Lake Zurich is a lake in Switzerland, extending southeast of the city of Zürich. Depending on the context, Lake Zurich or Zürichsee can be used to describe the lake as a whole, or just that part of the lake downstream of the Seedamm at Rapperswil, whilst the part upstream of Rapperswil may be called the Obersee or Upper Lake.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system.
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs.
Topography is the study of the forms and features of land surfaces. The topography of an area could refer to the land forms and features themselves, or a description.
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults, folds, are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
Swisstopo is the official name for the Swiss Federal Office of Topography, Switzerland's national mapping agency.
The Swiss coordinate system is a geographic coordinate system used in Switzerland and Liechtenstein for maps and surveying by the Swiss Federal Office of Topography (Swisstopo).
Ordnance Survey of Northern Ireland (OSNI) was the official mapping agency of Northern Ireland. The agency ceased to exist separately on 1 April 2008 when it became part of Land and Property Services, an executive agency of the Northern Ireland Department of Finance and Personnel, along with the Rate Collection Agency, the Valuation and Lands Agency, and the Land Registry.
Trübsee is an intermediate cable car station by the Titlis Bergbahnen, Trüebsee is an Alpine lake on the Ober Trüebsee Alpine pasture in the upper part of the extensive municipality of Wolfenschiessen in the Swiss canton of Nidwalden. The lake lies at the foot of the Titlis above the village resort of Engelberg. It can be reached from the village by cable car, or via several alpine walking paths, e.g. the Pfaffenwand.
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 or Dufour Map. From 1869 to 1901, this map was replaced by the Topographic Atlas of Switzerland or Siegfried Map.
The Dunantspitze, formerly called Ostspitze, is a peak of the Monte Rosa Massif in the Pennine Alps in Switzerland. It is the second highest peak of the massif, after the Dufourspitze (4,634 m) and the second highest summit in Switzerland, but its prominence is only about 15 metres. At the time of its first ascent it was unclear which of the summits was the higher.
An orienteering map is a map specially prepared for use in orienteering events. It is a large-scale topographic map with extra markings to help the participant navigate through the course.
Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose, which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015 Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Business, Energy and Industrial Strategy. It was also a member of the Public Data Group.
A national mapping agency is an organisation, usually publicly owned, that produces topographic maps and geographic information of a country. Some national mapping agencies also deal with cadastral matters.
The Topographic Atlas of Switzerland, also known as the Siegfried Atlas or Siegfried Map is an official map series of Switzerland. Its publication was begun by the Federal Topographic Bureau under Hermann Siegfried, and continued from 1870 to 1926. During this period the individual maps were drawn by different lithographers, including Walter Hauenstein, Georg Christian von Hoven and Rudolf Leuzinger. Since it is, in today's parlance, not strictly an atlas but a map series, map historians now describe it only by the expression Siegfried Map.
A map series is a group of topographic or thematic charts or maps usually having the same scale and cartographic specifications, and with each sheet appropriately identified by its publisher as belonging to the same series.
A map collection or map library is a storage facility for maps, usually in a library, archive, or museum, or at a map publisher or public-benefit corporation, and the maps and other cartographic items stored within that facility.
The Scheidegg is a mountain summit of the Rigi massif, overlooking Goldau in the canton of Schwyz on its north mountainside, and Gersau and the Gersauerbecken on its south side. The cable car station 160 metres east of it is called Rigi Scheidegg.
