Common mistakes with Belge Lambert 1972 more precise false easting and northing values

• Feet entered as metres. Belge Lambert 1972 more precise false easting and northing values 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. Belge Lambert 1972 more precise false easting and northing values 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. Belge Lambert 1972 more precise false easting and northing values is meant for Belgium - 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.
