Introduction 
   
In the Congress Programme the task of the Intercommission Working Group IV — VII 
is described as follows: 
"Integration of Photogrammetric mapping and photo-interpretation for natural re- 
sources inventory for countries in development". 
The activities of this young working group have so far been very limited. 
The chairman invited the representative of the International Institute for Aerial 
Survey and Earth Sciences in the working group to deliver a paper, more or less as 
a starting point for a discussion. A discussion which could have as theme: "The 
role of resources development photogrammetry in the integrated activities in the 
developing countries - & problem of optimation of quality versus quantity — 
and of the inter-relationship of the mapping and inventory phases of surveys". 
These are the words of the chairman of the working group. 
The word "optimation'" was used here. This may be considered the ultimate aim of 
the activities of the working group. We are still far from this ultimate aim, 
ard have to look for starting points. 
Which products can be delivered by the map maker, or, practically, by the photo- 
grammetrist ? 
These are aerial photographs (different scales, different emulsions), mosaics, 
Sketch-maps, orthophotographs and topographic maps, more or less complete, in 
manuscript form or printed. 
Integrated Res. Surveys 
In recent years more and more attention has been paid to the team work of re- 
sources surveyors, and the expression "Integrated Surveys" is often heard. 
We quote a definition by Vink (1967): "Integrated Survey is the co-ordinatedpre- 
paration, execution cand evaluation of topographic surveys, natural resources sur- 
veys and human resources surveys in such a way that a comprehensive picture in 
the form of maps with reports is obtained", 
In this definition we see that the topographic surveyor is considered to be a 
full member of the team. In addition to this the maps are mentioned before the 
reports. We feel it is essential for the topographic surveyor to be in the team 
and to contribute, advise and help the other specialists in every phase of their 
work. We consider his task to be subordinate to the others. To make a map is never 
a goal in itself. To find rules for co-operation between the map-maker and the 
cther specialists is one of the aims of the Intercommission Working Group IV/VII. 
Another definition, by Mohrmann (1968), is: "Integrated Survey is a survey of a 
comprehensive character in which different scientific discinlines are involved, 
forming in their forced coherence together a greater scientific unit, in which 
the participating disciplines have a subordinate position, but without losing 
their proper nature," 
The word "subordinate" in this definition, we understand, means "subordinate to 
the final aim of the survey: development".
