Founded in 1941, the American Congress on Surveying and Mapping (ACSM) is an international association representing the interests of professionals in surveying, mapping and communicating spatial data relating to the Earth's surface. Today, ACSM's members include more than 7,000 surveyors, ...
(1) Ziemia pod mokrą, lepką postacią, jak błoto. (2) Ziemisty, bardzo plastyczny osad składający się z dużej ilości wodnych krzemianów w postaci drobno zmielonych koloidalnych lub glinianych cząstek.
Industry:Earth science
The increase in volume of a continuous material per unit volume of the material. For example, local dilatation of the crust has been found to be a precursor of some earthquakes.
Industry:Earth science
Those dimensional changes in length and width of film, paper, etc. , which deform photographic or printed images.
Industry:Earth science
The vertical angle, at the eye of an observer, between the horizontal plane there and a straight line tangent to the surface of the Earth. It is larger than the dip of the horizon by the amount of the terrestrial refraction.
Industry:Earth science
(1) A thin, opaque piece of material with a hole through which light can pass and placed in an optical system to keep unwanted light from reaching the image plane or detector e.g., to limit the field of view or to absorb internally scattered light. The stop is the theoretical counterpart of the diaphragm. A shutter is a diaphragm whose opening can be open or closed, usually in a specified interval of time. The mechanism that does the opening and closing is sometimes called the shutter mechanism but is also often considered, together with the diaphragm, to constitute the shutter. (2) The thin disk of glass on which lines forming a reticle are placed. However, the term reticle is often used to denote both the diaphragm and the lines.
Industry:Earth science
The method of adjusting a survey traverse by using the directions (azimuths) of courses as the measured quantities.
Industry:Earth science
(1) The distance along a surveyed line from a survey station or the last whole numbered survey point to a supplementary point. For example, if a stake is set at 515. 56 feet from the initial point of a surveyed line and is does not mark the end of that line, the whole numbered 500-foot point on the line is station No. 5; the stake is a plus station (No. 5+15. 56), and the 15. 56 is a plus distance. (2) A fractional part of the length of a course from the beginning of the course to a specified point on the course.
Industry:Earth science
The angular diameter, usually measured in seconds of arc, of a celestial body as the body would appear if viewed from the center of the Earth.
Industry:Earth science
That digit, in a number, which contributes least to the value of the number.
Industry:Earth science
A map showing the geographic occurrence of a specific product, commodity, or formation. The map may show merely that the product, etc. , occurs in certain regions, or it may also show how much is produced or occurs there.
