Figure 5 SCALES 
The result is a normal distribution over the different classes, 
whereby scales in de region of 1 : 50000 are the most populare It can 
also be discerned from this table that the various scales reveal a relation- 
ship with the size of the administrative areas. In this respect, the 
national level is an exception; there is more agreement with the distribu- 
tion at the local level. This is due to a certain type of usage such as 
control of execution of projects and specific use in urban areas (urban 
renewal, care for moruments, etc. ). 
To obtain an impression of the frequency with which photographs are 
taken, all users were asked when they started ihe most recent project. The 
results are recorded in figure 6.
