Always, always, always use graph paper for drawing sketch maps of O.S. maps or aerial photographs.

DRAWING A SKETCH MAP OF AN O.S. MAP

Drawing a sketch map to half scale. Use your ruler – measure the length and breadth of the map. Divide these figures by 2 and draw your sketch map to that size.

• MEASURE FROM HERE

• Not from here

EXAMPLE 24cm ÷ 2 = 12cm 18cm ÷ 2 = 9cm

Your sketch map will measure 12 cm x 9 cm.

Your sketch map must be the same shape as the O.S. map in front of you. E.g. this map is portrait so your sketch map must be portrait.
