- Click the Open Data Source Manager
and then Add raster layer 
. Select a single band raster file.
- After clicking Add, Close the raster layer appears on the QGIS canvas.
- Right click the layer name in the Layers Panel and select Properties --> Information. Report on the spatial reference system, size (columns and rows in pixels) and if a specific No-Data value is assigned.
- Choose Properties --> Information
. In the "properties" window scroll down and have a look on univariate descriptive statistics such as minimum, maximum, mean and standard deviation. If band statistics are not shown go to Properties --> Histogram and click Compute Histogram. If layer extents are not shown go to Properties --> Metadata --> Extent. Click Set CRS from Layer and then Calculate from layer.
- Report on:
- Pixel size
- No Data Value
- Data type
- Layer spatial reference system
- Layer extent (Xmin, Ymin, Xmax, Ymax)
