ABSTRACT
There are many sources of remote sensing data. The primary sources are ground-based, aircraft, or satellite optical scanners. The data may be acquired digitally as with a multispectral scanner (MSS) or a coastal zone scanner (CZS), for example, or from digitized photographic imagery as taken with Hasselblad cameras from the Space Shuttle. A technique that is currently being applied is optical remote sensing with three-or fourcolor digital cameras with focal plane arrays. The pixel range of quantification is generally 16 bits but may be less.
