Thank you for the answer. I will anyway not be able to use it because of missing information. </div>

I am also not sure if this tool is going to give me the result I need, which is the raster of a digital elevation model as a polyline. Is there a special tool for that? I only found an ArcGIS tutorial which uses its function "topo to raster" and I can't find
a similar tool in QGIS.</div>

<div dir="ltr">You can determine how the image resolution in two ways:
<div><br>
</div>
<div>1. Using the extent and the size of the pixels (which will calculate the number of rows and columns necessary), commonly named pixel resolution.</div>
<div>2. Using the extent and dimensions in rows in columns (which will calculate the size of individual pixels)</div>
<div><br>
</div>
<div>For option 1, you use the georeferenced units, and fill the next two options with the pixel resolution in the georeferences units, for example 10 x 10 m.</div>
<div>For option 2, you choose "pixels" and fill the next two options with the number os columns and rows of your output raster.</div>
<div><br>
</div>
<div>Maybe the documentation could be more clear.</div>
<div><br>
</div>
<div>Hope this helps.</div>

<p>Actually I red the documentation but I don’t know what you mean by „pixel resolution in map units“. There is only an Option to choose Pixel or georeferenced units. I tried both…</p>

<div dir="auto">The rasterize tool has two options.

<div dir="auto">Either use the number of horizontal and vertical pixels, width and height or the pixel resolution in map units.</div>
