Common mistakes with Ocotepeque 1935 / Costa Rica Sur

  • Easting and northing swapped. In Ocotepeque 1935 / Costa Rica Sur the middle of the grid is near easting 448,285.46 and northing 323,755.20. If your easting column holds numbers like 323,755.20, the columns are the wrong way round and every point lands far away: swap them before converting.
  • Feet entered as metres. Ocotepeque 1935 / Costa Rica Sur 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. Ocotepeque 1935 / Costa Rica Sur 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. Ocotepeque 1935 / Costa Rica Sur is meant for Costa Rica - onshore south of 9°56'N. 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.
