aerial photography的意思|示意

Aerial photography, also known as \"remote sensing\", refers to the use of a camera mounted on an aircraft or spacecraft to take photographs of the earth's surface from an altitude. Aerial photography has a wide range of applications, ranging from mapping to surveillance to disaster monitoring and management.

In mapping, aerial photography has been used for centuries to accurately capture images of the earth's surface and to precisely determine the coordinates of points on the land, sea or ground. With the development of satellite technology, aerial photography has become even more precise and reliable.

For surveillance purposes, aerial photography is used to monitor and detect suspicious activities or changes on the ground. It is also used to survey the terrain and to plan the construction of highways, bridges, dams and other infrastructure.

Aerial photography can also be used to monitor the impacts of natural disasters such as floods, fires and earthquakes. Images captured by aerial photography can be analyzed to determine the extent of damage and to plan the best course of action for recovery and reconstruction.

Finally, aerial photography is also used in archaeology to study ancient sites and structures, as well as to document changes in the environment over time.

Overall, aerial photography is an invaluable tool for scientists, engineers and other professionals who need precise and accurate images of the earth's surface from an aerial perspective. It can be used for a wide variety of applications, from mapping and surveillance to disaster monitoring and management.
