graticule
See Also: grid, latitude, longitude
[cartography] A network of longitude and latitude lines on a map or chart that relates points on a map to their true locations on the earth.
Graticules
Creating a grid across the view can help to better reference the view. This can be especially important when printing out a map for later use.

Graticule The designated grid of parallels and meridians on the earth and a map.
The Graticule as a Guide to Distortion
Especially for a map in the normal aspect, a quick visual inspection of its graticule provides obvious clues of whether its projection preserves features.
Graticule figures:
The graticule figures (values) are positioned automatically in the border, adjacent to the graticule ticks ...
Graticules are lines of Longitude and Latitude. These never form a square or rectangular shape and their shape changes dramatically from the Equator to the Pole - from being close to square shaped to being close to triangle shaped.
Graticule
The pattern created by intersecting lines of latitude and longitude (parallels and meridians). This configuration makes several assumptions about the shape of the globe, most notably that it is a perfect sphere.

Graticule - The grid of latitudes and longitudes drawn on a map or a globe.
GRS80 (Geodetic Reference System of 1980) - A standard defining the size and shape of the Earth as adopted by the International Union of Geodesy and Geophysics in 1979.
The graticule represents the projected position of the geographic coordinates at constant intervals, or in other words the projected position of selected meridians and parallels.
But their combination as a gridded network called a graticule is enormously useful. Picture a perfectly spherical grid generally holding a rough, imperfect ball; sometimes the perfect grid lies outside the ball, sometimes under its surface.
The first is called "Calculations involved in preparing a grid of graticule" and is heavily math oriented, containing formulas for several projections. The second section is concerned with accurately drawing a graticule manually.
system of lines on a plane representing a corresponding system of imaginary lines on an adopted terrestrial or celestial datum surface. Also, the mathematical concept for such a system. For maps of the Earth, a projection consists of 1) a graticule ...
This generally requires a systematic mathematical transformation of the earth's graticule of lines of longitude and latitude onto a plane.
US military maps and charts include a graticule (parallels and meridians) for plotting and scaling geographic coordinates. Graticule values are shown in the map margin.
Although the method of construction is not explained by the author, Mercator probably used a graphical method, transferring some rhumb lines previously plotted on a globe to a square graticule, ...
The grid formed by the latitude and longitude on a map is called the graticule. There are thousands of different map projections all depending on how they intersect earth's surface and how they are oriented.
If a map depicts a graticule (a network of longitude and latitude lines), then cartographic convention dictates that whenever possible, the type should be placed parallel with the lines of latitude.
Automatic grid and graticule generation and support for a variety of marginalia are included in Bentley Map V8i.
Grid Manager is a suite of tools that helps you create multiple grids, graticules, and borders for a variety of map products including nautical, aeronautical, topographic, parcel, street, and tourist maps.
Why Use Grid Manager?
The problem apparently is that projections distort distances differently at different locations. The stretching of the regular latitude graticule in this image is testimony to the Mercator's huge distortion at northern latitudes.
GEOREFERENCE SYSTEM
A CO-ORDINATE SYSTEM for points on the Earth's surface. Examples of such a system are the Universal Transverse Mercator system (UTM) and the latitude and longitude graticule.
These coordinate values represent locations you could locate using the numeric values printed on the graticule on the edges of a paper map. The storage of real-world coordinate values for features stored in the GIS is known as georeferencing.
That is, use the fact that the value at any location is the average of its neighbors. For this purpose a weighted average of the neighbors must be used because the neighbors are at different spherical distances in the latitude/longitude graticule.
