This is a process involving the transmission of radio waves of different frequency through different zones of the atmosphere, some of whom are absorbents of the radiation with the presence of atmospheric gases such as water vapor, carbon dioxide and ozone (Remote sensing, n.d.). Therefore the areas of electromagnetic spectrum where these gases are present are known as absorption bands. Absorption bands are represented by a low transmission value associated with specific ranges of wavelengths. On the other hand, the electromagnetic spectrum of the atmosphere with little or no absorption of the radiation due to the absence of atmospheric gases is called atmospheric windows. They are transparent to radiation and allow the transmission of specific wavelengths to the earth’s surface. The instrumentation of new devices is of great effect with the aviation and weather forecasting as they collect data from the reflections of sunlight from a line-of-sight with an object as well as record the frequency modulations on the basis of presence of carbon dioxide and other gases. ...
The essential purpose of this classification is meant for the optimum use of all the brightness levels available in the data. The photo integrated wavelength data are classified into two categories; supervised classification and unsupervised classification. The former is used for extracting quantitative information from remotely sensed photo data in order to separately allocate the available data into different known pixels to produce agent parameters for separate classes of interest. Most scientists use the MLC (maximum likelihood classification) classification with advantage of the mean vectors and multivariate spreads of each class. The effectiveness of supervised classification under MLC depends largely on the reasonable levels of accurate estimation of the mean vector m and the covariance matrix for arriving at each spectral data. The problem posed by this classification tool is that the accuracy of the estimation depletes when the classes are of a multimodal distribution (Liu, n.d.). The other classification model is the unsupervised classification. The basic feature of this classification is its independence to human interface by using some clustering algorithm to classify the image data. This classification model is essential for the identification of the number and location of the unimodal spectral classes on the basis of the image data. MMC or migrated means clustering classifier is the tools used in this model for labeling each pixel to unknown cluster centers with intend to move the pixel form one cluster center to another for accurate analysis of the image (ibid). 3. The radiation used for image analysis of the remote sensing function falls subject to the interaction between electromagnetic radiation and the ...Download file to see next pagesRead More

... A Journey to the Edge of the Universe Even if one has gone as far as a billion kilometers fromthe Earth into the outer space at the aim of having a concrete grasp of the universe, at least to beyond the Milky Way galaxy, it would take roughly another 20,000 kilometers to unravel what lies after the outskirts of the solar system from a point where visual contact with the human planet is lost. According to the collective findings featured in the National Geographic with the ultimate aid of the space probe, the journey begins at reaching 400,000 kilometers from home or approximately three days in spacecraft to land upon that spherical region which appears like a deserted battlefield. The moon, bombarded by millions of meteorites... the...

...Food chain is a representation of the energy transfers from one organism to another. It starts from a producer, usually plants, which are autotrophs that can harness light energy to form organic compounds. Plants are then used by primary consumers, or calves, for energy. These herbivores are then consumed by carnivores, such as humans. Upon death, these carnivores are decomposed by microorganisms into simpler compounds that can be utilized by the producers by nourishment. Geographers look at organisms in terms of how they are distributed on Earth. Usually, their association with other animals, such as that depicted in a food chain, gives an impression as to the place or habitat a particular food chain is present. As to...

...methods, that eruptions can be predicted in the future of Mount Rainier. Ingebritsen also documented the installation of new sensors in streams all over the mountain surface, which would constantly monitor temperature, electrical conductivity, and water pressure at hourly intervals, with the hope that in five to seven years data would provide conclusive evidence as to what, exactly, was going on beneath the surface. Volcanoes are an important part of the geologic and scientific history of the Earth. Their existence has had the power to thrill and awe, as well as devastate and humble mankind, for centuries. By advancing the science of prediction for their eruptions, it could be possible in the future to...

...by the Earth’s bovine population have an even greater impact upon overall CO2 levels than all human activity within any given year. However, this should not be seen to delegitimize the processes whereby humans can provide additional negative impacts upon the global environment. Due to the fact that the Earth is ultimately a closed system, it can only integrate a certain amount of change before negative impacts are seen. As such the Earth’s ecological system might be able to integrate with volcanic eruptions or the methane gas produced by cows; however, further integration of the ever-increasing levels of human CO2 emissions is likely well beyond the capabilities of the system as a whole....

...Question # 1 The four individuals attributed to the development of modern astronomy after the initial developments by Copernicus are Galileo Galilei (1564- 1642), Johannes Kepler (1571-1630) Isaac Newton (1642 – 1727), and Albert Einstein (1879 to 1955). Galileo’s discoveries were on the fields of both physics and astronomy, he is considered to be the founding father of modern science. He was the first to invest and use the telescope. Through the telescope he discovered the phases of Venus and the moons of Jupiter. Kepler through kepler’s laws, paved the way for developing the field of celestial mechanics. He specifically described the planet’s revolution around the sun. Newton contributed to astronomy and physics by coming... up with the...

...In this article, an earthquake off of the coast of central Chile frightened thousands of people. The citizens of this nation were frightened for several reasons. The magnitude 6.2 earthquake was centered about 31 miles off of the Chilean coast. It was powerful enough to make people’s homes sway, knocking things off of shelves and causing light fixtures to dance about. Panic sent many people fleeing from their homes. Cell phone service broke down because the system was not able to handle all of the calls from people calling loved ones to let them know they were unharmed. Social media sites also were buzzing with news of the earthquake. Another reason people in central Chile were so upset is the fact that this same area... this article,...

...Earth Science This success story belongs to the time when the Empire Building in New York went green, one window after the other. It was amonumental task especially because it involved replacing each of the 6,514 windows which amounted to more than 26,000 panes of glass. The going green debated basically meant that the Empire State Building was ready for an overhaul. Since this is a very old structure, nothing of this stature has ever taken place. It has made people realize that almost anything is possible if the willpower is there. From an environmental perspective, it gives the commoners food for thought that if they apply themselves whole-heartedly towards the cause of the environment, there would be...
