DEM United Kingdom – Highest Obtainable Resolution of Free Elevation Data in the UK

datademelevationunited-kingdom

I am seeking closure with this question guys.

I am aware of various sources of free elevation data ~30+ m, and I have been searching for higher resolution FREE data for a while now. This already exists somewhat (Where to acquire elevation data for UK?), but may have changed since a year.

I'm afraid I may know the answer already, but to put an end to my misery and false hope:

What is the highest resolution, freely available (outside of academic institutions), elevation data covering the ENTIRE UK? – is 10 m available?

Best Answer

OS Terrain 50 contours (10m contours) for Great Britain (England, Scotland and Wales)

It is supplied both as a set of 50m gridded digital terrain model (OS Terrain 50 grid) and 10m contours and spot heights (OS Terrain 50 contours).

Notice: OS Terrain 50 contours and OS Terrain 50 grid are now available as of 8th July 2013.

Tip: Opt for the OS Terrain 50 - ESRI SHAPE (CONTOURS) - GB

Update: 27th October 2015. With a lot of processing it is possible to get even more detailed elevation data (for England currently) from Environmental Agency Opendata LiDAR example http://environment.data.gov.uk/ds/survey#/download?grid=TL45 has 1m res LiDAR which heights of features (including the ground) can be extracted.

A Example of the contours created from LiDAR are here http://relief.raggedred.net/#18/53.76828/-0.36981 (Layers button 'contours') and zoom in.
