operators is on ıts way and that will certainly result 
in a constant supply of well trained personnel on 
the technician level. 
Research activities 
The research activities are first and foremost con- 
nected with the Royal Institute of Technology in 
Stockholm, where a well equipped photogrammetric 
division is working. During the past four years the 
main interest has been devoted to the burning prob- 
lems of accuracy incl. the theory of errors. Various 
applications have also received a lot of interest. A 
limiting factor has been a lack of competent and 
experienced research assistants as well as research 
students. The governmental and private photogram- 
metric organizations have been able to offer far 
better salaries and future chances due to their rapid 
expansion. 
An extensive applied research is performed by the 
»producing» photogrammetric organizations, first 
and foremost by the Geographical Office, the Land 
Survey Board and the Committee of Forest Photo- 
grammetry. This report does not deal with the ac- 
tivities connected with the two ISP-Subcommissions 
IV:1 and IV: 4 entrusted to Swedish photogram- 
metrists. 
The Swedish Society of Photogrammetry 
This society was founded in 1929 and is since then 
a member of the ISP. Its main purpose is—accord- 
ing to its statutes—to further the development of 
photogrammetry in Sweden e. g. through organiz- 
ing discussions and through distribution of reprints 
of papers and reports. The society arranges sessions 
with papers and discussions (the titles of the papers 
during the last four years is to be found in appen- 
dix 1) and around-the-table-discussions about actual 
problems e.g. the accuracy standards. No journal 
is published but reprints of interesting papers are 
distributed to the 205 individual and 10 coopera- 
tive members of the Society. 
OG SWEDEN 
The Society has taken over the responsibility for 
the remaining stock of the International Archives 
of Photogrammetry, Vol. XII, containing proceed- 
ings and papers from the VIIIth International Con- 
gress of Photogrammetry, held in Stockholm in 
July 1956. 
Swedish organizations actively engaged 
in photogrammetric work 
To give a certain idea about those organizations a 
few key-data are listed in appendix 2. Military 
organizations are not included. Those organizations 
which just buy the finished photogrammetric pro- 
ducts and take no part in its production are as well 
not included. Of course the dividing line between 
those two groups may be questionable. 
Bibliography for the period 
1/1 1956—31/12 1959 
The photogrammetric developments are usually pre- 
sented in papers in Swedish and foreign journals 
etc. but as space does not permit even abstracts we 
limit the presentation in this report to a condensed 
list of printed papers as appendix 3. 
Concluding statement 
This report is an attempt to present the status of 
Swedish photogrammetry in 1960 and what has 
happened between the Stockholm and the London 
congresses. The presentation is not complete and 
there has been no possibility to weight the various 
activities against each other. 
Swedish photogrammetry has consolidated its po- 
sition, the production facilities are pretty well 
dimensioned—except a lack of personnel, especially 
on university level—the interest in developments 
of methods and means is great within the govern- 
mental as well as within the private organizations. 
The international cooperation within the ISP, e. g. 
through its stimulating congresses every four year, 
has played an important róle in this evolution pro- 
cess.
