The principal survey and mapping organization in Norway
is Statens kartverk (SKV), Hønefoss. Formerly known as
Norges Geografiske Oppmåling, it was established under its
present name in 1986 to be responsible for the country's
land, sea and resource mapping. The original topographic
survey was founded in 1773, but the first systematic
mapping program did not commence until 1867 with
the establishment of a national plan for mapping, which
included the provision of a 1:100,000 scale series known as
the rektangelkart, and drawn on a Cassini projection. Later,
in northern Norway, the gradteigskart (graticule map) was
introduced, also at 1:100,000 scale but on a Polyhedric
projection (later transferred to the Gauss-Krϋger). The four-color
maps of these two series, drawn originally from plane
table and aneroid surveys, eventually covered most of
Norway and remained in production until 1966.
The 1:50,000 (Series M711) forms the basic scale modern map
of Norway. Work on this series began in 1955, when sheets
of northern Norway were compiled to NATO specifications
with the aid of the American Defense Mapping Agency. The
current map covers the whole of Norway in 727 sheets.
The latest sheets are printed in seven colors, and there is
a 20 m contour interval. The projection is UTM, and a 1 km
UTM grid is printed on the face of the map in blue. The
series now uses the EUREF89 (WGS84) datum. The legend
is in Norwegian and English, and the map is available in
flat or folded formats. It is kept up-to-date using aerial
photogrammetric methods and fieldwork, and revision material
is sometimes added to the sheets as a magenta overprint.
Editions published since 1988 show cultivated land
in yellow. Following the passing of a place name law in
1991, the maps are to become official records of the approved
(standardized) names. The more recent sheets are printed
with an integral cover and an index of place names on the
reverse. The map sheets are graticule-based, each covering
15' of latitude, but varying in east-west extent from 22.5'
of longitude in the south to 36' in the north. A complete
set of the 727 sheets may be purchased in three volumes.
Soviet military topographic mapping of Norway is available at the following scales: 1:1,000,000 (9 sheets, complete coverage, published 1980-1988);
1:500,000 (22 sheets, complete coverage, published 1976-1987); 1:200,000 (105 sheets, complete coverage, published 1974-1990); 1:100,000 (330 sheets, complete coverage,
published 1969-1999) and city (1:10,000) topographic mapping of Kristiansand, Narvik, Stavanger and Tromsø published between 1975 and 1989. These products are available in print,
digital raster and digital vector GIS formats from East View Geospatial.
