Hi,
I am more interested to have a point in between rather than the triangles,
basically interpolate the data twice, to have an extra vertex between the
existing one.

Ho caricato un raster multibanda in qgis tramite
rasterLayer = QgsRasterLayer("/path/file.tif")
ho controllato il numero di bande tramite
nBand = rasterLayer.bandCount()
adesso vorrei potermi riferire a una particolare banda del rasterLayer,
tramite qualcosa come ad esempio

I am finding that after clipping a raster the resulting clipped file has no
scale. Or rather the scale says 0:1 and stays at 0:1 whatever the zoom
level.
This persists for all the map, whatever layers are on or off.
Can anyone help, please?
I am running 3.8.3 on Widows 10.

The main question is actually: why would you want to do that? You just end up
with a larger data structure (more triangles) to show exactly the same surface
model. You would not have any more detail, i.e the smaller triangles inside the
original large one would have exactly the same azimuth and
IMHO tension surface simulation for example can be an application where a
TIN up sample could be necessary

Hi Experts,
I've tried so many software's without success.
Is it possible to upsample existing TIN? What I mean is for example divide
each triangle into two for example. Not interpolation but somehow...
subdivide or add more vertices between existing one?
Thank you for all your time

I could easily be wrong, but I say I (and you) cannot
clip a raster layer. In the clip box the selections
for "Input layer" do not include raster layers.

*Hi QGIS users & developers !!!*
In layout, you can insert many maps (Add map), but only can be regular
polygons (square or rectangular), but when you want to create a special
presentation like a Tetris, you can't do it. The figures circle,
triangular, add polygon,... can't show maps inside them.

QGIS 2.18 support (as far as the QGIS project is concerned) ended in January

Hi,
I currently use Qgis 2.18. on Centos.
I would like to know if this will be supported and for how long?
We tried to upgrade to QGIS 3.x but there are backward compatibility issues.
Also there are dependencies issues.
Thanks,

This electronic message,
?? a point in between what? A TIN is a set of triangles, where each corner
represents an X,Y,Z point in space (on a surface usually). So where do you nwat
to have and extra vertex...? Sounds like you are not wanting aq TIN in the end,
but something else...

Hi,
You cannot invent new data between point without doing an interpolation. Your
choice of interpolation will determine the quality of this data. The only way
I can think of is to create a raster from this TIN. Then, resample
(re-interpolated) this raster with a finer pixel and then make a
I am trying to find a tool in QGIS that will allow me to calculate shortest
path between two layers (number of hospitals to number of addresses) using road
network data. There are two plugins (Networks and QNEAT3) and Network analysis
tools in Processing Toolbox but none of them allow me to
Hi,
I agree with Barend and Nicolas here.
It's a typical and essential question that we get all the time, like,
can we re-grid and subsample pixels ?
=>You can, technically, but you stay just within the same data,
and thus, create nothing new or meaningful.
In other words, it should not be done.
Hi
I have problem with Qtiles when I'm creating mapset (mbtiles file) . Tile
border breaks "point labels" when label cross the border between two tiles.
(no problem when point label is center of tile). Sometimes there could be
only part in visible for label on some zoom levels. When zooming in or
Hi,
Is there an all-paires options? If so, you can put the source and destination
in the same file and all possible source and destinations will be done. You
will then need to filter of what you don’t need. How many routes are you
dealing with?
I may have something for you but it’s not
