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

Biodivetsity

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

55 Global Position System: Different Segments of GPS, its working Principle, Popular Substitute of GPS

GPS (Global Position System)

Introduction Global positioning system (GPS) is also known as Navigation System with Time And Ranging Global Positioning System (NAVSTAR) GPS. It is a GNSS (global satellite-based navigation system) system that covers the entire earth. GPS system was originally developed for military purposes, but after some time it is being used by civilians for various purposes … Read more

54 Geometric Corrections in Remote Sensed Image

Geometric Corrections

Introduction Remote sensing is the science of collecting information about any object on a surface from a well-defined distance with a proper sensor. In general, it may define as a technique of gathering data of the surface of the earth from a distance with a sensor mounted on a moving platform. Remote sensing can be … Read more
