Introduction To Remote Sensing Pdf Pdf Image Resolution Lidar In optical remote sensing, sensors detect solar radiation in the visible, near , middle and thermal infrared wavelength regions, reflected scattered or emitted from the earth (table 1). Remote sensing is the science (and to some extent, art) of acquiring information about the earth's surface without actually being in contact with it. this is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Applications of thermal infrared remote sensing can be broadly classified into two categories one in which surface temperature is governed by man made sources of heat and other in which it is governed by solar radiation. Remote sensing (rs), also called earth observation, refers to obtaining information about objects or areas at the earth’s surface by using electromagnetic radiation (light) without being in direct contact with the object or area. so, remote sensing is day to day business for people.

The document outlines the stages of remote sensing data acquisition from the energy source to data products. it also explains the basic principles including electromagnetic energy, its interaction with the atmosphere and earth's surface, and the spectral signatures measured by sensors to detect landscape features from different platforms. Hyperspectral remote sensing will advance remote sensing’s analytical powers to new levels and will form the basis for a more thorough understanding of how to best develop future remote sensing capabilities. This paper starts with a brief historic overview of remote sensing and then explains the various stages and the basic principles of remotely sensed data collection mechanism.
