CE2024 REMOTE SENSING TECHNIQUES AND GIS

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                                                     

Types of Data Products - types of image interpretation - basic elements of image interpretation - visual interpretation keys - Digital Image Processing - Pre-processing - image enhancement techniques - multispectral image classification - Supervised and unsupervised.

UNIT IV           GEOGRAPHIC INFORMATION SYSTEM                                                           

Introduction - Maps - Definitions - Map projections - types of map projections - map analysis -
GIS definition - basic components of GIS - standard GIS softwares - Data type - Spatial and
non-spatial (attribute) data - measurement scales - Data Base Management Systems (DBMS).

Data models  - vector and raster data  - data compression  - data input by digitization and scanning  -  attribute  data  analysis  -  integrated  data  analysis  -  Modeling  in  GIS  Highway alignment studies - Land Information System.
