Common mistakes with Ain el Abd / Aramco Lambert
- Easting and northing swapped. In Ain el Abd / Aramco Lambert the middle of the grid is near easting -292,582.86 and northing -87,347.59. If your easting column holds numbers like -87,347.59, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Ain el Abd / Aramco Lambert 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. Ain el Abd / Aramco Lambert is not on WGS 84: published 3-parameter shift (typically a few metres). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Ain el Abd / Aramco Lambert is meant for Saudi Arabia - onshore. 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.
