condlllon aqusstlo*A set of adjustment
e~afkms wherein afl variables representing
parameters heve bean eliminated hum the
equations, leaving only variables representing
the acfjusfmatis to the observed quantities in
the equations. A least squares adjustment
e~ying this type of equations is said to be by
fhe mmliiicn melhod, as opposed 10 the
obaefvafion method or variallon ot parameters
method. Nole that it it is desired 10 albw a
previously established parameter to adjust,
ralher than hold if rigidly fixed, ii should be
mnsMerad as an observation with an
appropriate wefght. See also angle

cone engle bsndlng—Technique used in
-. analytical phologrammetry tor reducing
mensuration requirements on a ptrotographlc
plate by segregating Images into annular zones
defined by specific bands subtended, usualiy by
5“ of erc. Areas read are then only in certain
outer bands depending on the calibration of the
lens mne.
confidence intewal—A statement of
accuracy beesd on a statistic whose distribution
twwfion is known; e ,g., the normal distribution
function or bivarfate normal distribution function.
Errcva are sfatad ae some percentage of the
total probability of 100 percent; e.g., a 90
percent assurance level. Also called
aasurence level; arror Intanral;
probability Interval.
contlQuratlon management (CM)—A
procedure for applying technical and
admlntafrative dkaclbn and surveillance to (a)
klenttty and documem the tuncfional and
physical charecterist!cs of an Item or system, (b)
mnfrof any changes to such charecferistics and
(c) ramrzf and report the change, process, end
lmpfementatbn status, The CM process must
be carefully telbrad fo the capacity, size scope,
and phase of Ihe Me cycle, nature and
Complextiy of the system Involved.

conforfrral map projection-A map
pro@tbn on which Ihe ehapa of any emall area
of lha surtaca mapped is preserved unchanged,
arxf all angles around any point are mfredty
represented. Also celled orfhomorphlc SISap

conic cherf with two standard parallela—
A chart on the mnic pfojacflon with SW standard
parallels. Also called S@Cant Conic chart.

conic map projection wl!h two standard
paraflela-A conic map projection in which lhe
surface of a sphere or spheroid, such aa the
Earth, is conceived as developed on a cons
which inlarsects tha sphere or spheroid atong
two standard parallels. The Lambd conformal
projection is an example. Also called ●ecent
corslc map pro]ectlons.
conic map projactlon—A map projection
produced by projecting the geographic
mer”tiians and parallels omo a mne whtch ie
tangam to (or intersects) tha wrlasa of a
sphere, and then davebping the mrra thto a
plane. Conic map projections may be
wnsidered as including cylindrical map
projection when the apex of the mne is at an
infinite distance from the sphere, and
projections on a tangem ptane when that
distanca la zero. Conic map pmjactbns may be
Illustrated with a single mne which is tangent to
Ihe sphare or which cuts the sphere abrrg two
parallals; or they may be a series of tangent
cones. all with apexes on an extenabn of the
axis of the sphare, at mnstantty incraasi~ (or
decreasing) distancas from tha sphere. Itis best
ueed to show areas of large bngitudlnal rather
than latitudinal distances. Also called tanOant
conical map projection.
