In order to carry out this pro 
   
  
indispensable that the member s 
of its value and usefulness, and also that they should be willing to take 
part and meet their engagements in this common work. 
The final aim of the project shall be to describe the HISTORY OF PHOTOGRAM- 
METRY and the DEVELOPMENT OF PHOTOGRAMMETRIC METHODS AND INSTRUMENTS in all 
countries, societies or institutions of which are members of ISP, It is un-- 
derstood that "Photogrammetry" includes here also the "Photointerpretation”. 
2. CONTENTS AND SUBDIVISION 
The project should content 
= national as well as international application and development of photogram- 
metry and its application in various countries,chronologically till 1970. 
- technical development of photogrammetric methods and instruments in va - 
rious countries from the past up to tbe present; here it is necessary to 
describe excludingly those methods, procedures and instruments having been c o 
developed in a certain country, particularly those ones, which were influ- 
encing further development of photogrammetry. 
The final HISTORY OF PHOTOGRAMMETRY will also contain the development of pho- 
togrammetric methods and instruments in various periods of time.A systematic 
and detailed pursuit of development e.g. of special technical methods and 
instruments from the beginning till the present day will often be very dif- 
ficult. The latter mentioned possibility would be of great importance for an 
active photogrammeter user, especially if this information is "up to date", 
As the historic presentation in this sense becomes rapidly out of date, it 
is suggested that the DEVELOPMENT OF PHOTOGRAMMETRIC METHODS AND INSTRUMENTS 
will be published in the form of Card-register-type papers. 
It is thus considered to dívide the present project into two parts: 
HISTORY OF PHOTOGRAMMETRY 
- DEVELOPMENT OF PHOTOGRAMMETRIC METHODS AND INSTRUMENTS 
2.1 HISTORY OF PHOTOGRAMMETRY 
The basic material of this part will consist of the relatively brief and 
complete historical national reports of the single member countries in one e © 
of three ISP official languages. The information in a uniform and con -
