The representation of the Earth: maps
In the past, cartography (or map making) was a very slow process. It involved observation and complex calculations and drawings. Modern maps are made using aerial photos and images from satellites orbiting the Earth. To map a large area, many of these images are put together to produce an exact picture of the planet's surface. Maps help us check our location and find our way around. [...]

The graphic scale of maps allows us to calculate the real distance between two places. We do this in the following way: Find two points on the map between which you want to know the distance. [...]
