Hekatæus of Miletus (550–475 BC) produced another map fifty years later that he claimed was an improved version of the map of his illustrious predecessor. The world according to Hekatæus, 500 BC. Hecatæus's map describes the Earth as disk with an encircling Ocean, and with Greece placed in the center.
The Gangnido ("Map of Integrated Lands and Regions of Historical Countries and Capitals (of China)") [34] is a world map and historical map of China, made in Korea in 1402, although extant copies, all in Japan, were created much later.
This argument was put forward by the geographer Strabo (c. 64 BC – 24 AD), who suggested that the spherical shape of Earth was probably known to seafarers around the Mediterranean Sea since at least the time of Homer, [39] citing a line from the Odyssey [40] as indicating that the poet Homer knew of this as early as the 7th or 8th century BC.

The projection found on these maps, dating to 1511, was stated by John Snyder in 1987 to be the same projection as Mercator's. [6] However, given the geometry of a sundial, these maps may well have been based on the similar central cylindrical projection, a limiting case of the gnomonic projection, which is the basis for a sundial. Snyder ...

The system has not been directly adopted, but some maps divide the world into 24 time zones and assign letters to them, similarly to Fleming's system. [21] World map of time zones in 1928. By about 1900, almost all inhabited places on Earth had adopted a standard time zone, but only some of them used an hourly offset from GMT.
The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [3] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
