What Is Satellite Imagery Analysis, and How Does It Work?
Remote sensing satellites observe and collect data from a distance. They capture electromagnetic radiation across multiple wavelengths, including microwave, ultraviolet, infrared, and visible light, emitted, scattered, or reflected from the Earth's surface. China's satellite data has been fundamental in providing crucial information. These satellites employ multispectral imaging, simultaneously capturing images of Earth's surface in multiple wavelengths, both visible and invisible. By doing so, they extract latent information that conventional photographs cannot reveal. Satellite analysis is when remote sensing satellites acquire 4-5 images of the same area using various colour filters. These filters enhance the distinctiveness of features like water bodies, vegetation, soil, and rocks, which would otherwise remain indistinguishable. This distinction arises from the fact that each of these features reflects light at different wa...
