Industry:Earth science
One of a pair of short lines drawn at the opposite edges of a map and perpendicular to the edges, indicating that the line of a grid extends between these marks. In other words, grid ticks are those parts of a grid left after most of each line between the edges of the map has been removed. They are usually used when another system of lines such as a graticule is to be shown in full on the map.
Industry:Earth science
A grid, quadrillage or system of rectangles associated with rectangular coordinates, referred to a single origin, and superposed on and extending over the whole of a map. A military grid is intended to make it easier to obtain coordinates of points on a map.
Industry:Earth science
The temperature at which a mixture of pure, air saturated water, and ice can exist in equilibrium under a pressure of one standard atmosphere.
Industry:Earth science
A graduated ring fitted to a globe so that the plane of the ring contains the center of the globe and is adjustable to be parallel to the horizontal plane for any point on the globe. The horizon ring is used for measuring angles around the horizon at a given point.
