Common mistakes with Beijing 1954 / 3-degree Gauss-Kruger CM 117E

  • Feet entered as metres. Beijing 1954 / 3-degree Gauss-Kruger CM 117E 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. Beijing 1954 / 3-degree Gauss-Kruger CM 117E 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. Beijing 1954 / 3-degree Gauss-Kruger CM 117E is meant for China - onshore between 115°30'E and 118°30'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.
