Common mistakes with ETRS89 / ETRS-GK22FIN
- Easting and northing swapped. In ETRS89 / ETRS-GK22FIN the middle of the grid is near easting 500,000.00 and northing 7,159,496.69. If your easting column holds numbers like 7,159,496.69, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. ETRS89 / ETRS-GK22FIN 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. ETRS89 / ETRS-GK22FIN 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. ETRS89 / ETRS-GK22FIN is meant for Finland - onshore between 21°30'E and 22°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.
