Unit 1
Introduction, Basic concepts and principles of remote sensing; Definition components of remote sensing – energy sensor, interacting body – active and passive remote sensing – platforms – EMR interaction with earth surface material, radiance, irradiance, incident, reflected, absorbed and transmitted energy – reflectance – specular and diffused reflection surfaces – spectral signature – spectral signature curves – EMR interaction with water, soil and earth surface. Application; Meteorology, land use, networking, hydrological studies, soil studies and coastal zone analysis.
