A quick tip: for higher quality hillshades (especially when zoomed in), make sure to also check "early resampling" checkbox in the layer styling panel...

Hi Hans, is it perhaps possible to use plugins from a new version 3.32 into an older version (mine is now 3.28) ? It always takes me so much time download & customize a new version and then re-install the plugins and add them to my toolbars New versions come out very often and I don't want to keep re-installing QGIS and go through the same process I would like to use the point cloud conversion plugins (from 3.32) as per your example but I don't know if that is easily done? I suspect there is an easier way to download a new version of QGIS and still be able to keep all toolbars and settings, perhaps an idea for a video ? Thanks for your great videos

QGIS installations share the location of your profile. Your profile stores your plugins amongst other settings. See kzitem.info/news/bejne/zoGKuHyCbot9nX4si=bCjHsy5H-h60jtMf. Only if your plugin is not supported by the QGIS version, it will not load. The point cloud tools in the video are core functionality, so you can only use those tools from 3.32.

Is this possible in QGIS 3.36.3 for Mac? Could you please advise how to proceed? I don't see the Point Cloud Conversion Tool in the tool menu.. Thank you.

You need to have pdal in your QGIS installation. The easiest on Mac is to install QGIS in a conda environment.

Thanks for such a helpful tutorial. I have two questions. 1. when you choose the Z attribute to create raster, is this Z value represent the ground elevation (DTM) or ground and objects elevation (DSM)? and 2. to analyse the slope, what would be the best suitable interpolation method to create raster (idw/TIN)? thanks a lot.

The Z attribute comes with the point cloud. If it's lidar, it's normally the first return number, which results in a DSM. If you want to have the ground, you need to use to filter. For example with the ground classification attribute. See this video on filtering: kzitem.info/news/bejne/la-mzoyeiWt0qXo. What is best to use for slope depends on the density and distribution of points. Best is to compare both results and choose the one that gives the best results.

@@HansvanderKwast Thanks a lots. it is so helpful. I am new to LiDAR data processing and love to play around it. Just find that the point cloud conversion tool is missing in my qgis. I am using 3.32 version on a Mac. do you have any idea? thanks

@@raiyans I'm not familiar with Mac. Probably you miss pdal. Alternatively, you can install QGIS on conda, which should work on all platforms.

@HansvanderKwast i was trying to filter out a point cloud by the Point Cloud expression, however i want to extract two bands (ground and wire conductor) but it is giving me error, i tried Classification = 2 AND 14 and Classification = 2 OR 14 but with no success, do you know if it isnt possible to extract more than one feature from the point cloud?

These tools are available since version 3.32 as written in the description of the video.
