LIDAR

I know that LIDAR has been mentioned here before but wanted to makepeople aware that there was a zoomable UK map available

A bit about LIDAR here
historicengland.org.uk/research/approach...emote-sensing/lidar/

The map is not of 100% of the UK presumably because most of the work is funded by the Environment Agency so it concentrates on rivers and coastlines, for the assessment of flooding and errosion.

So I have been able to look at the range arrows at Donna Nook, the Lightning at Skegness Park, former RAF North Coates (where there is not even a glimmer of the former Bloodhound site), the Bloodhound site at Bawdsey, where all the concrete and earthworks show up well. Other sites like St Mawgan, Chivenor and Hartland Point are also visible.

Certainly the quality is sufficient to identify earthworks such as fighter pens

I think this is a very useful tool but the definition is not yet good enough, for free, to spot the things I am looking for. The best bit is looking at woodland but sadly hidden concrete arrows don't show up as there is no height difference. Still recent forest clearance has revealed two in the last 6 years

I continue to make occasional use of this tool

LIDAR data
The Environment Agency have just released their LIDAR (Light Detection and Ranging) data under an Open Government Licence.

The composite data covers over 72% of England (no Wales, Scotland or Northern Ireland yet as this data's held by the devolved agencies). Resolutions available are 25cm, 50cm, 1m, and 2m, but coveraage appears very limited at the higher resolutions. The 1m data appears to strike a good balance of coverage and detail, so have mostly been looking at that.

Have grabbed some of the DSM 1 meter data and drawn some map tiles with contour shading shading to produce a zoomable map.

Particularly useful as it accepts OS Grid References as well as names

So this is the former Humberston CHL site before demolition

And in the centre of this is the remains of the jetty at former RNAS Killingholme

This site gives a split screen view of a location where the top half is Google maps satellite and the lower is the LIDAR map

Note that these are adjacent areas North and South of a centre, unlike for instance wheresthepath

LIDAR is generally only available in coastal areas and those area at risk of flooding

Here is an example which cuts through Donna Nook s Ops Block

Brilliant. Much easier to find the correct location.

The NLS mapsite also has LIDAR for use as background maps but it only works in one type of map search and I can't recall what it was.

I saw the Scottish LIDAR mentioned somewhere, I think this is the site.
