LiDAR links

For those of you wanting to know more about LiDAR images mentioned by Colin Merrony in his excellent talk ‘2000 years in the Hope Valley’ on Monday May 16th, here’s a few pointers on how to access available images.

Firstly, take a look at… which a zoomable interactive map.

Colour images for the Chesterfield area can be found on Flicker. You will need to know the Ordnance Survey map reference – find this here by zooming in to the area of your choice –…

Then visit the Defra site on Flicker –…/environmentagencyopensu…/albums. Using the Flicker search function, type in the OS map reference. This will open the appropriate album. Note that the survey images are not complete and fairly low resolution. For example searching SK47SW (Brimington/Staveley area) will reveal only four images – with incomplete coverage.

Chesterfield and west of Chesterfield – SK37SE – has four images all complete. Some interesting features are revealed, but some need specialist knowledge to interpret.
