The division of Earth by the Equator and the prime meridian Map roughly depicting the Eastern and Western hemispheres. In geography and cartography, hemispheres of Earth are any division of the globe into two equal halves (hemispheres), typically divided into northern and southern halves by the Equator and into western and eastern halves by the Prime meridian.
The land hemisphere and water hemisphere are the hemispheres of Earth containing the largest possible total areas of land and ocean, respectively. By definition (assuming that the entire surface can be classified as either "land" or "ocean"), the two hemispheres do not overlap. Determinations of the hemispheres vary slightly.

Western Australia in the west third with capital Perth, Northern Territory in the north center with capital Darwin, Queensland in the northeast with capital Brisbane, South Australia in the south with capital Adelaide, New South Wales in the northern southeast with capital Sydney, and Victoria in the far ...
The almost perfect circle (the earth is an oblate spheroid that is wider around the equator), drawn with a line, demarcating the Eastern and Western Hemispheres must be an arbitrarily decided and published convention, unlike the equator (an imaginary line encircling Earth, equidistant from its poles), which divides the Northern and Southern hemispheres.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Earth's western hemisphere showing topography relative to Earth's center instead of to mean sea level, as in common topographic maps. Earth has a rounded shape, through hydrostatic equilibrium, [86] with an average diameter of 12,742 kilometres (7,918 mi), making it the fifth largest planetary sized and largest terrestrial object of the Solar ...
An example of a cartographic style guide for a particular institution, including typography standards. Typography, as an aspect of cartographic design, is the craft of designing and placing text on a map in support of the map symbols, together representing geographic features and their properties.
World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.7″) and the Arctic Circle (66°33′50.3″) in the northern hemisphere and ...
