Common mistakes with GDA94 / Vicgrid
- Which column is which. In GDA94 / Vicgrid eastings and northings near the middle of the grid are of similar size (about 2,544,737.81 and 2,545,375.27), 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. GDA94 / Vicgrid 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. GDA94 / Vicgrid 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. GDA94 / Vicgrid is meant for Australia - Victoria. 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.
