1. CONTOUR LINES
Contour lines of 5 metres intervals are used to identify detail. Even names of places,
railway lines and roads are shown on the photo. The objects are therefore easily
identifiable. Maps and photos therefore have their own characteristics, advantages and
disadvantages. A clear presentation of a landscape is only possible when using a
topographic map and photo together.

Hill
A steep slope has contour
lines close together.
A gentle slope has contour
