near easting 12,352.17 and northing -179,947.34. If your easting column holds numbers like -179,947.34, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. JGD2000 / Japan Plane Rectangular CS XI 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. JGD2000 / Japan Plane Rectangular CS XI 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. JGD2000 / Japan Plane Rectangular CS XI is meant for Japan - onshore - Hokkaido west of approximately 141°E - Otaru city; Hakodate city; Date city; Usu-gun and Abuta-gun of Iburi-shicho; Hiyama-shicho; Shiribeshi-shicho; Oshima-shicho. 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.
