I'm using a PC with 64 GB RAM.. hm, I would've expected that at least the scaled version works. Are you sure it is because of RAM or did I...

Simply like this: ```run\helios data\surveys\Paper\als_scenario_scaled_B_BR01.xml --lasOutput run\helios data\surveys\Paper\als_scenario_scaled_B_BR05_1.xml --lasOutput run\helios data\surveys\Paper\als_scenario_scaled_B_BR05_2.xml --lasOutput run\helios data\surveys\Paper\als_scenario_scaled_F_BR02_1.xml --lasOutput run\helios data\surveys\Paper\als_scenario_scaled_F_BR02_2.xml --lasOutput run\helios data\surveys\Paper\als_scenario_scaled_F_BR08.xml --lasOutput ```

Dear @Hannes9 yes, it is possible to define a MultiScanner as documented [here in the Wiki](https://github.com/3dgeo-heidelberg/helios/wiki/Scanners#multi-channel-scanner). So for your application, you would add a new scanner to `scanners_tls.xml`, which has...

Ah yes, of course, I should have recognized the multi-channel scanners :D You can have a look at the velodyne scanners in [scanners_tls.xml](https://github.com/3dgeo-heidelberg/helios/blob/dev/data/scanners_tls.xml) which show how to orientate the different...

Not better, just a bit easier to debug I guess

Hi Hannes, yes, that sounds like a likely explanation. If your platform is not at the same XY-location as your scenepart with the `helios_isGround` parameter set to true in the...

Ah sorry, I confused it with ground positioning of the scene parts, sorry You're right. For the platform, HELIOS++ determines the ground as the lowest z-coordinate in the scene data...

Did it work before replacing z values by the `onGround` parameter?

Is it correct that you want the scanner to rotate? If so, I guess you want it to rotate continuously, not just on 360° rotation? Can you try setting the...

Hi @jeremy-fgn, there is nothing wrong with the survey file. For me, it works when I remove the comment from the `platform.xml`, right in line 2. I am not sure,...
