Common mistakes with WGS 84 / SCAR IMW SU41-45
- Easting and northing swapped. In WGS 84 / SCAR IMW SU41-45 the middle of the grid is near easting 0.00 and northing 888,469.93. If your easting column holds numbers like 888,469.93, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. WGS 84 / SCAR IMW SU41-45 is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Looking for a datum shift that isn't there. WGS 84 / SCAR IMW SU41-45 is defined on WGS 84, the datum Google Earth uses, so no shift is applied. If points are off by tens or hundreds of metres, the data is probably on another grid.
- Points outside the grid's area. WGS 84 / SCAR IMW SU41-45 is meant for Antarctica - 80°S to 84°S and 60°E to 90°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.
