Common mistakes with Indian 1960 / UTM zone 49N

  • Feet entered as metres. Indian 1960 / UTM zone 49N 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. Indian 1960 / UTM zone 49N 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. Indian 1960 / UTM zone 49N is meant for Vietnam - onshore east of 108°E. 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.
