Recents works


One year after the T3 contest, here are some works from this year and a review of the new tools that we learn to use.

I am still working with Canon S100 and dronemapper intervallometer script, all multirotors are now controled by Pixhawks, the flying wing is controled by an APM 2.5.2

New open sources tools for DEM visualisation :

Visit 2.8.2  (above)

You can get it here :


Really good for generate colored shaders and contours and for very-micro-reliefs analyses



Relief visualisation toolbox

RVT from Dr. Žiga Kokalj - 2014

Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU)
Centre of Excellence for Space Sciences and Technologies (Space-Si)

Here is an exemple of multiple-direction shader (16 directions) at Commes (France) for CNRS and INRAP :


Somes works from this year :

Jardeheu (France), 5cm resolution :


Fleury-sur-orne (France), INRAP

Medium neolithic necropolis, 4cm resolution :



Detail of a small neolithic Tertre, 1cm resolution :



Orthophoto and DEM of a very big Tertre, 1cm resolution :

  • T3

    Yes, just called HSV Shader.

  • Great thanks Sylvain. Is the rainbow colors ramp shader also in Global mapper? It's very nice.

  • Sorry, you're right

  • T3

    There are no multispectrals images in this exemples, only DEM analyses and visualisations

  • Beautiful images and processing.

    So, how did you manage to have NDIV data? Did you change S100 lens? 


  • T3

    It's a HSV Shader from Global Mapper, a rainbow colors ramp shader and a light from azimut 80.

  • Do you mind me asking which software you used for the small neolithic Tertre, 1cm resolution multishading?

  • thanks for the Visit link, a nice and inspiring tool for 3d visualisation.

    and also congratulation for good work !

  • T3

    Agisoft Photoscan Pro

  • These really are exquisite examples of power of visualization tools. Remind me, what software are you using to generate the DEMs? I realize you've probably said before, but I didn't search for prior posts. Thanks for sharing these.
