Mapping science
skew angle
Earth science; Mapping science
(1) The acute angle between a line perpendicular to one center-line and to another center line. (2) The amount of angle by which that two intersecting lines deviate from a right angle.
augmentation
Earth science; Mapping science
(1) The number of times the apparent topocentric, angular diameter of a celestial body is greater than the geocentric, angular diameter of that body. (2) The apparent increase in diameter of a ...
parallactic angle
Earth science; Mapping science
The angle, on the celestial sphere, between a great arc from a heavenly body to the pole and a great arc from the celestial body to the observer's zenith. It should not be confused with parallax.
aiming circle
Earth science; Mapping science
A theodolite of low accuracy with limited amount of rotation vertically, a low power telescope, and containing a magnetic compass. Aiming circles used by the artillery have been graduated in mils. ...
apo
Earth science; Mapping science
(prefix) Farthest from the attracting body. e.g. apogee, that point, in the elliptical orbit of a terrestrial satellite, at which the satellite is farthest from the Earth. But aphelion, not ...
normal-section azimuth
Earth science; Mapping science
The angle at a point A, on the ellipsoid, between the meridional plane through A and the normal section which passes through A and B.
Astro Gravimetric Method Of Determining The Geoid
Earth science; Mapping science
A method of determining geoidal heights from deflections of the vertical calculated from gravimetric data, or from a combination of gravimetric and astronomic data.
