Remotely sensed data refers to information collected from a distance, typically using satellites or aircraft equipped with sensors. This data can include images, measurements, and other forms of information about the Earth's surface and atmosphere. Remote sensing technology allows researchers to gather data on a wide range of environmental factors, such as land cover, vegetation health, temperature, and air quality. This type of data is often used for monitoring and studying changes in the environment, natural disasters, urban development, and agricultural productivity. Remote sensing data is valuable for various fields including environmental science, geography, agriculture, and urban planning.
