Remote Sensing for environmental resource mapping

Remote sensing is the science and art of collecting, obtaining, analyzing, information of an impartial sensations or area acquired by a device that is not in contact with the purpose, zone or portents under research. Remote sensing is the outcome of development of science and technology. Although, it has wide range of application for environmental source investigation, supervision, demonstration and mapping. It is increasingly been used because of its different positive aspects such as repetitive use in all seasons with high accuracy in different context.

Remote sensing is the mechanisms, systems and devices to observe the earth's surface at a distance and to interpret the images obtain in order to acquire meaningful information of a particular substances on earth. The characteristics measured by a sensor are the electromagnetic energy reflected on emitted by the ground apparent. A true colorful is made sensitive to the primary colors by coating three separate color layers – blue, green, red. It is also cost effective inaccessible parts or areas such as, high altitude mountain at the time.
