Common mistakes with Camacupa 1948 / TM 12 SE
- Feet entered as metres. Camacupa 1948 / TM 12 SE 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. Camacupa 1948 / TM 12 SE 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. Camacupa 1948 / TM 12 SE is meant for Angola - Angola proper - offshore. 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.
