Changing pixel size
From AWF-Wiki
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.
- Click the Add raster layer
and select a single band file C:/OSGeo4W64/geodata/raster/s2/Subset_S2A_MSIL2A_20170619T_B03.tif. This is the spectral green band with a pixel size of 10m.
- Click Open, and the raster layer appears on the QGIS canvas.
- In the processing toolbar, type Resamling into the search field to find the SAGA --> Raster Tools --> Resampling) tool. Open it with a double click.
- For producing smaller pixels (5m) we use settings as shown in the screenshot below:
Click Run.
- For producing larger pixels (100m) we use settings as shown in the screenshot below:
Click Run.
