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 numbers to 5-4-2. 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: text data
Name: cname
Widht: 80

You can add additional attributes as columns with the button . The values of the attributes can be defined during the digitizing process.
