The foundations for quantitative map scaling goes back to ancient China with textual evidence that the idea of map scaling was understood by the second century BC. Ancient Chinese surveyors and cartographers had ample technical resources used to produce maps such as counting rods, carpenter's square's, plumb lines, compasses for drawing circles, and sighting tubes for measuring inclination.
The orthographic projection maps each point on the Earth to the closest point on the plane. Can be constructed from a point of perspective an infinite distance from the tangent point; r(d) = c sin d / R . [34] Can display up to a hemisphere on a finite circle.

This short street ends at the boundary of Gore Bay, at which point drivers must turn south to remain on the highway, which ends at a four-way intersection with Highway 540 and Highway 542.
In the 1959, Waldo Tobler published a paper titled "Automation and Cartography" that established the first use case for computers as aids in cartography. [7] In this paper, Tobler established what he referred to as a "map in–map out" (MIMO) system, which facilitated digitization of traditional maps, changing them, and reproducing them.
Consider two lattice points A and B separated by a translation vector r. Consider an angle α such that a rotation of angle α about any lattice point is a symmetry of the lattice. Rotating about point B by α maps point A to a new point A'. Similarly, rotating about point A by α maps B to a point B'.
Sanborn held a monopoly over fire insurance maps for the majority of the 20th century, but the business declined as US insurance companies stopped using maps for underwriting in the 1960s. The last Sanborn fire maps were published on microfilm in 1977, but old Sanborn maps remain useful for historical research into urban geography. The license ...
