Satellite images are powerful and essential tools used by meteorologists to determine the behavior of the atmosphere. They provide a clear, concise and accurate representation of how weather phenomena unfold.Know More
The CIMSS states that satellite images provide a good representation of what happens everywhere around the world, particularly over oceans where large data gaps occur. It improves forecasting accuracy by allowing meteorologists to understand atmosphere behavior much more clearly. The two types of satellites orbiting the Earth are the geostationary and polar satellites. Geo Graphical Stationary Operational Environmental Satellites stay above a fixed region on the Earth's surface, around 22,500 kilometers above the equator. These satellites always view the same part of the globe, as they rotate with the Earth, allowing meteorologists to see how the weather develops. In contrast, the polar orbiting satellites orbit at lower elevations, around 800 to 900 kilometers above the equator. They follow a new path on every orbit. Geostationary satellites are more useful to operational meteorologists, as polar satellites do not view the same region continuously.
There are various types of satellite images, notes the CIMSS. The most useful ones are the visible, infrared and water vapor images, as these can be taken with a single satellite in the outer space.Learn more about Maps & Cartography
Current satellite images are available from a number of sources, including the United States Geological Survey and National Oceanic and Atmospheric Administration. Both organizations maintain regular access to observational and weather satellite technology.Full Answer >
It is possible to find the satellite view of a person's home by going on Google Maps and clicking the "satellite" button once the home address has been typed in. In fact, Google Maps can also give a person access to a satellite view of their entire street, town and state.Full Answer >
A satellite view of an address can be found on many websites, including Google.com, SatelliteViews.net and Mapquest.com. Many websites that offer maps or directions include the option to view an address in satellite mode.Full Answer >
The accuracy and reliability of maps created from satellite imagery depends upon the orbital device producing the images. As an example, the Pleiades-1A satellite, which was launched in December 2011, is capable of an image-location reliability of about 10 feet, and the accuracy can be increased to about 3.25 feet when ground control points, or GCPs, are used in conjunction with the satellite sensor. The Pleiades-1A satellite covers more than 386,000 square miles each day, and is capable of capturing images covering areas up to about 620 square miles.Full Answer >
