AICTE approves inclusion of Geospatial as a subject in GATE and NET exam

Posted On: 23 SEP 2020 2:07PM by PIB Delhi

Students competing for the popular National Eligibility Test (NET) for Junior Research Fellowship (JRF) and lectureship in Indian universities and colleges, including IITs and NITs and Graduate Aptitude Test in Engineering (GATE) for JRF in CSIR laboratories, can now opt for Geospatial as a subject.

The All India Council of Technical Education (AICTE) has approved for the inclusion of Geospatial subject in GATE and NET examination on the recommendation of the National Geospatial Task Force Report 2013 under the Chairmanship of former ISRO Chairman, Dr. K. Kasturirangan.

Department of Science and Technology (DST) as an organisation and many professionals have highlighted the need for Geospatial subject especially in GATE and NET examination at different forums.

Dr. K. C. Tiwari (Retd. Col), Department of Science and Technology's Geospatial Chair Professor, Centre of Geoinformatics, Delhi Technological University, had made sincere efforts for inclusion of Geospatial Subject in the GATE and NET examination, and the decision was an outcome of DST's insistence and his hard work.

This will benefit the increasing number of students who are taking up geospatial as a subject at different levels and help in the evolution of Geospatial Ecosystem in the country

The Natural Resources Data Management System (NRDMS) under DST is an interdisciplinary research programme which promoted R&D in emerging areas of geospatial science, technology, and its applications to area-specific problems. Over the years, it has successfully demonstrated utilities of geospatial technologies in decision making and developed capacity for geospatial data and information management at state, district, and local levels at pilot scale.

Now, it is evolving into National Geospatial Programmeforcatalyzing the national geospatial ecosystem and promoting geospatial science and technology solutions, capacity building, entrepreneurship, and international cooperation for sustainable sociology-economic development at all levels of governance and also stressing on including geospatial subject at different levels.

"Geospatial science and technology is a rapidly evolving subject that forms the backbone of a plethora of planning, development and governance activities with unprecedented opportunities both in the government and private sectors. Swamitva, a recent scheme launched by the Prime Minister is a good example to map rural inhabited lands using drones and latest survey methods. The scheme among other things will streamline planning, revenue collection and property rights and thus have a huge positive impact on securing loans by the owners and dispute resolution related to properties," said Prof Ashutosh Sharma, Secretary, DST.

REMOTE SENSING INDICES

Remote sensing indices are band ratios designed to highlight specific surface features (vegetation, soil, water, urban areas, snow, burned areas, etc.) using the spectral reflectance properties of the Earth's surface. They improve classification accuracy and environmental monitoring. 1. Vegetation Indices NDVI – Normalized Difference Vegetation Index Formula: (NIR – RED) / (NIR + RED) Concept: Vegetation reflects strongly in NIR and absorbs in RED due to chlorophyll. Measures: Vegetation greenness & health Uses: Agriculture, drought monitoring, biomass estimation EVI – Enhanced Vegetation Index Formula: G × (NIR – RED) / (NIR + C1×RED – C2×BLUE + L) Concept: Corrects for soil and atmospheric noise. Measures: Vegetation vigor in dense canopies Uses: Tropical rainforest mapping, high biomass regions GNDVI – Green Normalized Difference Vegetation Index Formula: (NIR – GREEN) / (NIR + GREEN) Concept: Uses Green instead of Red ...

Atmospheric Window

The atmospheric window in remote sensing refers to specific wavelength ranges within the electromagnetic spectrum that can pass through the Earth's atmosphere relatively unimpeded. These windows are crucial for remote sensing applications because they allow us to observe the Earth's surface and atmosphere without significant interference from the atmosphere's constituents. Key facts and concepts about atmospheric windows: Visible and Near-Infrared (VNIR) window: This window encompasses wavelengths from approximately 0. 4 to 1. 0 micrometers. It is ideal for observing vegetation, water bodies, and land cover types. Shortwave Infrared (SWIR) window: This window covers wavelengths from approximately 1. 0 to 3. 0 micrometers. It is particularly useful for detecting minerals, water content, and vegetation health. Mid-Infrared (MIR) window: This window spans wavelengths from approximately 3. 0 to 8. 0 micrometers. It is valuable for identifying various materials, incl...

Energy Interaction with Atmosphere and Earth Surface

In Remote Sensing , satellites record electromagnetic radiation (EMR) that is reflected or emitted from the Earth. Before reaching the sensor, radiation interacts with: The Atmosphere The Earth's Surface These interactions control how satellite images look and how we interpret them. I. Interaction of EMR with the Atmosphere When solar radiation travels from the Sun to the Earth, four main processes occur: 1. Absorption Definition: Absorption occurs when atmospheric gases absorb radiation at specific wavelengths and convert it into heat. Main absorbing gases: Ozone (O₃) → absorbs Ultraviolet (UV) Carbon dioxide (CO₂) → absorbs Thermal Infrared Water vapour (H₂O) → absorbs Infrared Concept: Atmospheric Windows These are wavelength regions where absorption is very low, allowing radiation to pass through the atmosphere. Remote sensing depends on these windows. For example, satellites like Landsat 8 use visible, near-infrared, and thermal bands located in atmospheric windows. 2. Trans...

Landsat band composition

Short-Wave Infrared (7, 6 4) The short-wave infrared band combination uses SWIR-2 (7), SWIR-1 (6), and red (4). This composite displays vegetation in shades of green. While darker shades of green indicate denser vegetation, sparse vegetation has lighter shades. Urban areas are blue and soils have various shades of brown. Agriculture (6, 5, 2) This band combination uses SWIR-1 (6), near-infrared (5), and blue (2). It's commonly used for crop monitoring because of the use of short-wave and near-infrared. Healthy vegetation appears dark green. But bare earth has a magenta hue. Geology (7, 6, 2) The geology band combination uses SWIR-2 (7), SWIR-1 (6), and blue (2). This band combination is particularly useful for identifying geological formations, lithology features, and faults. Bathymetric (4, 3, 1) The bathymetric band combination (4,3,1) uses the red (4), green (3), and coastal bands to peak into water. The coastal band is useful in coastal, bathymetric, and aerosol studies because...
