remote sensing systems

. For this, we require a data-gathering system to map and monitor the urban sprawl. Remote sensing offers excellent possibilities in solving this problem. (11) A specialized application of remote sensing is in the field of defense, both for gatherin..

"Remote Sensing" can be defined as obtaining information about an object by observing it from a distance and without coming to actual contact with it. Infact when we see an object and understand what it is, our eye is sensing that object remotely. This ..

Remote Sensing - The cameras used on Landsat satellites are extremely complex. They use a process called remote sensing, in which the cameras scan the earth to look for different patterns of radiation. The Landsat cameras view the earth both in visible light,..

Need of Measurement and System of Units - Before all the branches of science were clubbed together under the nomenclature 'Natural philosophy', under which all observations of subjective nature were being carried out and spirit of enquiry was almost non-existent, we were satisfied with si..

The nervous system carries out the following functions: It perceives the changes around us through our senses. It controls and coordinates all the activities of the muscles in response to the changes outside. It also maintains the internal environment of the body by coordinating..

India had abundant forest cover in ancient times. But increase in population, lack of foresight and indiscriminate felling of trees has greatly reduced the forest cover. Remote sensing surveys have shown that at present the forest cover is only 14..

The neurons that conduct impulses from the receptors or sense organs to the central nervous system are called the sensory neuron..

Receptors are structures at the ends of the nerve fibres that collect the information to be conducted by the nerves. These receptors may be specialised sense organs like the Meissner's corpuscles of the skin, specialised nerve endings like the Pacinian corpuscles of skin or the specialise..
