Common mistakes with OSGB 1936 Highways England C14H2
- Feet entered as metres. OSGB 1936 Highways England C14H2 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. OSGB 1936 Highways England C14H2 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. OSGB 1936 Highways England C14H2 is meant for UK - Highways England - C14. 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.
