65 Impact of Global Climate Change on Marine Ecosystem

Marine Ecosystem

Introduction: Marine Ecosystem The oceans encompass over 70% of the Earth’s surface, emphasizing their importance to the global environment. In addition to having a huge effect on global heat transfer and precipitation, the seas are home to a diverse range of marine creatures. 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

60 What is Climate Change and its Dangerous Effects on Earth

Climate Change

What is Climate Change? Before starting the concept of climate change first we need to understand the term climate “It is the long-term average of weather incidents in a certain region. The climate of the Earth (Structure & Composition of the Atmosphere) is not constant. It has altered several times over billions of years due … 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

58 What is Biodiversity? Major Cause of Biodiversity Loss and Conversation Methods


Introduction: Biodiversity The biodiversity present on Earth today is made up of many millions of diverse biological species that have evolved over four billion years. Biodiversity refers to the diversity of life on Earth, which encompasses all creatures, species, and populations, as well as genetic variation among them and their complex assemblages of communities and … Read more

57 LIDAR Remote Sensing: Historic Development, components, and Advantage of LIDAR Remote Sensing

Lidar Remote Sensing

Introduction: LIDAR Remote Sensing Lidar remote sensing is the modernist form of remote sensing (The Basic Concept of Remote Sensing). It stands for “light detection and ranging,” which is similar to radar (The Concept of Microwave Remote Sensing, its Geometry, and its Applications) imaging in that both families of sensors are intended to broadcast energy … Read more
