Common mistakes with GDM2000 / Selangor Grid
- Easting and northing swapped. In GDM2000 / Selangor Grid the middle of the grid is near easting -37,515.67 and northing 3,425.31. If your easting column holds numbers like 3,425.31, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. GDM2000 / Selangor Grid 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. GDM2000 / Selangor Grid 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. GDM2000 / Selangor Grid is meant for Malaysia - West Malaysia - Selangor. 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.
