2.3.2 The Technical work of the Federation is handled by a
number of standing committees; these study such subjects as
urban renewal, rent and family incomes, professional town planners,
traffic problems, regional planning, and historic urban areas. A
very important publication by the Federation is a 'Glossary of
Planning Terms'a new edition of which is being prepared at the
present time.
2.4 International Society for Photogrammetry
2.4.1 The International Society for Photogrammetry (ISP),
was founded in 1910. It aims to link societies in various countries
or groups of countries together with individual members, public
authorities, institutes, business houses, for the purpose of furthering
photogrammetry and its allied subjects as well as its application
to science, technology and economics. 36 national societies or gov
ernment institutions representing 43 countries, together with a
few individuals make up its membership.
2.4.2 The technical work of the society is organised in a number
of technical commissions, each with a President and a Secretary
from a different member country. The commissions are: photo-
graphy and navigation; plotting theory and instruments; aerial
triangulationmapping from photographs; special applications;
education, terminology and bibliography; photo-interpretation.
Congresses are held every 4 years. The proceedings are published
as the 'International Archives of Photogrammetry'The periodical
for the society is entitled Photogrammetria' and is published
monthly.
2.4.3 One of the ideas discussed by Commission 6 of ISP (Edu
cation, terminology and bibliography) was that a means of access
to all information about previous experience available in some
form of publication was urgently needed by photogrammetrists.
In 1956 the International Training Centre for Aerial Survey at
Delft (Holland), whose present name is the International Institute
for Aerial Survey and Earth Sciences (ITC), offered its assistance
in the development of an abstracting service, and in 1958 the
'International Bibliography of Photogrammetry' began. It is pu
blished in the form of a card index with one card for the author of
an article, and one or more additional cards to represent all aspects
of the subject. The subject cards are filed according to the UDC.
The bibliography is trilingual, using English, French and German,
the three official languages of ISP. The organisation of the biblio
graphy is by means of voluntary unpaid international cooperation.
The photogrammetric society of each country undertakes to ab
stract books and selected articles from all periodicals which are
published in that country, and to forward them to ITC where
they are edited, classified, arid, if necessary, translated.
