Common mistakes with JGD2000 / Japan Plane Rectangular CS XVIII
- Easting and northing swapped. In JGD2000 / Japan Plane Rectangular CS XVIII the middle of the grid is near easting 9,391.77 and northing 47,048.33. If your easting column holds numbers like 47,048.33, 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 XVIII 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 XVIII 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 XVIII is meant for Japan - onshore - Tokyo-to south of 28°N and west of 140°30'E. 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.
