USA MidwestMap01.png. Map of USA Midwest. Module:Location map/data/USA Midwest is a location map definition used to overlay markers and labels on an equirectangular projection map of USA Midwest. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Longitude lines are perpendicular to and latitude lines are parallel to the Equator. A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference ...
v. t. e. The Universal Transverse Mercator ( UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
Compass rose with the eight principal winds. A compass rose, sometimes called a wind rose, rose of the winds or compass star, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions ( north, east, south, and west) and their intermediate points. It is also the term for the graduated ...
Graticule (cartography) Map of Europe with a 30° graticule in dark gray. A graticule (from Latin crāticula 'grill/grating'), on a map, is a graphical depiction of a coordinate system as a grid of lines, each line representing a constant coordinate value. [1] It is thus a form of isoline, and is commonly found on maps of many kinds, at scales ...

Map of Tennessee (click on map to see larger image) Module:Location map/data/USA Tennessee is a location map definition used to overlay markers and labels on an equirectangular projection map of the U.S. state of Tennessee. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are named for René Descartes, whose invention of them in the 17th century revolutionized ...
