 ABSTRACT  OF  THE  TEACHER    

MARTIN  ISENBURG  

 Wednesday  -­  6th  July,  Thursday  –  7th  July  

LLS  -­  LiDAR  quality  checking,  processing,  derivatives,  full  waveform  Complete  LiDAR  processing  pipeline:  

Part  1,  Quality  Checking:  the  LAS  format,  visual  inspection,  LAS  file  validation,  flightline  overlap  and  alignment,  pulse  density  and  spacing  calculations  

Part  2,  LiDAR  preparation:  compression,  spatial  indexing,  tiling,  buffering,  noise  removal,  ground  classification,  building  and  vegetation  classification.  

Part  3,  LiDAR  product  generation:  DTM  /  DSM,  intensity  grids,  building  outlines,  contour  line  generation  

Part  4,  forestry  metrics,  CHM  rasters,  pit-­free  and  spike-­free  algorithms,  intro  to  full  waveform  LiDAR
