Non-harmonic tidal constant
Earth science; Mapping science
A tidal constant other than a harmonic tidal constant, e.g., the range of an interval derived directly from measurements of high water and low water.
Anomalistic tidal cycle
Earth science; Mapping science
The average period, of about 27½ days, measured from perigee to perigee, during which the Moon completes one revolution around the Earth.
Algebraic curve
Earth science; Mapping science
(1) The set of points in N-space satisfying a polynomial equation in N variables. In particular, the set of points, in the plane, satisfying a polynomial equation in two variables.
Contrast transfer function
Earth science; Mapping science
A function giving the variation of contrast transfer factor with frequency.
Coordinate cadaster
Earth science; Mapping science
A cadaster specifying the boundaries of a region by the coordinates of points on these boundaries.
Complete datum
Earth science; Mapping science
A datum containing exactly all the constants needed for specifying the coordinate system used. By definition, all geodetic datums (in sense (1)) are complete datums. However, the term datum is ...
Contrast transfer curve
Earth science; Mapping science
A curve showing the relative contrast in the photographic image of a square wave or progressive square wave pattern as a function of the nominal spatial frequency of the pattern. i.e., a curve ...
