Table Of Contents. 1.3 The Electromagnetic … The parameters that characterize a wave motion are wavelength (λ), frequency (ν) and velocity (c) (Fig. Nicolas, F. Parol and L. Labonnote, Laboratoire d'Optique Atmosph. 3.3.2.2 Electromagnetic Radiation. The reflected radiance is also attenuated after passing through the atmosphere. Yeung Definition Theacquisition of information about an object without physical contact. Sensors detect and measure electromagnetic energy in different portions of the spectrum. Source of Remote Sensing data is the Electromagnetic radiation reflected or emitted from an object. Electromagnetic waves are energy transported through space in the form of periodic disturbances of electric and magnetic fields.

However, in remote sensing the most useful regions are the visible (0.4-0.7 µm), the reflected IR (0.7-3 µm), the thermal IR (3-5 & 8-14 µm) and the microwave region varies from 0.3-300 cm. - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. Download as PDF. Airborne platforms ; Aircraft ; Balloons ; Spaceborne platforms ; Satellites ; The Space Shuttle Remote Sensing definition 1. science and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a device that is not in physical contact with the object, area or phenomenon under investigation. Set alert. The fundamental unit of electromagnetic phenomena is the photon, the smallest possible amount of electromagnetic energy of a particular wavelength. The elements of Data Acquisition are (a) Energy source, (b) Propagation of energy through the atmosphere, (c) Energy interactions with earth surface features, (d) Airborne and/ or spaceborne sensors, (e) Generation of sensor data. The electromagnetic ... Multisensors remote sensing of cloud properties from POLDER2/Adeos2 and MODIS/Terra J. Riedi, C. Oudard, JM. electromagnetic radiation (EMR) from the Earth‘s surface. All electromagnetic waves travel through space at the same speed, c = 2.99792458 x 10 8 m/s, commonly known as the speed of light. remote sesing is the art, science and tecnology to obtain reliable information of an object on the surface of the earth without comming into physical contact. • Light travels through the vacuum of space – unlike sound. In remote sensing applications, the electromagnetic energy is normally classified according to its location in the electromagnetic spectrum, that is, by its wavelength (Figure 2). Fig. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. Remote Sensing: using electromagnetic spectrum to image Platforms for remote sensing ... Electromagnetic radiation is energy consisting of an electrical (E) and magnetic (M) fields oriented at right angles of each other that travels through atmosphere at the speed of light … Remote sensing is the science and art of identifying, observing, and measuring an object without coming into direct contact with it. in Remote sensing. Homework Content. All these technologies are integrated to act as one complete system in itself, known as Remote Sensing System. The infrared region can be divided into two categories based on their radiation properties - the reflected IR, and the emitted or thermal IR.
