Figure 2 RESPONSE 
In this table, two points are significant: 
— the low response from the non-government organisations: in all proba- 
bility, the non-respondents can be considered to be non-users 
— the small number of respondents at the provincial level who can be 
considered to be users: this is mainly a result of the fact that one 
of the three bodies at provincial level (housing) combines a high 
response (9 at of 11) with a totally negative response with regard to use 
of aerial photographs (9 out of 9). This could suggest a mistaken impres- 
sion of the activities of this institution. (The figures would have been 
for the provincial level 22, 14 and 8 respectively. ) 
The obvious hypothesis that the conventional black and white 
photograph is the most frequently used material is indeed supported by 
the results of the questionnaire as recorded in figure 3.
