Hi,
I am testing the GDAL tools the way you explained, but I still get artifacts.
When I say artifacts, I do not mean pixels, I know what pixels are since I
started using a scanner nearly 30 years ago, I think of sudden jumps in the
lightness, which leads to lines and grids in the raster

I have two layers: "Bus routes" and "Bus stops" with a common attribute
"Sampled_Route".
As many bus routes drive on the same road a lot of features are on top of
each other. I will like to be able to "Scroll through" my data for QA using
the Go2NextFeature plugin and only show the selected bus

Dear Alexander,
Thank you for looking into it. As I said, there is no projection on the fly, my
layer and the file are in EPSG:6670, as is the project.
I will try with a selection from the large layer today!.
Best,

Hi all,
This topic comes up every couple months, dating back almost a decade or
two. If you google for "QGIS nircmd virus" you will find plenty of
discussions around this topic, like this discussion thread from 2011:
I’ve done what you described – select a point away from the edge and manually
adjust the observer height. This does work.
I also tested negative observer height. If it is surrounded, the viewshed
simply shows nothing (neighboring pixels only).
However, I’m going to be doing 100+ points
You could try converting the first lidar returns to a raster layer and using a
negative elevation observer value or select point that is one or 3 pixels away
from the edge of the roof. I am not sure if the negative observer height will
work but it may. If you need to remove obstructions, you
Dear QGIS mappers,

Hi,

As you can see, it could be very useful to use if one wanted to hack a
computer. My guess is that it gets flagged because the company also

Hi Nicolas,
I just noticed https://github.com/qgis/issues/32247 that was just posted
today. It seems that Trend just updated their virus database, so there
could be troubles ahead for QGIS users.
I was afraid our IT department would blacklist QGIS. This ticket was

Hi Nicolas,
yes, I know, but I find QGIS definitely more user-friendly than SAGA and QGIS
helps quite a lot in easing the handling of projections and the I/O process, in
my opinion.
Nevertheless, it turns interesting to know how to do it also because, in case,
it can be added to the main qgis

More info...
You can select the points you want to change manually or by using an expression
“class” = ‘D’.

in the processing toolbox.

If the project is in one CRS, and the layer is in another, then the raster
is transformed on-the-fly for sure.
Give it a try.

At least, 4 things can go "wrong" between QGIS and postgis views, which
result in the yellow warnings.
1 - theres no "id" column or it has repeated values;
fix it or create a identifiers on the fly with rownumber() over() as id
2 - QGIS was not able to guess which column to use for unique
I don't know.
That issue has been around a while:

As far as I know, the yellow triangle means that either something is

It basically means that the layer can't be loaded, unless the user
