Using maps in association with photographs and field sketches
In addition to an OS map, mapping questions include supplementary sources of information. As well as graphs and tables of data, you can also be presented with photographs and/or sketches. You should be prepared to link these to map evidence and use your knowledge and understanding to interpret all the information provided.
Cross sections/transects and OS maps
You could be asked to study a A shape or surface that is shown as the result of cutting through it in half, so that the inside can be seen, eg a cross-section of a river or of a mathematical shape. on the OS map between two points, usually six figure grid references.
To answer this type of question it is useful to use a pencil to draw the cross section line on your OS map. You can then work out each land use as it appears along the line from A to B.
