Hei!
As far as i remember from the courses i took in remote sensing (And i don't
find any reason to believe that QGIS would have a different theory):
- The Residual error is calculated for every GCP( between the expected
coordinate and the actual location).
- Then the total error is
Hi Todd,
Bear in mind that the conda installation from conda-forge, which is not
officially supported by QGIS.org, is missing support for QtWebkit. This
limits its usage in many aspects, including the 3D viewer and some very
nice plugins.
It's a long-known issue, but no one was able to fix it so
Hi,
As far as I know, the residual column represents the difference (distance
in map units) between the GCP coordinates and the place where that image
position ended up after the georeferencing process. So, yes, it represents
the error for each GCP.
To calculate the total RMSE, I think you have
Hei!
I think v.clean can fix up topological errors. Tweaking the parameters should
get you there

A little bit older tutorial but i think it still might work.

Greetings,
The relevant code is located here

Hope this helps.

Hei! Thank you for the answer!
I presume everybody would like the same functionality as i wish to have.

Good afternoon QGIS People
I received a question on RMSE errors in georeferencer and after talking
to Ethan about it I realized I have no clue what I'm talking about. How
would we go about calculating an RMSE for a rectified image in QGIS?
I've cc'd ethan on this so he can chime in also.
Dear all,
The attached shape has multiple topological errors and I would like to know
how to remove all of them.
First, I dissolved the shape PalancaresERTS89 and checked topology and
found multiple errors inside the poligon. I would like to know the way to
remove all the errors. I am aiming to
I stand corrected, there is a backgrounds/background_square.svg included in
the default svgs, so you can probably just use that and adjust the width to
height ratio to get the desired effect.

I would suggest using an embedded SVG marker, for which you can set data
defined properties for width and height.
I don't think there is a straight line/ block marker, but you can
probably find one somewhere using the resource sharing plugin.
Alternatively, you can make a custom SVG in inkscape
Hi,
I have a trajectory of a vehicle (= a list of points including heading, crossfall, slope, curvature, radius, ...) and would like to visualise the crossfall. Per point there should be a line pointing left or right (transverse to driving direction) with the line having a length according to the

Actually I found myself in the same situation on a test box this
morning. Has there been any movement on this - I think QGIS 3.16, QGIS
3.10.11, Ubuntu 20.10, etc all happened on one day or close to it.
Ubuntu 20.04 updated smoothly to 3.16.

Hi Robert,
This has been asked before. I think currently this option only redraws
the layer and does not (always) refresh the data. At least not for a
remote layer.
It has been discussed before here:
https://lists.osgeo.org/pipermail/qgis-user/2020-April/045348.html
and here:
Ah, and to reproduce, I created a temporary(!) service:
https://duif.net/geotest/points.geojson
which gives you one random point on the world every time you refresh

Not sure if I can tackle it, but I can give it a try.
If a core-dev has a clue, please let me know...
I think this should work, as this makes it supereasy to have a 'moving
Hi Robert,
I do not know the answer to your question, but I think you are asking in
the wrong list.
You may have better success on `qgis-developer` (I added it in, so this
is getting cross-posted)
