Natural Earth describes the entity as a "1 meter square island" with "scale rank 100, indicating it should never be shown in mapping". [7] The name "Null" refers to the two zero coordinates, as null values (indicating an absence of data) are often coerced to a value of 0 when converted to an integer context or "no-nulls allowed" context.
This is a list of places on land below mean sea level.. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included.
This is a difference of less than one millimetre (0.039 in) over the total distance (approximately 1.86 kilometres or 1.16 miles). Earth is commonly modeled as a sphere flattened 0.336% along its axis. This makes the Equator 0.16% longer than a meridian (a great circle passing through the two poles).
[a] This great circle divides the Earth into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. [1] Earth's current international standard prime meridian is the IERS Reference ...
0° or 0 degrees may refer to: Longitude: the prime meridian on any planet or moon . For most of the 20th century on Earth, the prime meridian (Greenwich); IERS Reference Meridian, the modern reference meridian for time and global navigation on Earth
Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth.

Generally speaking, only a few regions of the dry-land part of the Earth are so remote or have such a harsh climate that no one uses those areas for even part of the year. These places are tiny islands, the driest part of large deserts, very high mountains, and ice caps.
