CE2024 REMOTE SENSING TECHNIQUES AND GIS
OBJECTIVE
To introduce the students to the basic
concepts and principles of various components of
remote sensing.
To provide an exposure to GIS and its
practical applications in civil engineering.
UNIT I EMR AND ITS INTERACTION WITH ATMOSPHERE & EARTH
MATERIAL
Definition of remote
sensing and its components -
Electromagnetic spectrum - wavelength
regions important to
remote sensing - Wave
theory, Particle theory,
Stefan-Boltzman and
Wein’s Displacement
Law - Atmospheric
scattering, absorption -
Atmospheric windows -
spectral signature concepts - typical spectral reflective characteristics of
water, vegetation and
soil.
UNIT II PLATFORMS AND SENSORS
Types of platforms - orbit types,
Sun-synchronous and Geosynchronous - Passive and Active
sensors - resolution
concept - Pay load
description of important
Earth Resources and
Meteorological
satellites - Airborne and spaceborne TIR and microwave sensors.
UNIT III IMAGE INTERPRETATION AND ANALYSIS
