The Swiss coordinate system (or Swiss grid) is a geographic coordinate system used in Switzerland and Liechtenstein for maps and surveying by the Swiss Federal Office of Topography . A first coordinate system was introduced in 1903 under the name LV03 ( Landesvermessung 1903 , German for “land survey 1903”), based on the Mercator projection ...
The National Maps of Switzerland, also referred to as the Swisstopo maps, are a set of official map series designed, edited and distributed by Swisstopo, the Swiss Federal Office of Topography. Each map series is based on an oblique, conformal , cylindrical projection ( Mercator projection ), with a Swiss Coordinate system ( CH1903 + ).
The list of national coordinate reference systems (CRS) lists map projections officially recommended for existing countries. Given that every projection gives deformations, each country's needs are different in order to reduce these distortions.
Maps are useful in presenting key facts within a geographical context and enabling a descriptive overview of a complex concept to be accessed easily and quickly. WikiProject Maps encourages the creation of free maps and their upload on Wikimedia Commons. On the project's pages can be found advice, tools, links to resources, and map conventions.
Trüst's map shows most of the territory of modern Switzerland (but excluding Basel and Geneva). On the margins is a coordinate grid in Arabic numerals, using Ptolemy's prime meridian of 20°W. The first printed map of Switzerland is Tabula Nova Heremi Helvetiorum, published in the 1513 Strasbourg edition of Ptolemy. [2]
The HTML markup produced by this template emits an Geo microformat, which makes the location's coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map. As yet, the standard for doing this for off-world bodies is still under development, but is supported in some microformat parsers (e.g. Swignition ).
The Lambert azimuthal projection is used as a map projection in cartography. For example, the National Atlas of the US uses a Lambert azimuthal equal-area projection to display information in the online Map Maker application, [3] and the European Environment Agency recommends its usage for European mapping for statistical analysis and display.

The Topographic Map of Switzerland (German: Topographische Karte der Schweiz), also known as the Dufour Map (German: Dufourkarte; French: Carte Dufour) is a 1:100 000 scale map series depicting Switzerland for the first time based on accurate geometric measurements. It is also the oldest official map series of Switzerland.
