How to use this calculator
- Enter the original easting and northing.
- Enter the ΔE and ΔN offsets.
- Press Calculate.
How it works
Applies a straight easting/northing offset to a coordinate: new E = E + ΔE, new N = N + ΔN.
Worked example
Offset +10 E, −5 N. Shifts the point 10 m east and 5 m south.
Frequently asked questions
Can I offset along a bearing instead?
Use the bearing-and-distance to coordinates tool for an offset along a direction; this one applies a straight ΔE/ΔN.
