NATIONAL REPORT ON SWEDEN 
by 
B. Hallert. 
During the four years that have passed since the congress in the Hague, 
Swedish photogrammetry has been steadily developing. A brief summary of 
this development is given in a paper “Fotogrammetriska meddelanden” Volu 
me II, No. 2 1952 that is distributed for this congress. 
About 70 papers on different photogrammetric themes have appeared in 
Sweden during the period. 
Aerial photogrammetry for topographic purposes has undergone a consid 
erable development as well in the Geographical Survey Office as in the Land 
Survey Board. Especially of interest is the development of aerial photogram 
metry to a regular method for cadastral survey purposes. 
A considerable number of public and private organizations use to day 
aerial photographs and maps produced on the basis of them. 
Also special photogrammetry for other purposes than topographic sur 
veying has developed considerably during the period. The chief investigations 
have been made by the Committee on Forestry Photogrammetry and the Divi 
sion of Photogrammetry at the Royal Institute of Technology in Stockholm. 
The photogrammetric research has to a great deal been performed in con 
nection with the development of photogrammetry in different organizations. 
At the Royal Institute of Technology in Stockholm the divisions of Photo 
graphy and Photogrammetry and the provisorically founded Optics Labora 
tory work in close cooperation. For military purposes there is an increasing 
photogrammetric activity in the Department of Photography at the General 
Staff of Defense and Air Force Administration. 
Photogrammetric education is mainly given by the Institute of Photogram 
metry at the Royal Institute of Technology. Special courses have been organi 
zed for land surveyors, foresters and dentists. 
The Swedish Society of Photogrammetry has about 160 members. A con 
siderable international cooperation has developed during the period. Valuable 
lectures have been given by foreign photogrammetrists from England, Finland, 
France, Germany, Italy, and Switzerland. Such lectures are very much appre 
ciated in Sweden and I will use this opportunity to invite photogrammetrists 
from all countries to visit us and inform us on their activity and problems. 
I will end this very brief summary in bringing over the best wishes and 
regards from Swedish photogrammetrists to their colleagues from other 
countries.
