VIL Your suggestions, comments relevant to the photogrammetric 
operations (conventional, none onventional) will be appreciated. 
It is desired to compile the responses from the members of this W.G., 
based on which our next line of action will be chalked out. 
***** 
The response was not total. Only eight (out of a possible twenty) answers 
were received during the last year. However, ¿hese are somewhat 
representative, being from eight different countries with diverse politico- 
economic backgrounds. 
The following general conclusions are drawn from these (the numbers 
refer to the corresponding questions): 
L 1. Some kind of cost-model is used, at least in calculating the total 
cost of specific projects. 
The economic fluctuations of the country is generally 
considered. This is done, in some cases, somewhat 
indirectly, e.g., in terms of cost of labor fluctuations, 
depreciation of equipment, administrative overhead, etc.

Amongst the cost factors, (a) the ''Level of Use" considera 
tion is done only in terms of generalizing or rounding of 
cost figures. 
(b) Inheritance is of great 
significance. The techniques appear to be greatly biased 
on available equipment, trained personnel. Even socio 
political influences like Foreign Exchange limitations have 
great impacts as one of the cost factors in some countries. 
(c) Research and Development 
are considered primarily to adopt accepted methods to local 
(d) Amongst the input items, 
generally "Materials and Equipment" is considered with 
high emphasis, "Capital" with somewhat lower emphasis 
(one member indicating no). On the other hand, "Labor" 
is generally considered with low emphasis (one member 
indicated no to this item). 
(e) On the output items, one 
member indicated no to all items. In general, however, 
digital information is considered only for- aerial triangula 
tion data or cadastral work and publications are generally 
confined to short reports on the projects.
