L. Lindskog: Der Aus 
schuss für forstliche 
Photogrammetrie. 
(Pubi. VI L 2) 
»Der Ausschuss fiir forstliche Photogrammetrie», L. Lindskog, Schweden. 
Der Ausschuss ist im Jahre 1955 als freistehendes Organ eingerichtet. Seine 
Aufgabe ist, solche Fragen zu behandeln und klarzustellen, die mit der Ver 
wendung des Flugbildes in dem schwedischen Forstbetrieb Zusammenhängen. 
Der Ausschuss ist von dem Fonds für forstliche Forschung eingerichtet worden. 
Dieser Fonds finanziert auch die Tätigkeit des Ausschusses. 
Im Ausschuss haben verschiedene staatliche und private Fächer des Forst 
betriebs ihre Vertreter. Auch Behörden mit grösserer photogrammetrischer 
Tätigkeit sind da repräsentiert. 
Der Ausschuss hat eine Arbeitsgruppe, die vorläufig aus drei Beamten mit 
Ausbildung von Hochschulen besteht, von denen einer Vorsteher und Schrift 
führer ist. Ausserdem gibt es einen Assistenten ohne forstliches Hochschule- 
Examen und gelegentliche Arbeitskraft für Bearbeiten und Bureaugeschäfte. 
Das Arbeitsprogramm enthält Versuchs- und Forschungstätigkeit, Ausbildung 
und Auskunft nebst qualifizierter Hilfe von beschränktem Umfang. 
The Committee of Forest Photogrammetry 
The Committee is an independent body established in 1955 and has the task to deal with and 
settle questions concerning the utilization of air photos in Swedish forestry. The Committee was 
set up by the Fund for Forest Research which also finances its work. The Committee consists of 
representatives of different public and private branches of forestry and also representatives of 
some governmental departments with large photogrammetric activity. 
The Committee has a working group consisting of three officials with academic training. One 
of these is Manager and Secretary. Further there is an amanuensis and occasional employees for 
routine and office work. The working programme comprises experimental and research work, infor 
mation and training and in some instances the service of competent persons. 
D. Landen: New 
Developments in Photo 
grammetric Training 
for Geologists. 
(Publ. VI LI) 
Herr D. Landen war leider verhindert, seinen Vortrag »New Developments 
in Photogrammetric Training for Geologists» zu halten. Der Titel des Vor 
trages war von dem Präsidenten der Kommission gelesen. 
Within the U. S. Geological Survey many geologists have been applying cer 
tain photogrammetric techniques and using some of the less elaborate photo 
grammetric instruments in geologic mapping problems since 1930. Also, photo 
geology has been used in field and office procedures for many years although 
the refinements in techniques and equipment are of more recent origin. The 
present emphasis on training many geologists in photogrammetry is broadening 
their understanding of these techniques with an excellent effect. The most effec 
tive approach in introducing photogrammetric techniques for the first time is an 
introduction to the fundamentals of photogrammetry and a familiarization with 
the most widely used stereoplotting instruments; it is also important to convey 
a knowledge of their limitations. 
Several factors contributed to the adoption of these training programs for 
Survey geologists. One of these is, of course, the practical nature of photogram 
metry itself. The most compelling reasons, however, are the expanding require 
ments for geologic mapping in recent years and the need for more detailed 
mapping. In addition, it is believed that, as much of the national economy was 
dependent on the search for minerals and fuels, and we had on hand many new 
instruments and techniques brought about by research in recent years, these 
instruments could be applied to the task. There are also unique organizational 
advantages in the Geological Survey which facilitated this training program. 
As a means of expediting joint efforts towards more efficient utilization of 
photogrammetric techniques in geology, the Chief Topographic Engineer and 
the Chief Geologist formed, in 1953, an Interdivision Committee on Photogram- 
metric Techniques in Geology. As the work of the committee progressed, it 
became clear that training in the fundamentals of photogrammetry was one of 
the most pressing needs. It was decided to set up a ten-day training period in
