IIRS Outreach Programme on
Remote Sensing and Digital Image Analysis
20th August - 14th September 2018
Outreach Programme on Remote Sensing and Digital Image Analysis was organized by Indian Institute of Remote Sensing (IIRS) Derhadun at Dronacharya Group of Institutions,Greater Noida through A-View during 20th Aug. 2018 - 14th Sept. 2018.
The program started on 20th August 2018, with the inaugural address by Dr. A. Prakash Chauhan, Director IIRS. Thereafter, he conducted the introductory session covering Space Based Observation for Earth System Studies through Indian Space Programme, Earth System Studies and Space, LEO and GEO Research Platforms, Evaluation of EO Sensors in India and Indian Earth Observation Satellite. During the session, Dr. Chauhan also discussed major earth observation applications, i.e., flood and water security, infrastructure development, social empowerment, environment and ecosystem, disaster management, ocean and marine resources, weather and climate.
Scientists and Researchers conducted several sessions during the Outreach Program.
Mrs. Manu Mehta, Scientist from Photogrammetry and Remote Sensing Department discussed Basics of Remote Sensing. She focused on wave particle duality, visible range, infrared range, microwave range, radiometry, blackbody, Plank’s law of radiation, spectral emissivity, EMR interaction with matter and earth surface, and interaction process by reflection, transmission and absorption.
Mr. Vinay Kumar, Scientist - PRSD (Photogrammetry and Remote Sensing Department) conducted the session on Earth Observation Sensors and Platforms. He explained the history of RS from 1827 to 1972.
Mr. Yogesh Kant, Scientist from Marine & Atmospheric Science Department conducted the session on Thermal Remote Sensing. He discussed the heat capacity, thermal conductivity, thermal inertia, thermal diffusivity, uses of spectral band, applications of TIR remote sensing, history of thermal infrared remote sensing and thermal infrared data collection.
Dr. Hina Pande from Photogrammetry & Remote Sensing Department discussed Spectral Signatures and Image Interpretation. The elements of image interception were also highlighted.
Ms. Minakshi Kumar from Photogrammetry and Remote Sensing Department, discussed “Digital Image Processing - Basic Concepts”. She gave a brief description of earth’s rotation effect- image offset (skew), rectification, image to map rectification procedure, ground control points. Polynomial coordinates transformation, mathematical transformation, root mean square error, acceptable RMS error, intensity interpolation were also briefed.
Dr. Poonam S. Tiwari, Scientist, discussed “Digital Image Enhancement Techniques”. She also explained histogram equalization, spatial frequencies, spatial filtering, filtering, and types of filter, Robert’s edge detector, Kirsch edge detector, image transformation and image division.
Mr. Shashi Kumar, Scientist, discussed “Microwave (SAR) Remote Sensing”. He discussed the nine SAR satellites, i.e., RISAT-1, RADARSAT-1, RADARSAT2, ERS1 etc., radar geometry, synthetic aperture radar, ground swath width, SAR resolution, azimuth resolution, range resolution, slant range/ground range, SAR data, radar polarization, SAR modes, geometric distortions in radar, layover, shadow, surface roughness, radar polarization, smooth and rough “Rayleigh Criteria”, radar backscatter and incidence angle, incidence angle and local incidence angle, volume scattering, Complex SAR Image and speckle.
Mrs. Shefali Agrawal from Photogrammetry and Remote Sensing Department, discussed “Hyper Spectral Remote Sensing”. She also explained different kinds of image, i.e., true-color and false-color image, land sat and bands, hyper spectral remote sensing, spectral sensing.
