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.
A multi-institutional team of physicists and engineers has developed a laser-based radiation detection system that operates from as far away as 10 meters and perhaps farther. Their research is published in the journal Physical ...
On Wednesday 26 February, a thermal imaging camera built by researchers at the University of Oxford's Department of Physics will blast off to the moon as part of NASA's Lunar Trailblazer mission. This aims to map sources ...
