John Lindsay, the main developer of the little known but extremely powerful GIS program Whitebox Geospatial Analysis Tools, describes his software at GISRUK 2014 in Glasgow.
3. http://www.uoguelph.ca/~hydrogeo/Whitebox/
• Origins in the Terrain Analysis System (TAS)
• Whitebox GAT project started in 2009
• Free and open-source GIS and remote sensing
software package
• Google code repository
• Multi-platform software
• Translated into 11 languages

4. Whitebox
• Currently contains 372 tools for processing DEMs,
raster images, vector data, and LiDAR.
• New tools can be added as plugins developed using
any JVM programming language (Java, Groovy,
Python).
• Useful as a powerful geoprocessing engine

6. Terrain Analysis Toolbox
• Tools for extracting information
from DEMs.
• Surface derivatives (slope, aspect,
curvature)
• Hillshading and visibility analysis
• Relative landscape position
• Landform classification
• Topographic index, sediment
transport index, etc.

7. LiDAR represents the state of the science for
topographic and canopy mapping.

LiDAR Toolbox
8. LiDAR Toolbox
• Whitebox contains tools to
– interpolate LAS files,
– mosaic tiles,
– fill in missing data gaps,
– remove off-terrain objects
– model vegetation canopy

14. Stream Network Analysis Toolbox
• DEM-based automated stream
mapping
– Algorithms based on either valley
recognition methods (i.e. DEM
shape) or channel initiation
methods (i.e. contributing area
thresholding)
• Link length and slope
• Stream ordering
• Long profiles
• Link classification

16. Whitebox as an ‘Open-Access GIS’
• The potential benefits of O-S GIS include wider community
involvement, deeper user knowledge, and rapid innovation
in the field.
• The intention of O-S GIS is good but we could realize even
more benefits if we altered the implementation.
• The potential benefit of OSS is often defeated by the
barriers that are in place as a result of the implementation
of the O-S model.
• Open-Access GIS: software should be designed in a way
that reduces the barriers that often discourage or disallow
end-users from examining the algorithm design and
implementation associated with specific geospatial tools.

21. Concluding remarks
• Whitebox provides extensive tools for
extracting information from spatial data sets.
• The open-source(access) nature and ease of
use of Whitebox provides an ideal
environment for education and research.
