Swiss Coordinate System
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 ( Swisstopo). A first coordinate system was introduced in 1903 under the name LV03 (''Landesvermessung 1903'', German for “land survey 1903”), based on the Mercator projection and the Bessel ellipsoid. With the advent of GPS technology, a new coordinate system was introduced in 1995 under the name LV95 (''Landesvermessung 1995'', German for “land survey 1995”) after a 7-year measurement campaign. LV03 Introduced in 1903, this first geographic coordinate system rested upon the two dominant methodological pillars of geodesy and cartography at the time: the Bessel ellipsoid and the Mercator projection. Its measurements used the Bessel ellipsoid as an approximation of the Earth's shape, and its maps used the Mercator projection as a projection technique. Although not ideal, these approximations ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Engadin
The Engadin or Engadine ( rm, ;This is the name in the two Romansh idioms that are spoken in the Engadin, Vallader and Puter, as well as in Sursilvan and Rumantsch Grischun. In Surmiran, the name is ''Nagiadegna'', and in Sutsilvan, it is ''Gidegna''. german: ; it, Engadina; french: Engadine) is a long high Alpine valley region in the eastern Swiss Alps in the canton of Graubünden in southeasternmost Switzerland with about 25,000 inhabitants. It follows the route of the Inn ( rm, En, links=no) from its headwaters at Maloja Pass in the southwest running roughly northeast until the Inn flows into Austria, little less than one hundred kilometers downstream. The En/Inn subsequently flows at Passau into the Danube, making it the only Swiss river to drain into the Black Sea. The Engadine is protected by high mountain ranges on all sides and is famous for its sunny climate, beautiful landscapes and outdoor activities.

Geographic Information System
A geographic information system (GIS) is a type of database containing Geographic data and information, geographic data (that is, descriptions of phenomena for which location is relevant), combined with Geographic information system software, software tools for managing, Spatial analysis, analyzing, and Cartographic design, visualizing those data. In a broader sense, one may consider such a system to also include human users and support staff, procedures and workflows, body of knowledge of relevant concepts and methods, and institutional organizations. The uncounted plural, ''geographic information systems'', also abbreviated GIS, is the most common term for the industry and profession concerned with these systems. It is roughly synonymous with geoinformatics and part of the broader geospatial field, which also includes GPS, remote sensing, etc. Geographic information science, the academic discipline that studies these systems and their underlying geographic principles, may also ...

Swiss Cartography
The cartography of Switzerland is the history of surveying and creation of maps of Switzerland. Switzerland has had its current boundaries since 1815, but maps of the Old Swiss Confederacy were drawn since the 16th century. The first topographical survey on a federal level began in 1809, resulting in the Topographic Map of Switzerland (German: ''Topographische Karte der Schweiz'') or ''Dufour Map'' (German: ''Dufourkarte''; French: ''Carte Dufour''). From 1869 to 1901, this map was replaced by the Topographic Atlas of Switzerland (German: ''Topographischer Atlas der Schweiz'') or ''Siegfried Map'' (German: ''Siegfriedkarte''; French: ''Carte Siegfried''). From 1901, the ''Topographical Survey of Switzerland'' is an independent division within the military, introducing the Swiss coordinate system in 1903. The office is renamed as the Swiss Federal Office of Topography in 1979, with thswisstopo.chwebsite online since 1997. Old Swiss Confederacy The first systematic geographical de ...

National Maps Of Switzerland
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 +). All maps are updated in a complete cycle of about six years. In 1938, the Federal Office of Topography started issuing new map sheets, which were intended to succeed the old Dufour and Siegfried Maps. They first appeared in 1:50,000 scale, and from 1952 also in 1:25,000 scale. In addition, further generalisations were made in smaller scales. In each scale, the whole of Switzerland was covered. In 1979, with the issuance of the last 1:25,000 scale sheet, the work was completed. The map sheets have been produced in several different versions: topographic maps, tourist maps, special maps (for aerospace, geology, etc.). They are now also availab ...

Swiss Border Guard
The Swiss Border Guard (french: Corps des gardes-frontière, german: Grenzwachtkorps, it, Corpo delle guardie di confine, rm, Corp da guardias da cunfin) was a federal law enforcement agency, which acted as both the border guard and customs service for Switzerland. It was a uniformed and armed section of the Federal Customs Administration, which is attached to the Federal Department of Finance. It was the largest civilian security agency on a federal level. Its members were subjected to military criminal law. The Swiss Border Guard took care of the prevention, intervention and repression concerning customs and migration related matters. It enforced border security and national compensating measures under the Schengen Agreement. The guard participated in international missions of the European Agency for the Management of Operational Cooperation at the External Borders (Frontex).

Swiss Armed Forces
The Swiss Armed Forces (german: Schweizer Armee, french: Armée suisse, it, Esercito svizzero, rm, Armada svizra; ) operates on land and in the air, serving as the primary armed forces of Switzerland. Under the country's militia system, regular soldiers constitute a small part of the military and the rest are conscripts or volunteers aged 19 to 34 (in some cases up to 50). Because of Switzerland's long history of neutrality, the Swiss Armed Forces do not take part in conflicts in other countries, but do participate in international peacekeeping missions. Switzerland is part of the NATO Partnership for Peace programme. The regulations of the Swiss militia system stipulate that the soldiers keep their own personal equipment, including all personally assigned weapons, at home (until 2007 this also included ammunition), or in an armoury. Compulsory military service applies to all male Swiss citizens, with women serving voluntarily. Males usually receive initial orders at the ...
