[Qgis-user] raster layer and vector layer ---> create 3D view from it

Hello Saber,
in the meantime I used New York 3D data to check out the 3D view tool.
Using the hints of your blog I'm having
* a Buildings_3D_Multipatch layer from a
DA10_3D_Buildings_Multipatch.gdb (vector layer)
* SRTM data N40W074.hgt (raster layer)
now.
Next steps:
* the srtm data in the 3D view tool: Type = DEM (raster layer) ,
Elevation = N40W074
* single symbol setting in the 3D view properties of
Buildings_3D_Multipatch
Using SRTM data this way doesn't help to depict the vectors in 3D (I
thought the srtm data have the function of a master). Do I have to
convert file formats?
I'm using QGIS 3.10.2 and win10.
Cheers, Larissa

Hi Saber,
ok will the clipped Boulder data be suitable for the 3D dataset that we
want to provide in the qgis sample data?
I wonder if srtm data will have a good resolution. Will you also clip a
srtm dataset for usage in the qgis sample data?
Then I would of course prefer to use this data so that a user can
quickly check out the usage of the 3D view functionalities!
Cheers, Larissa (-:
