Spring is coming - let's get scanning

Yesterday Mark and Fadal were back at Silverdale in Lancashire, scanning three oak trees in leaf-off state. These trees feature in our recent paper "Spectral and spatial information from a novel dual-wavelength full-waveform terrestrial laser scanner for forest ecology" publish in Interface Focus and available here:
 
The leaf-on data were collected around 18 months ago and in the paper we compare spectral classification using the SALCA Normalised Difference Index (NDI) with spatial classification using Canupo in CloudCompare
 
The new data will allow us to explore further the application of SALCA for leaf and wood classification.
