A quick tip: for higher quality hillshades (especially when zoomed in), make sure to also check "early resampling" checkbox in the layer styling panel...
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: ruclips.net/video/4yphXhP9CvE/видео.html. 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
Hello. I have a question for you. How do you interpolate large pointclouds without (A) having RAM shortage and ending the process unexpectedly (B) interpolating sub datasets each time and then merging all the rasters without having artifact issues on their borders?
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 ruclips.net/video/mKTRHL5YLjI/видео.htmlsi=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.
Hi Hans I have qgis 3.22.16 Version installed in my computer, but I am unable to see this point cloud tools in processing tools bar Is this an external plug-in ?
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.
Very helpful, thanks!
Great thanks 🙏
Great 😊

@@raiyans I'm not familiar with Mac. Probably you miss pdal. Alternatively, you can install QGIS on conda, which should work on all platforms.
@joaopereira9306 You should repeat the expression after AND or OR, so it reads Classification = 2 AND Classification = 14

These tools are available since version 3.32 as written in the description of the video.
Thanks a lot did not see your discription before

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