The measurements have been produced in conjunction with the following UK government statistical organisations and independent mapping agencies: National Records of Scotland; Northern Ireland Statistics and Research Agency; Office for National Statistics; Ordnance Survey®; Land & Property Services and Ordnance Survey of Northern Ireland®.

The SAM User Guide explains differences in methodology and base mapping between these agencies.
