Retrieval of Gap Fraction and Effective Plant Area Index from Phase-Shift Terrestrial Laser Scans

Pyare Pueschel, Glenn Newnham, Joachim Hill
2014 Remote Sensing  
Two commonly used metrics for characterizing canopy structure are the gap fraction and the effective Plant Area Index (PAI e ). Both have been successfully retrieved with terrestrial laser scanning.  ...  However, a systematic assessment of the influence of the laser scan properties on the retrieval of these metrics is still lacking.  ...  Glenn Newnham provided IDL code for the processing of raw scan data, contributed to the discussion and interpretation of results, and contributed some portions of the written manuscript.  ...
