Everything You'll Have Covered

What is remote sensing?

~ Remote sensing is the ability to create, with technology, a map of an area without having to physically be in that area.

How does remote sensing improve our mapmaking ability?

~ Remote sensing improves our mapmaking ability by allowing us to capture a level of detail greater than our naked eyes can perceive.

How does remote sensing work with satellites?

~ In remote sensing, satellites catch light rays reflected from the surface of the Earth, some of which are visible to the eye and some of which are not. The satellites then send information about these light rays to computers back on Earth. These computers then process the data from the satellites and use it to construct a photographic image of a certain region.

How does satellite imagery help today's mapmakers?

~ Satellite imagery helps today's mapmakers to identify land features such as volcanoes, glaciers, arable land, cites, seas, lakes, deserts, and cultivated areas with great accuracy. It also allows mapmakers to observe erosive features such as deltas, valleys, and disasters such as floods and earthquakes.
