1 Description

WhiteboxTools is 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, classification, 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.

3 Pre-compiled binaries

WhiteboxTools is a stand-alone executable command-line program with no actual installation. If you intend to use the Python programming interface for WhiteboxTools you will need to have Python 3 (or higher) installed. Pre-compiled binaries can be downloaded from the Whitebox Geospatial Inc. website with support for various operating systems.

4 Building from source code

It is likely that WhiteboxTools will work on a wider variety of operating systems and architectures than the distributed binary files. If you do not find your operating system/architecture in the list of available WhiteboxTool binaries, then compilation from source code will be necessary. WhiteboxTools can be compiled from the source code with the following steps:

  1. Install the Rust compiler; Rustup is recommended for this purpose. Further instruction can be found at this link.

  2. Download the WhiteboxTools from this GitHub repo.

  3. Decompress the zipped download file.

  4. Open a terminal (command prompt) window and change the working directory to the whitebox-tools folder:

>> cd /path/to/folder/whitebox-tools/
  1. Finally, use the Python build.py script to compile the code:
>> python build.py

Read the notes in the build.py file for detailed information about customizing the build. In particular, the do_clean, exclude_runner and zip arguments can be used to add or remove functionality during the build process. Running the build script requires a Python environment. (Note, WhiteboxTools itself is pure Rust code.)

Depending on your system, the compilation may take several minutes. Also depending on your system, it may be necessary to use the python3 command instead. When completed, the script will have created a new WBT folder within whitebox-tools. This folder will contain all of the files needed to run the program, including the main Whitebox executable file (whitebox_tools.exe), the Whitebox Runner GUI application, and the various plugins.

Be sure to follow the instructions for installing Rust carefully. In particular, if you are installing on MS Windows, you must have a linker installed prior to installing the Rust compiler (rustc). The Rust webpage recommends either the MS Visual C++ 2015 Build Tools or the GNU equivalent and offers details for each installation approach. You should also consider using RustUp to install the Rust compiler.
