Common mistakes with NAD83(HARN) / Alabama East
- Easting and northing swapped. In NAD83(HARN) / Alabama East the middle of the grid is near easting 199,376.97 and northing 276,640.74. If your easting column holds numbers like 276,640.74, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. NAD83(HARN) / Alabama East 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. NAD83(HARN) / Alabama East 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. NAD83(HARN) / Alabama East is meant for United States (USA) - Alabama east of approximately 86°37'W - counties Barbour; Bullock; Calhoun; Chambers; Cherokee; Clay; Cleburne; Coffee; Coosa; Covington; Crenshaw; Dale; De Kalb; Elmore; Etowah; Geneva; Henry; Houston; Jackson; Lee; Macon; Madison; Marshall; Montgomery; Pike; Randolph; Russell; StClair; Talladega; Tallapoosa. 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.
