Grids and Graticules include reference grids, measured grids and graticules
This "double-barrelled" tag has been created to help disambiguate questions on reference grids, measured grids and graticules from those on grids when used as a term for raster datasets.
In Cartography it is 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.
