Each postcode in the ONS Postcode Directory is assigned an elevation based on the nearest point on a contour line from OS Terrain 50 to the approximate centre of the postcode.

Note that the centre of the postcode is typically the position of the building closest to the postcode mean - other buildings within the same postcode could have the same elevation, or significantly different elevations.

OS Terrain 50 has contour spacing of ten vertical metres.
