Landscape chambers: a new method for (cognitive) landscape analysis.
Insight: landscapes are composed of specific spaces, such as mountains or valleys. Problem: how to delimit such spaces ?
Below: a non-trivial topography (Puy-de-Dôme, France) and modelled landscape areas.

After making a massive $7.19 in 4 months (less than the $10 payout threshold), I've decided to start ungating my Medium-hosted tutorials (it's not really in the knowledge-sharing spirit anyway!) and migrate them to my website, starting with... https://t.co/MxMHuiz0Hq

🔵💃📊 Dernier tango pour l’indigo

Lorsque l’indigo arrive en France au XVIe, il est tout de suite perçu comme une menace pour un autre colorant bleu, bien français celui-ci : le pastel.

Qui sortira vainqueur de cette valse des colorants ? N'insistez pas je vous le raconte ⬇️

Super cool 🤓🤓 : animated shadows in #QGIS. Made with Terrain Shading plugin, with a help of a dedicated script (London city Lidar data).
plugin : https://t.co/Z4w4da2bYL
script : https://t.co/GbZAwpbb8r
The script is bare bone Python - but not excessively technical, I hope...

@aramco Business as usual...

Richard Edes Harrison (1901-1994) made maps that radically changed our world view. As chief cartographer for Fortune Magazine, Harrison developed mapping concepts later found in GIS, data visualization, and thematic cartography. See 142 of his maps: https://t.co/T75e3bl5G1

Using #RStats and #QGIS and working on Linux? You may want to try https://t.co/3Hxnlbf8SG C++ plugin to run R inside QGIS. Allows seamless integration of R with QGIS. The initial work on this was done by @nyalldawson. The plugin needs to be compiled locally to work.

#GDAL Pro Tip: gdal_viewshed command can do visibility analysis using elevation datasets. Here's an example taking the 1m resolution DSM of London to determine all areas that will be visible from the top of the Tower 42 building. https://t.co/KG4wRlU3hp

There's a new programming language in town - it's Mojo! I'm more than a little excited about it. It's Python, but with none of Python's problems.

You can write code as fast as C, and deploy small standalone applications like C.

@KhoaVuUmn ... and you can reuse the code :)

Dans mon grenier je viens de retrouver une machine à calculer #Curta. A coup de manivelle on peut additionner, soustraire, multiplier, diviser avec ou sans virgule ! C’est génial ! Qui connaît ?
