Using SRTM data this way doesn't help to depict the vectors in 3D

<p>Hi Saber,</p>
<p>ok will the clipped Boulder data be suitable for the 3D dataset
that we want to provide in the qgis sample data?</p>
<p>I wonder if srtm data will have a good resolution. Will you
also clip a srtm dataset for usage in the qgis sample data?</p>
<p>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!</p>

<div>I was clipping the Boulder data to something manageable.
But if you have moved to NY data, that should be fine too.</div>

<div>In terms of the underlying terrain, we have a

<div>Usually the z-scales in terrain and buildings do not line
up nicely, therefore I thought it is better to have 2
different sections: one on terrain (rasters) and one on
buildings (vector).</div>

<p>Hi Saber,</p>
<p>I switched the location and prepared a geopackage with
the 3D data of new york.</p>
<p>I think your blog should be updated as I still only can
depict a flat plane of the data in the 3d view tool.</p>
<p>Sorry for bothering but it's my task to write about the
3D settings in QGIS 3.10 ...</p>
<p>Cheers, Larissa<br>

<p>Hi Saber,</p>
<p>thanks for giving me the hint. Do I need to add a
raster layer with height information like geoTiff
(SRTM data etc.)</p>
<p>in order to define the position of the 3D buildings ?
I got this information in a presentation on youtube.
Right now, after</p>
<p>defining the single symbol of walls and roofs (data
city of Boulder), there is only a plane :-(</p>
<p>Cheers Larissa<br>

</div>
<div>Apologies. Boulder data indeed contain walls
and roofs. </div>
<div><br>
</div>
<div>To view the data in 3D, you need to go to each
layer and open Properties > 3D view and change
the style to Single symbol.</div>
<div><br>
</div>
<div>Also, the dataset is very large. It would be
easier if you crop the data to a smaller area.</div>

<div>Many thanks for looking into documenting
this.</div>

<div>I had a quick look at the data. It is only
the footprint. So, you can only extrude the
data (based on height). </div>
<div><br>
</div>
<div>There is a good data source of 3D buildings
here:</div>

<div><br>
</div>
<div>And for building in New York, we wrote a
blog post here. The data have z-valuse and
should automatically get picked up by the 3D
map view.</div>

folks,<br>
<br>
for documentation purposes I'd like to
visualize the 3d data of the city<br>
of boulder in qgis 3.10 .<br>
<br>
<a
href="https://bouldercolorado.gov/open-data/city-of-boulder-3d-buildings/"

moz-do-not-send="true">https://bouldercolorado.gov/open-data/city-of-boulder-3d-buildings/</a><br>
<br>
Unfortunately qgis crashes when loading the
shapefile into the 3d view.<br>
<br>
Also, where do I have access to the
z-coordinate so that there will be a<br>
3d view. At the moment there is only visible a
plane with the vectors<br>
but no "z-value" in the 3d view application.
Extrusion doesn't help<br>
solute the problem.<br>
<br>
There is a hint that these data have something
to do with GeoJSon, so<br>
maybe I have to find another 3d data suitable
for using in the 3D view<br>
application.<br>
<br>
Can somebody help?<br>
<br>
Cheers, Larissa<br>
