Blake is a surname or a given name which originated from Old English. Its derivation is uncertain; it could come from "blac", a nickname for someone who had dark hair or skin, or from "blaac", a nickname for someone with pale hair or skin. Another theory is that it is a corruption of "Ap Lake", meaning "Son of Lake".

Blake was the name of one of the 14 Tribes of Galway in Ireland. These Blakes were descendants of Richard Caddell, alias Blake, who was involved in the Norman Invasion of Ireland in 1169.

The Origins of the name Blake is also considered to be Old Norse first appearing in England Yorkshire, possibly derived from the word Blaker referring to a village and a former municipality of Akershus county, Norway (east of Oslo).

Blake often refers to the British poet, painter and printmaker William Blake (1757–1827) or to the contemporary figurative artist Blake (sculptor).

A map is a visual representation of an area—a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes.

Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping, and extraterrestrial mapping.

Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography), and one who makes maps is called a cartographer.

Road maps are perhaps the most widely used maps today, and form a subset of navigational maps, which also include aeronautical and nautical charts, railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by municipalities, utilities, tax assessors, emergency services providers, and other local agencies. Many national surveying projects have been carried out by the military, such as the British Ordnance Survey (now a civilian government agency internationally renowned for its comprehensively detailed work).
