About

My name is John Lindsay, a professor of Geography at the University of Guelph, in Canada. My research interests include geomorphometry (digital terrain analysis), applications of LiDAR, surface flowpath modelling, and spatial analysis more generally. I am also a keen supporter of open-source geographical information systems (GIS). Over the last several years, I have been the lead developer of a cross-platform free and open-source GIS called Whitebox Geospatial Analysis Tools. This blog highlights some of the interesting developments and applications of Whitebox GAT. Feel free to leave comments and if you have any question, send me an email.

    Can you kindly provide a shord description of the capabilities to display the Lidar data in 3D, in fusion with raster elevation data rendered in the same view?
    Is there a possibility to view in 3D and interact, for example: measure the highest point in a selected area (in 3D) or edit the point cloud?

    Hello Mr. Lindsay,
    i have read your chapter about “Modelling Channelling and Deflection of Wind by Topography” and would like to reproduce it in Whitbeox GAT. But while trying to use the script delivered in the chapter i have encountered some problems and would be very thankful if you could support me solving these issues, maybe there already exists a tutorial about the CDI for your students or we can get in contact via e-mail.

    Looking forward to your reply,
    Simon Ehrensperger

    • Hello Simon,

      The tool described in that book chapter was actually developed for the software package that was Whitebox’s predecessor, the Terrain Analysis System. Most of the functionality of TAS has been replicated in Whitebox, but in this case, I’m sorry to say that the wind exposure algorithm has not been transferred into Whitebox GAT. Whitebox does not share the same scripting language with TAS, which was a domain specific language. It is still possible to carry out this type of analysis in Whitebox but it is a fairly convoluted method. If you are still interested, please send me an email and I’ll see if I can help.

      Regards,

      John
