A series of hatchmarks along a layout, indicating geographical co-ordinates such as longitude and latitude.
A map projection is the systematic arrangement of the earth's (or generating globe's) parallels and meridians onto a plane surface. These meridians and parallels become the projection graticule.
The calibrated scale for quantifying information on a waveform monitor or vectorscope screen. The graticule can be silk-screened onto the CRT face plate (internal graticule), silk-screened onto a piece of glass or plastic that fits in front of the CRT (external graticule), or it can be electronically generated as part of the display.
Any circle on the surface of a sphere, especially when the sphere represents the Earth, formed by the intersection of the surface with a plane passing through the center of the sphere. It is the shortest path between any two points along the circle and therefore important for navigation. All meridians and the Equator are great circles on the Earth taken as a sphere
A grid of parallels and meridians on a map.
See coordinates, geographical (a).
a network of fine lines, dots, cross hairs, or wires in the focal plane of the eyepiece of an optical instrument
a spherical grid of coordinate lines over the planetary surface, comprising circles on planes normal (perpendicular) to the north-south axis, called parallels ( red ) and semicircular arcs with that axis as chord, called meridians ( blue )
A system of parallel lines or crossed lines at the telescope's focal plane, used in micrometers.
The designated grid of parallels and meridians on the earth and a map.
The network of longitude and latitude lines upon which a map is drawn.
Network of parallels and meridians on a map or chart.
The graticule is the spherical coordinate system based on lines of latitude and longitude.
The depiction of the lines of latitude and longitude on a map. The network of parallels and meridians plotted on the map in map projection. The lines will not be orthogonal or even, in general, straight.
A network of lines representing the earth's parallels of latitude and meridians of longitude.
The latitude and longitude grid drawn on a map or globe. The angle at which the graticule meets is the best first indicator of what projection has been used for the map.
The grid lines on a screen for measuring oscilloscope traces.
