Common mistakes with RGNC91-93 / Lambert New Caledonia
- Easting and northing swapped. In RGNC91-93 / Lambert New Caledonia the middle of the grid is near easting 385,975.94 and northing 342,617.39. If your easting column holds numbers like 342,617.39, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. RGNC91-93 / Lambert New Caledonia 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. RGNC91-93 / Lambert New Caledonia 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. RGNC91-93 / Lambert New Caledonia is meant for New Caledonia - Belep, Grande Terre, Ile des Pins, Loyalty Islands (Lifou, Mare, Ouvea). 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.
