  1. Click the Open Data Source Manager QGIS 3.0 datasource.png and then Add raster layer QGIS 2.0 addrast.png. Select the single band raster file /geodata/lucc/s2/Subset_S2A_MSIL2A_20170619T_B2.tif.
  2. After clicking Add, Close the raster layer appears on the QGIS canvas.
  3. Right click the layer name in the Layers Panel and select Properties --> General. Report on the spatial reference system, size (columns and rows in pixels) and if a specific No-Data value is assigned.
  4. Choose Properties --> Information QGIS 2.0 metadata info.png. In the "properties" window scroll down and have a look on univariate descriptive statistics such as minimum, maximum, mean and standard deviation. If statistics are not shown for all bands 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.
  5. Report on:
    • Pixel size
    • No Data Value
    • Data type
    • Layer spatial reference system
    • Layer extent (Xmin, Ymin, Xmax, Ymax)
