arbitrary method of adjusting a traverse
Earth science; Mapping science
Corrections are applied to the measured quantities (or to the calculated components of these) according to the surveyor's analysis of conditions that prevailed along the traverse. i.e., the ...
right ascension
Earth science; Mapping science
The angle between the plane of the hour circle passing through a celestial body and the plane of the hour circle passing through the vernal equinox. It is measured eastward from the vernal equinox ...
autocollimator
Earth science; Mapping science
A telescope containing illuminated crosshairs placed so that they are imaged, by the objective lens system, at infinity (i.e., light from it is collimated by the objective lens system). When the ...
Bache Wurdeman Base Line Apparatus
Earth science; Mapping science
A compensating base line apparatus composed of a bar of iron and a bar of brass, each a little less than 6 meters in length, held together firmly at one end, with the free ends so connected by a ...
annual aberration
Earth science; Mapping science
That apparent change in direction of a star, planet, or other celestial body which is caused principally by the Earth's revolution about the Sun. That part of stellar aberration which has an annual ...
vectorial angle
Earth science; Mapping science
(1) A vector which has a length is equal to the magnitude of a given plane angle and which is directed so that it is perpendicular to the plane of that angle and in a sense so as to form a right ...
bathymeter
Earth science; Mapping science
An instrument used for determining depths of the oceans or other deep bodies of water. There are a number of designs of such instruments. The principal ones are the lead line and the echo ...
