Common mistakes with Kertau (RSO) / RSO Malaya (ch)
- Which column is which. In Kertau (RSO) / RSO Malaya (ch) eastings and northings near the middle of the grid are of similar size (about 22,649.73 and 21,800.68), so a swap won't be obvious from the numbers. Check that the first point lands where you expect it before converting the rest.
- Feet entered as metres. Kertau (RSO) / RSO Malaya (ch) 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. Kertau (RSO) / RSO Malaya (ch) 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. Kertau (RSO) / RSO Malaya (ch) is meant for Malaysia - West Malaysia 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.
