Welcome to Basics of Remote Sensing on STARKFX.com!
Remote sensing, as treated here, is all about "looking" at the earth's surface -or some other surface- from a long distance and "seeing" important features and details. Systems recently launched from my neighborhood now give commercial images of earth with resolution on the order of half a meter. I have worked on multispecteral and hyperspectral systems giving 10nm wavelength resolution, radiometric systems with a fraction of a degree temperature resolution and some earth based systems detecting radiation in only sharply defined bands. The pages linked to this one serve as my notes on the basics of such systems.
