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.

Range and reflectance calibration measurement

We have been testing the range dependence of the SALCA returns in a series of indoor experiments. The objective is to derive an empirical range corrections that can be applied to the waveforms in order to move forward with quantitative analysis of the intensity information. Alberto has derived a field based method for the Riegl scanners and we will compare this approach with the results from the lab calibration.
