The difference in time or height of a high or low water, as these occur at a reference station and a subordinate station (reference tide gage and subordinate tide gage). The difference is applied to the time or height determined at the reference station to obtain the corresponding quantity at the subordinate station. These differences are available in tables of the tides.

Industry:Earth science
Radial distortion calculated so as to minimize the errors in locations of individual image points with respect to each other.
Industry:Earth science
One of three angles specifying the direction of a line with respect to the three axes of a Cartesian coordinate system in 3 space by specifying the angle between that line and each of the three axes. The three angles are not completely independent, but unless the quadrant in which the line lies is known, three angles must be given to avoid ambiguity.
