<p>Hi Sämi,</p>
<p>Unfortunately this is not yet implemented.</p>
<p>I see two different approaches on how to get this information
from the sensor to the data<br>
</p>
<p>- Expose it as a variable (@positioning_accuracy) to the
attribute form. The attribute form will need to be configured, so
this information is saved to a feature (via default values). <br>
</p>
<p>- Save this information to the m value of vertices. For this to
work, the dataset has to be a format that supports m values. It
could then also be extracted with m($geometry).</p>
<p>The approach with m values has the approach that it works
perfectly fine for line geometries as well. An accuracy value can
be saved for each vertex. The approach with @variables on the
other hand is on geometry level and not on vertex level.
Therefore, this would need to save this information into an array
for lines. So if a vertex is deleted on such a line later on, the
information is corrupted easily. On the other hand, it has the
advantage that several values can be saved like other data coming
from positioning sensors (like speed) or from external sensors.
Whereas with m values there is only space for one single value per
vertex.</p>
<p>Personally, I tend towards the variable/attribute approach.<br>
</p>
<p>Kind regards<br>
Matthias<br>
