Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. Geophysicists, who usually study geophysics, physics, or one of the Earth sciences at the graduate level, complete investigations across a wide range of scientific disciplines. The term geophysics classically refers to solid earth applications: Earth's shape; its gravitational, magnetic fields, and electromagnetic fields ; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.
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.
Hans Island is an island in the centre of the Kennedy Channel of Nares Strait in the high Arctic region, split between the Canadian territory of Nunavut and the Danish autonomous territory of Greenland. The island itself is barren and uninhabited with an area of 130 hectares, measuring 1,290 by 1,199 metres, and a maximum elevation of 168.17 m (551.7 ft). Its location in the strait that separates Ellesmere Island of Canada from northern Greenland was for years a border dispute, the so-called Whisky War between the two countries of Canada and Denmark. Hans Island is the smallest of three islands in Kennedy Channel off the Washington Land coast; the others are Franklin Island and Crozier Island. The strait at this point is 35 km (22 mi) wide, placing the island within the territorial waters of both Canada and Denmark (Greenland). A 1,280-metre-long (4,200 ft) border traverses the island.
Møllehøj is the highest natural point in Denmark at 170.86 m (560.6 ft).
Geodætisk Institut (1928–1987) was a Danish state-run cartographic institute.
Ministry of the Environment of Denmark is the Danish ministry in charge of almost all matters concerning environmental issues in Denmark. The head office is in Copenhagen.
The Danish Ministry of Climate, Energy and Utilities is a governmental agency in Denmark. It is responsible for national climate policy and international cooperation on climate change, as well as energy issues, meteorology and national geological surveys in Denmark and Greenland.
The King Sejong Station is a research station for the Korea Antarctic Research Program that is named after King Sejong the Great of Joseon (1397–1450).
The Norwegian Mapping Authority (NMA) is Norway's national mapping agency, dealing with land surveying, geodesy, hydrographic surveying, cadastre and cartography. The current director is Johnny Welle. Its headquarters are in Hønefoss and it is a public agency under the Ministry of Local Government and Regional Development. NMA was founded in 1773.
The National Environmental Research Institute of Denmark, abbreviated NERI, was an independent research institute under the Ministry of the Environment. It was created in 1989 by merging the existing laboratories of the Environmental Protection Agency, which covered marine, freshwater and air pollution, soil ecology and analytical chemistry, with the Danish Wildlife Research, under the Ministry of Agriculture. The laboratories were physically located on Risø, in Silkeborg and on Kalø, north of Aarhus. In 1995, Greenland Biological Research laboratory was added.
The Earth Gravitational Models (EGM) are a series of geopotential models of the Earth published by the National Geospatial-Intelligence Agency (NGA). They are used as the geoid reference in the World Geodetic System.
A national mapping agency (NMA) 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.
UNAVCO was a non-profit university-governed consortium that facilitated geology research and education using geodesy.
Survey of Israel - SOI is the survey and mapping department of the Israeli Ministry of Housing and Construction. It is the successor of the Survey Department of Palestine, which existed in Mandatory Palestine between 1920 and 1948.
The Joint Arctic Command is a direct Level II authority in the Danish Defence. Joint Arctic Command's primary mission in peacetime is to ensure Danish sovereignty by monitoring the area around the Faroe Islands and Greenland. The command also handles tasks such as fisheries inspection, search and rescue (SAR), patient transport and other tasks that support the civil society. In short, the Joint Arctic Command handles military tasks, coast guard duties and disaster response - all in one organisation.
Geospatial Information Agency is the national mapping agency of Indonesia. BIG was formerly named National Coordinator for Survey and Mapping Agency. This national agency is responsible for Indonesian geospatial information per one map policy implementation. In 2010, Susilo Bambang Yudhoyono stated that Indonesia should have a single referenced map, so there would not be any differences in spatial data for country development.
Odinland, also Odinsland in the Defense Mapping Agency Greenland Navigation charts, is a peninsula in the King Frederick VI Coast, southeastern Greenland. It is a part of the Sermersooq municipality.
Margaretatop is a mountain in eastern Greenland. Administratively it is part of the Northeast Greenland National Park.
