De Waal Archifoto Ltd., on the other hand, has concentrated its effort on the use of Zeiss and Wild 
stereo-cameras for special applications, such as: 
a. Measurements of buildings and archaeological objects 
b. Measurements of the movement of buildings. 
CHAPTER VI. EDUCATION 
The result of a growing interest in the use of information that can be gleaned from aerial photo- 
graphs, has led to an increase in the number of courses in photo interpretation and remote sensing 
which have been started in some faculties and to an increase in the amount of time and the number of 
students of existing courses. 
This trend is noticeable at both university and non-university level Short courses and developments 
were started in the Engineering Department of the Technological University at Delft and at the 
Agricultural University Wageningen. An interdepartmental course in Rural Surveys has also been 
established at ITC. 
An increasing emphasis is being placed in courses dealing with newer remote sensing techniques such 
as radar, multi-spectral scanning, etc. and on data-recording from orbital altitudes. 
The ITC, having probably the only self-contained and complete course in aerial photography in the 
world, has improved their courses in "Survey Flight" and "Aerial Photographic Technology". Their 
equipment now includes a Piper Navajo Chieftain PA—31 aircraft equipped for various functions (a 
flying classroom), a survey flight trainer-simulator, fully equipped airconditioned laboratories, and 
production and control instruments. 
Between 1972—1976 two new periodicals the ITC Journal (4 x year) and the ,,Cartographisch Tijd- 
schrift" (4 x year) have been published. 
History 
The board of the Dutch society for Photogrammetry is considering the suggestion of installing a 
"photogrammetric museum" in which many of the old instruments, now in cellars, can be housed. 
Bibliography 
The edition of the ITC International Bibliography of Photogrammetry and Photo-interpretation 
continued regularly. 
CHAPTER VII. PHOTO INTERPRETATION 
Netherlands Interdepartmental Working party for Applied research of Remote Sensing (NIWARS), a 
working group set up in 1970 with funds made available by the Netherlands Government, has greatly 
stimulated and to a large extent coordinated the research in the field of remote sensing. There are 17 
scientific and technical personnel in this group who cooperate with many governmental institutions 
and universities including ITC and the Department of Public Works. Most of the research projects, 
deal with multi-spectral scanning and thermographic recording and are carried out by sub-groups for 
vegetation, geology, soil science, hydrology and for public works. The activities of NIWARS will 
terminate early in 1977 but several of the projects initiated by them will be continued individually by 
the participating organisations.
