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(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasfilterdecimate lasground(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasground lasnormalize(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasnormalize lasfilter(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/lasfilters grid_metrics(): https://www.rdocumentation.org/packages/lidR/versions/2.0.0/topics/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 […]

Week 6 Lab: Rubber sheeting w/ the georeferencing toolbar

Georeferencing practice (Oconee Forest Park) OCFP SAMPLE DATA Set up your ArcMap project Load your georeferenced source image (NAIP2015_Source.jpg) Ensure your data frame coordinate system matches the NAIP (UTM17/NAD83/Zone17N…) Load your ungeoreferenced target image this layer is not georeferenced, you will not see it when it loads Save the project to your workspace Locate possible ground […]


Queries: RCW Site Assessment

    Data  Download the RCW data linked on our ELC site. Copy the zipped file over to your working folder on the E:\ drive and unzip it.  I converted the data to feature classes in a file geodatabase.  We realized that there were inconsistencies with the original shapefiles (2/13/2020). The […]
