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 ...

A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection. [1]
This draft guideline was created to provide wikipedians with basic instruction and advanced techniques in using coordinate-referenced map templates to generate maps in wikipedia articles. For the purposes of this article, Geolinks can be defined as links to commercial maps using geographical coordinates.
A property survey legally defines the boundaries of a plot of land. Mortgage lenders and/or title companies may require one when you're buying a house. You may also need one when making certain ...
EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, originated by a member of the European Petroleum Survey Group (EPSG) in 1985.
In constructing a map on any projection, a sphere is normally chosen to model the Earth when the extent of the mapped region exceeds a few hundred kilometers in length in both dimensions. For maps of smaller regions, an ellipsoidal model must be chosen if greater accuracy is required; see next section.
Allows 'OSM ExternalData elements' to be added to the map. This can be an administrative boundary, highway or other linear map element that has been assigned a wikidata Q value. (e.g.: map-data=Q83065 will add the city boundary of Leicester.) The map item needs to be on the same place as the map itself.
