Common mistakes with Grand Cayman National Grid 1959
- Metres entered as feet. Grand Cayman National Grid 1959 is in international feet. Enter the values as they are; converting them to metres first puts every point in the wrong place.
- Forgetting the datum. Grand Cayman National Grid 1959 is not on WGS 84: published 7-parameter shift (typically 1–2 m). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Grand Cayman National Grid 1959 is meant for Cayman Islands - Grand Cayman. 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.
