[Qgis-user] traitement "nuage de points LIDAR"

[Frank Broniewski]

This processor is far too old to be used with any kind of GIS. It dates from 2008 and has only one core with 1.6GHz. It was never performant even when it was released in its day ...

Dear Georges,

Windows 7 is not supported anymore by QGIS. Windows 10 should still work, but only in 64bit mode. We phased out the 32bit Windows version.

In general - to display and process point cloud data we recommend a recent and fast machine with sufficient RAM. For 3D display a good graphics card (OpenGL) is recommended.

Hope this helps,
Andreas

Hello,

I own 2 “eMachines EL 1600” computers (Intel ® Atom ™ CPU 230 @1.60GHz ) one with “Windows 7 home” operating system, the other with “Windows 10 professional”.

I can't install the latest versions of QGIS.

Message displayed: "This installation package is not supported by this type of processor. Contact your reseller".

However, I was able to install QGIS 3.18.3 Zürich, to which I added the “LAStools” extension.

I wanted to use the “point cloud” files provided by the "https://geoservices.ign.fr/lidarhd" site, named "LHD_FXX_????_????_PTS_C_LAMB92_IGN69.copc.laz", but they didn't seem to be taken into account when I added them (“Open Data Source Manager” -> “Point Cloud” -> "..." (Browse) -> “Add”.

Are they not recognized by this version of QGIS? Is this a mistake on my part? Or are other extensions missing?

Please do not hesitate to contact me should you require any further information. Thank you very much.

Bonjour,

je possède 2 ordinateurs “eMachines EL 1600” (Intel ® Atom ™ CPU 230 @1.60GHz ) l'un avec le système d'exploitation “Windows 7 familiale”, l'autre avec “Windows 10 professionel”.

Il m'est impossible d'installer les dernières versions de QGIS.

Message affiché: "ce package d'installation n'est pas pris en charge par ce type de processeur. Contactez votre revendeur".

Par contre j'ai pu installé la version QGIS 3.18.3 Zürich auquel j'ai installé l'extension “LAStools”.

Voulant exploiter les fichiers “nuage de points” mis à disposition par le site "https://geoservices.ign.fr/lidarhd" nommés sous la forme: "LHD_FXX_????_????_PTS_C_LAMB92_IGN69.copc.laz", ces derniers semblent ne pas être pris en compte au moment de les ajouter ("Ouvrir le Gestionnaire des sources de données" -> “Nuage de points” -> "..." (Parcourir) -> “Ajouter”.

Ne sont-ils pas reconnus par cette version de QGIS? Est-ce une erreur de ma part? ou manque-t-il d'autres extensions?

Me tenant à votre entière disposition pour toutes informations complémentaires et en vous remerciant, cordialement.

Georges MARESCAUX
