Satellite photographs

Without the Web, the satellite photographs of the affected zone wouldn t have been shown publicly, people wouldn t have been coordinated quickly to act as volunteers in the most affected zones, information wouldn t have gotten to the volunteers about how to handle the sludge he said. Definitely, the (role) of the Internet has been decisive. (Scheeres 2002)... 

Until recently very little research work had been carried out to determine the relationship between plant cover in the area and the regional or global characteristics of the atmosphere. Our work has been developed in the Amazon region and we have tried to establish the relationship between the present climate equilibrium and the dense forest cover which extends over an area of more than 5 million km The research was carried out in successive stages, involving analysis of surface meteorological data, radiosonde data, satellite photographs, and analysis of chemical and isotope composition of rain water. 

At the surface of the open sea, a tsunami is not noticeable because it is spread over such a large area. As the wave passes over the sea, it may displace the water only a few feet. Since wave crests created by a tsunami are widely separated, ships at sea rarely notice the traveling water. From an airplane or in satellite photographs, such a wave is virtually invisible.

We already know that the blue band is always eliminated when aerial or satellite photographs are taken from high altitudes. This does not apply on the ground, where scattering is negligible due to the lesser amount of atmosphere between the camera and the object photographed. 

These are the most familiar. Most television transmitters, for instance, broadcast a satellite photograph to illustrate the announcer s commentary in the weather forecast. Indeed, research studies are so plentiful that it would be impossible to select a brief bibliography.
