The SALCA diaries

Vegetation structure is important for measuring forest growth and the carbon cycle. Developed by the University of Salford and Halo Photonics Ltd, the Salford Advanced Laser Canopy Analyser (SALCA) is a unique multi-spectral, full waveform laser scanner using two wavelengths allowing distinction between leaves and woody material. This blog follows our research funded by the UK NERC and involving University of Newcastle, University College London and UK Forest Research.

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.

You have completed an intriguing composition and work. It's valid with the assistance of 3d scanning Denver, Colorado you can accomplish increasingly exact and magnificent structures and works.
