Hi, thanks ! can you generate 3D roof from this (as meshes) ? (or raster heightmap ?)

Nice demo. I was looking for how to colorize LAS data, found info on the Whitebox QGIS plugin and installed that, and then found this video as a tutorial. It really made things a lot easier, and you pointed out some extra features like blocking out water, which had low quality edges. Now I know to also install the "Quick OSM" toolset. QGIS has come a long way in the last 5-10 years!

Impresive, finally a way to colorize point clouds with rasters!!. One question theo the Ambient Occlussion i mesh only tool? isn´t a way to do so with point cloud?. Cloud Compare can, but has artifacts on the edges where it gets too bright.

These data do not support “ stopping the download and then starting to download“ I have downloaded failed because of the net speed. Which area of the original site map is this data?

Hi Hans, apparently, my point cloud of the Ardeche River (France) has not projection. Is there a way to know which one is relevant for my specific location to use in qGIS?
@HansvanderKwast Жыл бұрын
First you should check if the point cloud is in the national projection for France. If that's not the case, try if you find the projection by seeing if it shows up correctly on a backdrop of an online layer, e.g. OpenStreetMap.

Thank you for the helpful demo! Do you know, if after the application of the LidarRooftopAnalysis tool the field AREA is supposed to be an area of a sloped segment or just an area of a projection of points identified as a segment on the horizontal plane of building footprint geometry?
@HansvanderKwast7 ай бұрын
I did a check and it was what I was expecting: it is the area of the polygon geometry (I tested by using $area and it's almost the same - rounding differences).

Hello! Can you redirect me to the video where you said you converted LAZ to LAS? Thank you!

Hi there. Did you find this out??? I have tried using the LazToLas tool from Whitebox but it keeps asking for the location of the LAS file which is a bit counter productive as its the LAZ file that needs to be found to turn into a LAS lol

What does it mean "whitebox_tools" is missing?
@HansvanderKwast Жыл бұрын
WhiteboxTools is a processing provider plugin. This means that you need to install both the WhiteboxTools software and the plugin. In your case, the plugin couldn't find the WhiteboxTools software. Here you can find the instructions to use the WhiteboxTools plugin: www.whiteboxgeo.com/manual/wbt_book/qgis_plugin.html
