Changing pixel size

Often we need to change the pixel size (or spatial resolution) of a raster layer without changing the extent. The result of Up-sampling (or downscaling) are smaller pixels the result of Down-sampling (or upscaling) are larger pixels.

1. Click the Add raster layer and select a single band raster file with a spatial resolution (pixel size) of 10m.
2. In the processing toolbar, type Resampling into the search field to find the SAGA --> Raster Tools --> Resampling tool. Open it with a double click.
3. For producing larger pixels (100m) we use settings as shown in the screenshot below:

Click Run.

1. The temporary OUTPUT file may be saved on disk with right click on OUTPUT, Export --> Save as...
