An online step-by-step resource guide for conducting remote tree censuses using LiDAR data with R and other open-source software tools.
The following packages are needed:
# Install Packages
install.packages( "here" )
install.packages( "lidR" )
install.packages( "rLiDAR" )
install.pacakges( "raster" )
install.packages( "sp" )

# Library
library( "here" ) # Used to create relative file paths so that code is reproducible
library( "lidR" ) # Used for LiDAR file processing
library( "rLiDAR" ) # Used for LiDAR file processing
library( "raster" ) # Used for raster file processing
library( "sp" ) # Used for mapping and spatial data processing
library( "ggmap" ) # Used for mapping and spatial data processing
library( "measurements" ) # Used to convert measurement units
library( "kableExtra" ) # Used to format tables
library( "tidyverse" ) # Used for manipulating data and packages
The LiDAR data set was accessed from Arizona State University Library’s Map and Geospatial Hub. Tiles 2333.tif and 2433.tif from the Phoenix, Arizona USGS data set are used in the code-through. Details are available here.
