Humans largely impact climate through emissions from fossil fuels, industrial, agricultural, and … Read more

64 What is Geographic Information System (GIS): The concept of GIS, why do we need the GIS and its components?

Geographic Information System

Introduction Most of the time, we use our geographic knowledge for everyday activities like figuring out a route in a new location or looking for the nearest diner. Spatial information has a more significant influence on our lives than we know since it helps us generate the food we eat, the energy we use, the … Read more

63 Unmanned Aerial Vehicle(UAV): Futuristic Technology of Remote Sensing


Introduction:- Drones are revolutionizing remote sensing and GIS applications. For example, a Drone can be used by a farmer to collect photographs of complete fields to gather insights into the state of his crop. The significant advantage of the UAV machines is that this can be done more quickly, easily, and cheaply compared to conventional … Read more

62 What is Desertification? Major Impact, Objective of WDCDD 2022, and what causes of a Drought and How Can We Quantify It?

World Day to Combat Desertification and Drought Quiz

What is Desertification? Desertification refers to the deterioration of land in arid, semi-arid, and dry sub-humid environments. It is mostly caused by human activity and climate variables. Desertification is not synonymous with the growth of existing deserts. Dryland ecosystems occupy more than one-third of the world’s land area and are especially vulnerable to overexploitation and … Read more

59 What is Hyperspectral Remote Sensing and its important Applications

Hyperspectral Remote Sensing Image

Introduction: Hyperspectral Remote Sensing Researchers and scientists utilize hyperspectral remote sensing, (also known as imaging spectroscopy), to identify terrestrial vegetation, minerals, and land use/land cover mapping. Remote sensing involves the examination of features observed in several regions of the electromagnetic spectrum (Remote Sensing Using the Thermal Infrared Spectrum Range). Hyperspectral remote sensing will boost remote … Read more
