Common mistakes with Gulshan 303 / TM 90 NE
- Easting and northing swapped. In Gulshan 303 / TM 90 NE the middle of the grid is near easting 534,976.54 and northing 2,607,474.23. If your easting column holds numbers like 2,607,474.23, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Gulshan 303 / TM 90 NE 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. Gulshan 303 / TM 90 NE 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. Gulshan 303 / TM 90 NE is meant for Bangladesh - onshore. 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.
