Industry:Earth science
The hiding of incorrectly scribed features, scratches, and other undesirable marks by painting over the lines with an opaque liquid using a fine brush.
Industry:Earth science
A plane curve defined (a) geometrically as the locus of all points for which the distance from a fixed line (called the directrix) is equal to the distance from a fixed point (called the focus), and defined (b) algebraically as the set of points whose coordinates satisfy the equation y = ax², in which a is a constant. The two definitions are equivalent. The parabola's principle use in surveying is as a transition curve.
Industry:Earth science
Triangulation in which the sides of triangles are from a few meters to a few hundreds of meters long.
Industry:Earth science
A set of linear equations between two vectors x and y, y = Ax + b, which is solvable for x in terms of y, the matrix A and the constant b. This usage is misleading and, like observable (3) appears to be used as jargon by some statisticians.
Industry:Earth science
The parallax of a star determined from those differences in stellar spectra which depend upon the pressure in the star's atmosphere. Atmospheric pressure can be used to determine, from theory, the star's luminance, the absolute magnitude and finally the distance.
Industry:Earth science
That line, on a photograph, which is the image of a straight line in object space, passes through the principal point and is perpendicular to the principal plane.
Industry:Earth science
Those planets which lie farther from the Sun than Mars: Jupiter, Saturn, Uranus, Neptune and Pluto.
