The **whitebox** R package is built on **WhiteboxTools**, an advanced geospatial data analysis platform developed by Prof. John Lindsay ([webpage](https://jblindsay.github.io/ghrg/index.html); [jblindsay](https://github.com/jblindsay)) at the University of Guelph's [Geomorphometry and Hydrogeomatics Research Group](https://jblindsay.github.io/ghrg/index.html). *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, analyzed 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.

## Installation
There are three ways to install the **whitebox** R package.
### 1. CRAN
**whitebox** is now available on [CRAN](https://cran.r-project.org/package=whitebox), so you can install it with:
```R
install.packages("whitebox")
```### 2. GitHub
You can alternatively install the development version of **whitebox** from [GitHub](https://github.com/opengeos/whiteboxR) as follows:
```R
if (!require("remotes")) install.packages('remotes')
remotes::install_github("opengeos/whiteboxR", build = FALSE)
```## Usage
The function `wbt_init()` checks the path to the 'WhiteboxTools' binary.
```r
wbt_init()
```
It (invisibly) returns a logical (TRUE/FALSE) value reflecting whether a file is found at one of the default paths, including those specified by package options. See `?whitebox::whitebox`.
If you have 'WhiteboxTools' installed already but in a non-standard location run `wbt_init(exe_path=...)` to set up your options for your current R session.```{r, eval=FALSE}
wbt_init(exe_path = 'C:/home/user/path/to/whitebox_tools.exe')
```Additional arguments to `wbt_init()` can set other package options, such as whether tools print their standard console output with `cat()`.
If you want to turn this off, set `verbose = FALSE`, for instance:
```{r, eval=FALSE}
wbt_init(exe_path = 'C:/home/user/path/to/whitebox_tools.exe', verbose = FALSE)
```## Documentation
For whitebox package documentation in R, ask for help:
```r
??whitebox
```For list of functions, try the `wbt_` prefix in your search:
```r
??wbt_
```A complete list of functions available in the **whitebox** R package can be found [HERE](https://whiteboxR.gishub.org/reference/index.html).
Check out this [demo](https://whiteboxR.gishub.org/articles/demo.html) for examples.
## Installing 'WhiteboxTools'
The quickest way to get started if you are on 64-bit Windows, Linux or MacOS architectures is to download and install the 'WhiteboxTools' binary. Linux binaries compiled with 'musl' instead of 'glibc' on Ubuntu 22.04 are available with `platform="linux_musl"`. On MacOS, Intel and Apple 'M' series processors ('arm64') are supported.
A method `install_whitebox()` is provided to download a version of the binaries that corresponds to the wrapper functions available in the package.
```{r, eval=FALSE}
whitebox::install_whitebox()
```By default this will install 'WhiteboxTools' to your whitebox R package data directory (see `wbt_data_dir()`), subdirectory "WBT".
## whitebox
**How do I run tools?**
Tool names in the whitebox R package can be called by corresponding function using `wbt_snake_case()` naming convention (e.g. `wbt_lidar_info()` R function for `"LidarInfo"` 'WhiteboxTools' tool name).
First we load the library and perform any necessary setup.
```{R}
library(whitebox)# set up as needed
wbt_init()
```Many 'WhiteboxTools' will take GeoTIFF files as input, but 'WhiteboxTools' supports several grid input formats. There is a sample Digital Elevation Model (DEM) included in the whitebox package. You can get path as follows for this demo:
```{R}
# Set input raster DEM file
dem <- sample_dem_data()
```We will use this DEM in a sequence of 'WhiteboxTools' processing routines.
Run tools by passing file paths for the input and output files.1. Apply feature-preserving smoothing (_FeaturePreservingSmoothing_)
2. Breach depressions in a DEM (_BreachDepressions_)
3. Calculate D-Infinity flow accumulation (_DInfFlowAccumulation_)The `filter` argument to `wbt_feature_preserving_smoothing()` sets the size of the filter kernel.
```{r}
## 1. FeaturePreservingSmoothing
wbt_feature_preserving_smoothing(
dem = dem,
output = "./smoothed.tif",
filter = 9
)## 2. BreachDepressions
wbt_breach_depressions(dem = "./smoothed.tif", output = "./breached.tif")## 3. DInfFlowAccumulation
wbt_d_inf_flow_accumulation(input = dem, output = "./flow_accum.tif")
``````{r terra-plot-facc}
if (requireNamespace('terra')) {
terra::plot(terra::rast("./flow_accum.tif"))
}
```**About 'WhiteboxTools'**
```{r}
library(whitebox)# cat() output in non-interactive mode
wbt_verbose(TRUE)# Prints the whitebox-tools help...a listing of available commands
wbt_help()# Prints the whitebox-tools license
wbt_license()# Prints the whitebox-tools version
wbt_version()# Prints the toolbox for a specific tool.
wbt_toolbox("AsciiToLas")# Lists tools with 'lidar' in tool name or description.
wbt_list_tools("lidar")# Prints the help for a specific tool.
wbt_tool_help("lidar_info")# Retrieves the tool parameter descriptions for a specific tool.
wbt_tool_parameters("slope")# View the source code for a specific tool on the source code repository.
wbt_view_code("breach_depressions")
```## Available Tools
The **[WhiteboxTools](https://github.com/jblindsay/whitebox-tools)** library currently contains more than **`r nrow(wbttools)`** 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. For a listing of available tools, complete with documentation and usage details, please see the ['WhiteboxTools' User Manual](https://jblindsay.github.io/wbt_book/available_tools/index.html).
If you are interested in using the 'WhiteboxTools' command-line program, check ['WhiteboxTools' Usage](https://github.com/jblindsay/whitebox-tools#3-usage)
