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
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
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
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
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
A brief history of Remote Sensing The beginning of remote sensing starts from capturing aerial photography with the help of balloons, kites, pigeons, and gliders. In late 1908 after the development of operational aircraft, the first functional aircraft was used for aerial photography. During World War I and II the aerial photographs were used as … Read more
At present, one of the most powerful instruments for the study of climate change ecology, land use land cover changes, ocean temperature, and salinity, and forest application is satellite remote sensing, which measures the flow of radiation entering and exiting the upper atmosphere. After 1962, the term “remote sensing” became popularized, and it typically refers … Read more
General Introduction: What is Urban Heat Island ? The concept of urban heat island is defined as a zone of warmer temperatures in the center of a city produced by enhanced absorption of solar radiation by urban surfaces and by waste heat release. We call the central area an urban heat island because it has … Read more
Introduction: After the development of remote sensing technology, the study of the earth’s natural resources become easy. The term remote sensing stands for observing something from the distance. The sensing of some things can be done by using a remote sensor that is mounted on a suitable platform such as a ground-based, air-based, and satellite-based … Read more
Remote Sensing is derived from two words, REMOTE + SENSING Remote means distance Sensing means observation Remote sensing means ‘sensing an object or phenomenon, from a distance with the help of a suitable device/platform. “Colwell (1984)” Remote sensing is the acquiring of data about an object without touching it. “American Society of Photogrammetry, 1952; 1966” … Read more
