Common mistakes with Kalianpur 1975 / India zone IIb
- Easting and northing swapped. In Kalianpur 1975 / India zone IIb the middle of the grid is near easting 2,714,303.60 and northing 829,730.50. If your easting column holds numbers like 829,730.50, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Kalianpur 1975 / India zone IIb 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. Kalianpur 1975 / India zone IIb 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. Kalianpur 1975 / India zone IIb is meant for India - onshore north of 21°N and east of 82°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.
