<p>Hello Nikos:</p>
<p>Here are two options to get you started.</p>
<p>QGIS has a front-end to the GDAL utility GDAL_grid under the
"Raster ->Analysis" menu, there are four GRID* options. You
would do well to first read the GDAL grid tutorial:</p>
<p><a class="moz-txt-link-freetext" href="https://gdal.org/tutorials/gdal_grid_tut.html#gdal-grid-tut">https://gdal.org/tutorials/gdal_grid_tut.html#gdal-grid-tut</a></p>
<p>to choose the best method for your case.<br>
</p>
<p>These interpolation options are not the best, so your results
will depend on the density of the points.</p>
<p><br>
</p>
<p>A second option is the GRASS tool, v.surf.rst under "Processing
-> GRASS -> Vector". This tool uses spine interpolation, and
offers some configurations to the smoothing procedure, so it's a
bit more complicated. But it often gives better results. <br>
</p>

<p>HTH, Micha<br>

Hi all,
<br>
<br>
I use QGIS 3.14.16 on WIN10.
<br>
I have a shp file of points. For each point I have the height in
meters. I would like to make a DEM out of it.
<br>
How can I do it? I tried to find something in QGIS 3.16
documentation but didn't help.
<br>
Any ideas?
<br>
<br>
<br>
Thank you very much
<br>
Nikos
