      Coordinate System and Datums

      The coordinate system used is the British National Grid used by the Ordnance Survey of Great Britain which is based on the OSGB36 geodetic datum and uses the Transverse Mercator projection.

      This system has a notation comprising letter and number combinations for 100x100km tiles (eg SU, TQ etc), 10x10km tiles (eg SU26, TQ69 etc) and 1x1km tiles (eg SU2965, TQ6496 etc).

      The British National Grid is a two dimensional (x,y) reference system only. The vertical datum (mean sea level) used is the Ordnance Survey Newlyn Datum.

       

      Metadata

      Metadata is supplied with all Height Data Products. The metadata is supplied as an XML file that has the same name as the Height Data Product concerned and is stored in the same directory.
