Common mistakes with NAD83(HARN) / California Albers
- Easting and northing swapped. In NAD83(HARN) / California Albers the middle of the grid is near easting 63,315.47 and northing -82,731.13. If your easting column holds numbers like -82,731.13, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. NAD83(HARN) / California Albers 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) / California Albers 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) / California Albers is meant for United States (USA) - California. 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.
