Impact of Remote sensing and GIS in Environmental Sciences

Remote sensing

[su_highlight background=”#2dca95″ color=”#ffffff”]Remote sensing and Geographic information system (GIS) plays a key necessary role in environmental mapping, mineral exploration, agriculture, forestry, geology, water, ocean, infrastructure coming up with, and management, etc. Remote Sensing and GIS have mature as a serious instrument for assembling info on nearly every side of the world for the previous couple of decades. Remote sensing provides the immense scope of exploring, analyzing, distinctive, and monetization of undeveloped regions.[/su_highlight]

What is Remote Sensing?

Remote sensing is just outlined because of the scanning of the world by satellite or high-flying craft so as to get info regarding it.

Remote sensing technique has emerged as a good methodology for consistently measuring, analyzing, and higher management of natural resources E-g (land, soil, water, forests, mountains) similarly because of the watching of the geological process, flood, drought, and landform amendment. Remote sensing provides the immense scope of exploring, analyzing, distinctive, and monetization of undeveloped regions. Remote sensing is outlined per bound function. It includes gaining knowledge of an object’s property by a tool. the knowledge includes measurements of force fields, nonparticulate radiation, or acoustic energy for craft, spacecraft, or ships. The devices have a camera, lasers, frequency receivers, measuring instrument systems, sonars, seismographs, gravimeters, magnetometers, and scintillation counters.

Overview of Remote Sensing in Environmental Sciences:

Remote sensing has been recognized as a valuable tool for viewing, analyzing, characterizing, and making decisions about our environment.

Following are some applications for remote sensing in different fields.


Agriculture plays a key role within the economies of developed, undeveloped, and developing countries. Remote sensing has found to be the most beneficial tool for observation, analysis, and management of water and crop resources. Agricultural applications of remote sensing embody crop sort classification, crop condition assessment, crop yield estimation, mapping of soil characteristics, mapping of soil management practices, and compliance observation.

Land Cover:

Land cover is one of the foremost typical and vital remote sensing knowledge. Land refers to the healthy ground surface E-g Forest, grassland, concrete, etc.

Forests are a valuable resource for providing food, huts, life nest, fuel, and lots of different dailies provides like meditative ingredients and paper. Forests play a very important role in equalization the earth’s greenhouse emissions (Carbon dioxide).

Remote sensing permits for economical management of forest resources. These resources embody wood, forage, water, wildlife, recreation, timber management, maintenance, and improvement of existing forest stands and preparation. Satellite and remote sensing pictures, with air ikon interpretation, combined with forest classification maps, facilitate to see the quantity of timber harvested from a personal tree or stand of trees.


Geology involves the study of landforms, structures. it’s most ordinarily understood because the exploration and exploitation of mineral/hydrocarbon resources boost the quality of living in society.

Geological applications of remote sensing embody the following: Base mapping, lithological (The study of Rocks) mapping, structural mapping, sand and gravel exploration/exploitation, mineral exploration, organic compound exploration, environmental earth science, baseline infrastructure, event/monitoring, geo-hazard mapping, and planetary mapping.

What is Geographic Information System (GIS)?

GIS is a computer-based tool that analyzes, stores, manipulates, manages, and visualizes geographic data, sometimes in a very map. The keyword in this technology is Geography. GIS will be used as a tool in each issue’s resolution and decision-making processes, likewise as for the visual image of knowledge in a very spatial atmosphere. everybody is aware that maps build geographic data easier to know.

GIS really comes down to just 4 simple ideas:

  • Create geographic data
  • Manage
  • Analyze
  • Display it on a map.

Overview of GIS in Environmental Sciences:

Mapping the Things:

Mapping wherever the items are, we are able to map the abstraction location of real-world options and visualize them.

Mapping Quantities:

People map quantities, like wherever the foremost and least is, to search out places that meet their criteria or to envision the relationships between places.

Mapping densities:

Sometimes it’s additionally necessary to map concentrations or an amount normalized by space or total range.

Finding what is inside:

We can use GIS to work out what’s happening or what options are situated in a specific area/region. we are able to verify the characteristics of “inside” by making specific criteria to outline a part of interest (AOI).

Finding what is nearby:

We can establish what’s happening inside a collection distance of a feature or event by mapping what’s near exploitation geoprocessing tools like BUFFER.

Newly advanced methodologies that are a Geographic system (GIS) and Remote Sensing (RS) vital tools to work out and facilitate to resolve delineated issues to observe the surroundings for risk assessment and management square measure required to fulfill new challenges together with terrorist attacks. Some come exploitation remote sensing strategies with satellite knowledge and GIS computer code that are subjected to observe water quality and concrete chancing up to the time at the portable basin and dam are shown, giving examples on however this integration of multisource data works currently and advise the new technologies within the close to future.
