Opening OS OpenData in QGIS

Open QGIS from Start>All Programs>QGIS Brighton>QGIS Desktop 2.6.1

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

Click ‘Browse’ and navigate to the downloaded files that have been extracted. Select the required TIFF files. In this case SU41 is the required image. Click ‘Open’.

The opened map will look similar to this:

Once open you can move about and investigate the map using some of these tools:

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.
