- Under Settings Project → Properties set the SRS to the coordinate system GaussKruger Zone 3 (EPSG: 31467).
- Click the Add raster layer in the toolbar or choose Layer → Add raster Layer
- Navigate to ../geodata/multi_etm.tif
- Make sure the “Files of type” drop-down box has the “GeoTiff” filter selected.
- Double-click the multi_etm layer in the legend to oprn the Raster layer properties dialog.
- Create a false color composite.
- In the Symbology tab change the assignment of RGB to the band number 542. Change the standard deviation from 0.00 to 2.0 and press apply
- Create a new vector layer. Click Layer → New vector layer.
- Prepare the following window as shown below.
Type: Polygon
Type: Integer (whole number)
Name: cat
Widht: 3
You can add additional attributes as columns with the button 
. Choose the data “type” of the column (Integer). The values of the attributes can be defined during the digitizing process.
Save the Layer in your geodata folder, name it train.
