INTRODUCTION TO HYPERSPECTRAL REMOTE SENSING

Remote Sensing and Digital Image Processing (DIP) / /
Content

Introduction Remote sensing involves the examination of features observed in several regions of the electromagnetic spectrum. Conventional remote sensing, as outlined in previous chapters, is based upon the use of several rather broadly defined spectral regions. Hyperspectral remote sensing is based upon the examination of many narrowly defined spectral channels. HYPERSPECTRAL REMOTE SENSING Hyperspectral remote […]

Electromagnetic Radiation (EMR) and Electromagnetic spectrum

Remote Sensing and Digital Image Processing (DIP) / /
Content

ELECTROMAGNETIC RADIATION Definition: Electromagnetic radiation (EMR) is a form of “energy”, that consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. Electromagnetic radiation (EMR) is a form of energy that is produced by oscillating electric and magnetic disturbance, or by the movement of electrically charged particles traveling through a

WHAT IS THE HYDROLOGICAL CYCLE MAJOR PROCESS OF HYDROLOGICAL CYCLE EVAPORATION Factors Affecting Evaporation (Evaporation is inversely proportional to salinity, at the same temperature oceanic water evaporates approx. 5% less than fresh water.) (Evaporation accounts for 90 percent of the moisture in the Earth’s atmosphere; the other 10 percent is due to plant transpiration. )

The Greeks were pioneers in many branches of knowledge their period is known as the Golden Age of Greece. The ancient period of geography was an exploration, and mapping of the areas and the collected material. Geographical knowledge had been a concomitant of a different civilization. Greeks borrowed many concepts of Astronomy, Geometry, and mathematics
