WhiteboxTools is an advanced geospatial data analysis platform developed by Prof. John Lindsay at the University of Guelph’s Geomorphometry and Hydrogeomatics Research Group. The WhiteboxTools library currently contains 426 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.
WhiteboxTools can be accessed either from a command prompt (i.e. terminal) or through one of the following front-ends:
The whitebox Python package can be installed using the following command:
pip install whitebox
The whitebox Python package is also available on conda-forge, which can be installed using the following command:
conda install -c conda-forge whitebox
Tool names in the whitebox Python package can be called using the snake_case convention (e.g. lidar_info). See below for an example Python script.
import os import pkg_resources import whitebox wbt = whitebox.WhiteboxTools() print(wbt.version()) print(wbt.help()) # identify the sample data directory of the package data_dir = os.path.dirname(pkg_resources.resource_filename("whitebox", 'testdata/')) wbt.set_working_dir(data_dir) wbt.verbose = False wbt.feature_preserving_smoothing("DEM.tif", "smoothed.tif", filter=9) wbt.breach_depressions("smoothed.tif", "breached.tif") wbt.d_inf_flow_accumulation("breached.tif", "flow_accum.tif")
WhiteboxTools also provides a Graphical User Interface (GUI) - WhiteboxTools Runner, which can be invoked using the following Python script:
import whitebox whitebox.Runner()
The whitebox R package is available on R-Forge, which can be installed using the following command:
You can alternatively install the development version of whitebox from GitHub as follows:
if (!require(devtools)) install.packages('devtools') devtools::install_github("giswqs/whiteboxR")
Tool names in the whitebox R package can be called using the snake_case (e.g. wbt_lidar_info). See below for an example.
library(whitebox) # Set input raster DEM file dem <- system.file("extdata", "DEM.tif", package="whitebox") # Run tools wbt_feature_preserving_smoothing(dem, "./smoothed.tif", filter=9, verbose_mode = TRUE) wbt_breach_depressions("./smoothed.tif", "./breached.tif") wbt_d_inf_flow_accumulation(dem, "./flow_accum.tif")
Depcompress the downloaded zip file.
Navigate to the Folder Connections node in the catalog window tree.
Right-click the node and choose Connect To Folder.
Type the path or navigate to the WhiteboxTools-ArcGIS folder and click OK.
Browse into the toolbox and start using its tools.
Open any tool within the toolbox and start using it. Check out the WhiteboxTools User Mannual for more detailed help documentation of each tool.
Please follow the installation guide here.
You can download a copy of the WhiteboxTools executable for your operating system from the Geomorphometry and Hydrogeomatics Research Group website. Once you’ve downloaded WhiteboxTools and decompressed (unzipped) the folder, you can open a command prompt and start using it.
WhiteboxTools is a command-line program and can be run by calling it with appropriate commands and arguments, from a terminal application. The following commands are recognized by the WhiteboxTools library:
|–cd, –wd||Changes the working directory; used in conjunction with –run flag.|
|-h, –help||Prints help information.|
|-l, –license||Prints the whitebox-tools license.|
|–listtools||Lists all available tools, with tool descriptions. Keywords may also be used, –listtools slope.|
|-r, –run||Runs a tool; used in conjunction with –cd flag; -r=”LidarInfo”.|
|–toolbox||Prints the toolbox associated with a tool; –toolbox=Slope.|
|–toolhelp||Prints the help associated with a tool; –toolhelp=”LidarInfo”.|
|–toolparameters||Prints the parameters (in json form) for a specific tool; –toolparameters="LidarInfo".|
|-v||Verbose mode. Without this flag, tool outputs will not be printed.|
|–viewcode||Opens the source code of a tool in a web browser; –viewcode="LidarInfo".|
|–version||Prints the version information.|
Generally, the Unix convention is that single-letter arguments (options) use a single hyphen (e.g. -h) while word-arguments (longer, more descriptive argument names) use double hyphen (e.g. –help). The same rule is used for passing arguments to tools as well. Use the –toolhelp argument to print information about a specific tool (e.g. –toolhelp=Clump). Tool names can be specified either using the snake_case or CamelCase convention (e.g. lidar_info or LidarInfo).
For examples of how to call functions and run tools from WhiteboxTools, see the whitebox_example.py Python script, which itself uses the whitebox_tools.py script as an interface for interacting with the executable file.
In addition to direct command-line and script-based interaction, a very basic user-interface called WB Runner can be used to call the tools within the WhiteboxTools executable file, providing the required tool arguments.
Example command prompt:
>>./whitebox_tools --wd='/Users/johnlindsay/Documents/data/' --run=DevFromMeanElev --input='DEM clipped.dep' --output='DEV raster.dep' -v
Notice the quotation marks (single or double) used around directories and filenames, and string tool arguments in general. Use the ‘-v’ flag (run in verbose mode) to force the tool print output to the command prompt. Please note that the whitebox_tools executable file must have permission to be executed; on some systems, this may require setting special permissions. The ‘»’ is shorthand for the command prompt and is not intended to be typed. Also, the above example uses the forward slash character (/), the directory path separator used on unix based systems. On Windows, users should use the back slash character (\) instead.
