WhiteboxTools R Frontend.
This repository is related to the whitebox R package for geospatial analysis, which is an R frontend of a stand-alone executable command-line program called WhiteboxTools.
The whitebox R package is built on WhiteboxTools, an advanced geospatial data analysis platform developed by Prof. John Lindsay (webpage; jblindsay) at the University of Guelph's Geomorphometry and Hydrogeomatics Research Group. WhiteboxTools can be used to perform common geographical information systems (GIS) analysis operations, such as cost-distance analysis, distance buffering, and raster reclassification. Remote sensing and image processing tasks include image enhancement (e.g. panchromatic sharpening, contrast adjustments), image mosaicing, numerous filtering operations, simple classification (k-means), and common image transformations. WhiteboxTools also contains advanced tooling for spatial hydrological analysis (e.g. flow-accumulation, watershed delineation, stream network analysis, sink removal), terrain analysis (e.g. common terrain indices such as slope, curvatures, wetness index, hillshading; hypsometric analysis; multi-scale topographic position analysis), and LiDAR data processing. LiDAR point clouds can be interrogated (LidarInfo, LidarHistogram), segmented, tiled and joined, analyized for outliers, interpolated to rasters (DEMs, intensity images), and ground-points can be classified or filtered. WhiteboxTools is not a cartographic or spatial data visualization package; instead it is meant to serve as an analytical backend for other data visualization software, mainly GIS.

There are three ways to install the whitebox R package.
whitebox will be available on CRAN soon. Once it is available on CRAN, you can install it with:
whitebox is now available on R-Forge, so you can install it with:
You can alternatively install the development version of whitebox from GitHub as follows:
if (!require(devtools)) install.packages('devtools') devtools::install_github("giswqs/whiteboxR")
You’ll also need to make sure your machine is able to build packages from source. See Package Development Prerequisites for the tools needed for your operating system.
library(whitebox) # Prints the whitebox-tools help...a listing of available commands print(wbt_help()) # Prints the whitebox-tools license print(wbt_license()) # Prints the whitebox-tools version print(wbt_version()) # Prints the toolbox for a specific tool. print(wbt_toolbox()) # List all available tools in whitebox-tools print(wbt_list_tools()) # Lists tools with 'lidar' in tool name or description. print(wbt_list_tools("lidar")) # Prints the help for a specific tool. print(wbt_tool_help("lidar_info")) # Retrieves the tool parameter descriptions for a specific tool. print(wbt_tool_parameters("slope")) # View the source code for a specific tool on the source code repository. print(wbt_view_code("breach_depressions"))
How to run tools?
Tool names in the whitebox R package can be called using the snake_case (e.g. lidar_info). See below for an example. If you are interested in using the WhiteboxTools command-line program, check WhiteboxTools Usage.
library(whitebox) # Set input raster DEM file dem <- system.file("extdata", "DEM.tif", package="whitebox") # Run tools feature_preserving_denoise(dem, "./smoothed.tif", filter=9) breach_depressions("./smoothed.tif", "./breached.tif") d_inf_flow_accumulation(dem, "./flow_accum.tif", verbose_mode = FALSE)
The WhiteboxTools library currently contains more than 396 tools, which are each grouped based on their main function into one of the following categories: Data Tools, GIS Analysis, Hydrological Analysis, Image Analysis, LiDAR Analysis, Mathematical and Statistical Analysis, Stream Network Analysis, and Terrain Analysis. The following is a complete listing of available tools, with brief tool descriptions.
