To open the OS VectorMap District (Raster) format Select ‘Add raster layer’ (see below)

To restore the image to its original view right click on the raster image layer and click ‘Zoom to layer’.
The map is most functional for scales 1:15 000-1:30 000. For this tutorial we want a map of an area of Southampton at a scale of 1:17 000. Use the ‘Pan tool’, ‘Zoom in’ and ‘Zoom out’ to position the map over Southampton at an appropriate scale, or alternatively set the scale of the map by typing in the scale bar, which is at the bottom of the screen.
