Processing point cloud in R – Follow-up

  Monday, you had an opportunity to process a drone-based point cloud using R and the lidR and the rgdal packages.  You should have familiarized yourself with the following commands and at least have an idea of what they do: plot() summary() lasfilterdecimate(): lasground(): lasnormalize(): lasfilter(): grid_metrics(): grid_canopy(): […]

Processing point cloud in R

    Lab 07:  Process point cloud in R!!! In this lab, you will use the R programming language to process a point cloud.  As in previous labs, the goal is to automatically count trees across the landscape.  These methods are relevant even if you are not interested in tree-counting.  […]

SeGrowers Data Processing in R – Demo

Monday, you stepped through a simple analysis in ArcMap.  You created a normalized surface model (I called it the DZM in the lab document) by differencing the surface model (DSM) and the terrain model (DTM).  The resulting raster layer contains cells whose values are 0 or near-zero.  These cells represent […]
