Maps have been acting as a route guide for traveling a long distance since many years back. But the point arises from where the first sample of the map came.
So here are some of the earliest existence known examples related to maps
Babylonian Period Maps
In the form of Babylonian tablets or Egyptian land drawing and painting discovered in early tombs. In 1961 a town plan of Catalhoyuk in Turkey was unearthed, painting on a wall. Featuring houses and the peak of a volcano, it is around 8500 years old.
Similarly, the sixth-century tablet known as Imago Mundi shows Babylon on the Euphrates, with cities on a circular landmass, surrounded by a river. Some maps are known as T and O maps. In one, illustrating the inhabited world in Roman times, T represent the Mediterranean, dividing the continents, Asia, Europe, and O is the surrounding ocean, the T and O Hereford Mappa Mundi of 1300, drawn on a single sheet of vellum, include writing in black ink and water painting green, with the red sea colored red.
Greek Period Maps
Greek scholars developed a spherical earth theory using astronomical observation, and in 350 B.C.E. Aristotle produced arguments to justify this practice. In the first century C.E., Ptolemy, an astronomer, and mathematician developed a reference –line principle. His guide to geography lists 8,000 locations with their approximate latitudes and longitudes.
However, Ptolemy underestimates the size of the earth. His suggestion that India could be reached by traveling westward resulted in Columbus underestimating the distance centuries later, cartography greatly benefited from a wealth of corrective information brought to Europe by Marco Polo in the thirteenth century.
International Geographical Congress
The 1891 international geographical congress established specification for a scale map of the world, and world war 1st and 2nd brought more progress.
