Maps
SATELLITE IMAGE
Space satellites are used to
photograph Earth, capturing its
surface in great detail. Orbiting
thousands of kilometres above
the planet, satellites track
changes in the land, the ocean,
and the atmosphere.Maps provide visual representations of the world,
revealing the layout of our planet in a variety of
ways. Some depict Earth’s geographical features,
or the borders and boundaries between nations.
Other maps detail road routes and street names,
or aid navigation on urban transport networks.
Scales on maps can be used to work out real
distances, and keys explain map symbols.208
STREET MAP
Useful tools for navigating
cities and towns, street maps
include road names and
notable landmarks such as
railway stations, hospitals,
churches, and parks. Street
maps are available online and
via some mobile phones.BUILDING PLAN
When planning a new
structure, engineers first
map out the building.
Details such as layout, walls, and
entrances are marked to assist
workers during the construction.
Precise measurements are added
to give the true size of the project.208-209_Maps.indd 208 03/01/19 12:11 PM
