If you tuned in to BBC’s Countryfile on Sunday, you’ll have seen Roger Nock from our Flying Unit talking to Adam Henson at his Cotswold farm. We were talking about how the aerial imagery we fly in our planes has been used to map hedgerows for the Rural Payments Agency, and help work out subsidies for farmers. We showed an example of how 3D data can be captured and displayed over Adam’s farm.
After the programme, we received a tweet asking where the LiDAR camera was in our plane. The answer is simply that we don’t fly LiDAR (3D laser scanning of the ground) and our planes are surveying aerial imagery (taking a photo with a high-resolution camera on-board the plane). We are treating this imagery in a similar way to how others would work with LiDAR data though.

If you were watching BBC Breakfast yesterday morning, you may have seen a feature about OS mapping Britain from the skies and interpreting that data into 3D maps to create a digital twin of our real-life landscape.
