Chris, Thank you for your ideas. I am trying now, but there are some questions:
> For this, rather than use the Raster > Rasterize tool, the approach should be: > • open the processing toolbox Processing > Toolbox > • in the toolbox open Interpolation > TIN interpolation OK until this point > • in the TIN Interpolation screen: > • select the Vector layer OK. > • select the Interpolation attribute First problem: I stored the vector layer in a Geopackage; so I have an fid from the geopackage database, an ID from the original xyz-File in field_1, and the x, y, z values in field_2, _3 and _4. Which attribute should I choose? I think only field_2 and field_3? There is a checkbox for the Z-coordinate, whether I with to use it for interpolation. I guess I leave unchecked? > • click the + to add to the vector layer panel So I added the two fields, they are "Points" > • choose the interpolation method - probably best to use cubic > • click on the ... next to extent and set it to the layer extent OK > • set the pixel size to 5.0 and 5.0 OK > • click Run OK > This way you won't have the odd sizes you mentioned. This may give you a > smoother surface in the end as well. I started the prozess, but with more than 11 Million points, it seems to take too long, I am stuck at 50%. Will try later again.
