WebReflective is an adjective that can describe a person who thinks things through, or a surface that reflects light or sound, like the reflective lettering on a stop sign. WebNov 1, 2016 · Optically thick clouds preclude remote sensing of the surface at reflective wavelengths and so cloud mask results were stored for each 30 m pixel. It is well established that cloud masking is complex.
WebAug 23, 2013 · Reflectance is the proportion of the radiation striking a surface to the radiation reflected off of it. Some materials can be identified by their reflectance spectra, so it is common to correct an image to reflectance as a first step toward locating or identifying features in an image. Top of Atmosphere Reflectance WebRemote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from …
WebReflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared imagery. There has been no aesthetic use of UV imaging to drive technology development as there have been in the near-IR band. Remote sensing data acquired from instruments aboard satellites require processing before the data are usable by most researchers and applied science users.
