Remote sensing as a research area focuses on the acquisition, processing, and interpretation of information about the Earth or other targets without direct contact, primarily using sensors mounted on satellites, aircraft, drones, or ground-based platforms. It encompasses the study of electromagnetic radiation interactions with atmosphere, land, water, and biosphere, including multispectral, hyperspectral, radar, and LiDAR techniques. Research addresses sensor design, radiometric and geometric calibration, atmospheric correction, image fusion, and advanced retrieval algorithms for biophysical and geophysical variables. Applications span environmental monitoring, land-use and land-cover mapping, climate and cryosphere studies, hazard assessment, and support for geospatial modeling and data assimilation.
In February, NASA's ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is ...
