Abstract: 
National report from Norway for the period 1988-1992, on photogrammetry, remote sensing, 
digital mapping and GIS. 
Key words: National Report 1992, Norway, NKTF. 
1. Introduction 
This report is prepared by Norges Karttekniske Forbund, NKTF, 
The Norwegian Association for Cartography, Geodesy and 
Photogrammetry. NKTF is the Norwegian member of ISPRS. 
The report gives a short introduction to the most important 
developments and changes during the 4-year period 1988-1992. 
The largest changes has taken place within digital mapping and 
GIS. 
2. Map-production in Norway 1988-1991 
Only the main map series are included in the following. 
2.1 Topographic map Norway 1:50000 (series M711) and 
related products 
The map series is produced by the Norwegian Mapping 
Authority (Statens Kartverk SK). The series consist of 727 
sheets, and were completed in the period. The yearly amount of 
revision is 35-40 sheets. 
A completely digital production line for the maps has been 
established. Up till now 28 sheets have been put into an "all- 
digital" form. 
A digital "names" database contains all the names from the 
maps, a total of 340000 names. The database was completed in 
1991, including a gazetteer. 
All contours, spotheights and water borders have been digitized 
and stored in databases. From these a DTM covering the whole 
of Norway has been generated. The grid size is approximately 
100x100m. The accuracy of the DTM is 6,5 meters RMSE, 
according to recent investigations. 
In 1990 the establishment of a digital road data bank was 
started. This is done from new aerial photography in scale 
1:40000. The accuracy requirements for position and height is 
+ 2m. The data are already used for planning of timber trans- 
portation, hopefully giving a reduction in costs of 20-30 million 
kroners a year when the database is finished. This database will 
also serve as the road part of the digital map database. 
2.2 Economic map of Norway, scales 1:5000 and 1:10000 
The Economic map of Norway is planned to cover 185000 km?, 
60% of the total land area. 163000 km? will be mapped in scale 
1:5000 and 22000 km” in scale 1:10000. By 1. january 1992 
more than 176000 km? had been mapped. According to present 
plans, the entire series will be completed by 1994. 
The updating is going on, but only densely populated areas can 
be handled. 
Digitizing the content of Economic map is in focus. At the 
moment 15% of the property-content has been digitized and put 
into a database. 
All new sheets and all updating are now made with digital 
output. 
2.3 Municipal maps, scale 1:500 - 1:2000 
Municipal maps are produced for local needs. The annual 
production within a community varies. The average annual 
production for Norway has been approximately 400kn for the 
scale range 1:500 - 1:1000 - 1:2000. All new maps are now 
digital. 
2.4 Norwegian polar mapping 
Norwegian Polar Research Institute is responsible for mapping 
the Norwegian Artic and Antarctic areas. 
Svalbard. The topographic main map series of Svalbard in 
scale 1:100000 is planned to cover the entire island group in 63 
sheets. By 1992 55 sheets had been constructed. 
Bjerngya. A new map in scale 1:50000 was issued in the 
period 1988-92. 
Jan Mayen. The island is covered by two sheets in scale 
1:50000. A new sheet in 1:100000 with revisions and a new 
datum has been issued lately. 
Bouvetgya. The island is covered by one sheet in scale 
1:20000.
