Kim Calders (at the National Physical Laboratory and University College London) and Mat Disney (at University College London) have been scanning parts of the plot with Terrestrial Laser Scanners in summer and winter 2015. Kim has also been working on the airborne lidar data over Wytham, provided by David Coomes' team at Cambridge, and originally collected by NERC ARSF as part of the AIRSAR campaign.
Mat has written a nice post about this work here
The image show shows a transect and shows what is possible. The red dots indicate laser returns from the summer (mainly from leaves). The green dots are returns from the winter scans (manly from wood and evergreen leaves). The blue dots show what is detected from the airborne lidar in summer (mainly the top surface of the canopy).
In combination, these data depict an wonderfully detailed 3D representation of the woodland of which this is just a cross-section. This patch contains a dense patch of ash and sycamore of roughly even age and size, a legacy of recovery form disturbance in the 1940s and early 1950s. Hence the dense canopy of crowns tightly packed and competing for space, and the lack of gaps in canopy space from tree mortality. We can also begin to estimate and map leaf area and biomass by comparing winter and summer scans. Data such as these open new prospects in not just forest mapping, but in understanding forest ecology, dynamics and animal habitats. They look gorgeous too!
