Fundamental Concepts Of Aerial Photography, Remote Sensing, GPS & Geographical Information System (GIS)

Remote sensing encompasses the practice of aerial photography. Aircraft and satellites are the most popular and pervasive platforms used for remote sensing observations. Topographical mapping, environmental research, engineering, mineral and oil exploration, and many more fields find use for aerial photography, which is a subset of remote sensing. Aerial photography relied on balloons & kites in the beginning, but with the creation of airplanes in 1903, they have become the standard method. Air and space-borne photography serves the purpose of capturing diverse views of Earth, allowing observers to witness the planet's flora, resources, and landscapes. These images, obtained through various methods such as remote sensing and aerial photography, depict landscapes from above. A systematic overlapping flying pattern at a specific height is employed in aerial photography, utilizing satellites, balloons, helicopters, or aircraft to generate photographic pictures. The primary objective of this approach is map creation. The field of study known as "remote sensing" focuses on the acquisition, analysis, and presentation of geographical data obtained from a considerable distance. This involves aerial footage and still images captured through the electromagnetic spectrum.
