Sorry to hear about your house, my entire principality is missing, as the Welsh data is now looked after by the devolved equivalent agency, Natural Resources Wales. Happily it appears that&#x27;s due to be released on November 2nd (<a href="http:&#x2F;&#x2F;naturalresources.wales&#x2F;lidar?lang=en" rel="nofollow">http:&#x2F;&#x2F;naturalresources.wales&#x2F;lidar?lang=en</a>) so hopefully I&#x27;ll be able to incorporate that shortly after, depending on what it looks like.<p>The current map is built with all the available DSM (Digital Surface Model) 1m resolution data. It appears the coverage is focused on coast and rivers, which makes sense in light of the Environment Agency&#x27;s flooding remit. There&#x27;s more coverage available to download at 2m (covering approximately half of the 1m gaps at a guess) and some small patches available at 50cm and 25cm resolutions.
