OS Landform PANORAMA® is a 1:50,000 scale terrain dataset covering the whole of Great Britain and is available as both a 50m digital terrain model (DTM) and contours.

The contour data consists of vectorised contours at 10m vertical intervals, as well as spot heights, breaklines, the coastline, ridgelines, formlines and lakes. The dataset was created using traditional photogrammetry techniques during the production of the OS Landranger 1:50,000 dataset and mirrors the contour lines which appear on raster and paper mapping of equivalent scale.

Users should note that this is a "frozen" dataset and for information on accuracy and usage should consult the Landform PANORAMA® product guide.
