Term Definition/Description Source
Kalman filtering The recursive minimum variance estimation of an unbiased stochastic variable. An a priori estimate and covariance are linearly combined with new data to form an updated estimate and covariance. HDBK-850
Kelvin A thermometer scale starting at absolute zero (approximately -273 degrees Celsius ) and having degrees of the same magnitude as those of the Celsius thermometer. Thus 0 degrees C = 273 degrees K, also called the absolute scale. USIS 95
Kepler's laws The three laws governing the motions of planets in their orbits: (1) the orbits of the planets are ellipses, with the Sun at a common focus; (2) as a planet moves in its orbit, the line adjoining the planet and Sun sweeps over equal areas in equal intervals of times; (3) the squares of the periods of revolution of any two planets are proportional to the cubes of their mean distances from the Sun. Also called Kepler's planetary laws. HDBK-850

Key Area of Interest (KAI) Portions of installations that do not necessarily relate directly to any defined facility within that installation. A KAI is also used to identify any unique imagery collection and production requirements of a select portion of an installation. KAIs are designated by a 15 character BE number. USIS 95
key flat The principal or master layout or flat used as a positioning guide for stripping up other flats. Also called layout guide. See also flat, definition 1; layout. HDBK-850
keyword (UCDM Entity: "KEYWORD") A reference point for finding other words or information. USIGS/CDM-A
K-factor See base altitude ratio. HDBK-850
kiss plate A press plate used to make an addition or correction to a previously printed sheet. Also called touch plate. HDBK-850
Klimsch-Variomat compilation method (relief) A process by which reproduction material of large-scale sheets is photographically filtered to retain only index contours. The index contours are then used as the relief compilation for a medium-scale sheet. HDBK-850
knowledge base A collection of interrelated information, facts, or statements. [IEEE 610.5] IEEE 610-1990
knowledge base A data base of knowledge about a particular subject. The data base contains facts, inferences, and procedures needed for problem solution. Webster Computer
knowledge based system (KBS) An AI [automated information] application that uses a database of knowledge about a subject. See expert system. Freedman 1995
Kodak image editing workstation A softcopy work station primarily used to manipulate and annotate images. USIS 95
Korean Air Intelligence System The computer system used in the Republic of Korea (ROK) intelligence cell. USIS 95
Korean Analysis Center The intelligence cell manned by Republic of Korea (ROK) personnel. USIS 95
Korean Combat Operations Intelligence Center (KCOIC) The Korean and U.S. intelligence center at Osan Air Base, Korea. USIS 95
Korean Intelligence Support System Provides all-source intelligence support to United States Forces Korea (USFK) and Combined Forces Command (CFC). Capabilities include indications and warning, collection requirements management, exploitation and dissemination, Integrated Data Base (IDB) maintenance and data access, automated message handling, access to counterterrorist data base, map graphics analysis, analyst support tools and General Military Intelligence. It also supports access to national level data bases via Defense Secure Network-3. USIS 95
Krasovsky spheroid (ellipsoid) A reference ellipsoid having the following approximate dimensions: semimajor axis 6,378,245.0 meters; flattening or ellipticity 1/298.3. HDBK-850
KVR-1000 Camera [Russian] The KVR-1000 camera employs a 1000mm lens. This camera provides 2 meter resolution panchromatic imagery at an average scale of 1:220,000. The format is 18 cm with single frame coverage of 40 km by 180 km but imagery is available in sub-frames. The data is single band with a spectral range of 510-760 nm. The KVR-1000 images are registered to the TK-350 images for precision overlaying of the two images. This makes the camera systems ideal for precision base mapping and wide area coverage applications.
