Common mistakes with American Samoa 1962 / American Samoa Lambert
- Easting and northing swapped. In American Samoa 1962 / American Samoa Lambert the middle of the grid is near easting 454,423.40 and northing 309,210.50. If your easting column holds numbers like 309,210.50, the columns are the wrong way round and every point lands far away: swap them before converting.
- Metres entered as feet. American Samoa 1962 / American Samoa Lambert is in US survey feet. Enter the values as they are; converting them to metres first puts every point in the wrong place.
- Forgetting the datum. American Samoa 1962 / American Samoa 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. American Samoa 1962 / American Samoa Lambert is meant for American Samoa - Tutuila, Aunu'u, Ofu, Olesega and Ta'u islands. 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.
