(c) Post-graduates: They are very few and function in the immediately 
lower level, i.e. that of the production engineer. They are normally 
under senior self-trained professionals, due to the time-of-service 
dominated epetiris, or the owner of a private firm. At best they func 
tion as ad\ isors of the higher level. The lack of competent post 
graduates at proper posts is filled by university staff members, who 
are invited to act as consultants. 
The above described situation is strongly related to the hellenic 
education system, which is described in the following paragraph. 
5. THE HELLENIC EDUCATION SYSTEM IN RESPECT TO PHOTOGRAMMETRY 
AND REMOTE SENSING 
There is nothing like a formal course of study to produce quali 
fied technicians. Although the Technological Institutes are comparatively 
well equipped in photogrammetric instruments, their graduates ’’Surveyors" 
are oriented to land surveying applications. As stated above, operators are 
being trained by the individual public sector organizations. 
Photogrammetric needs are rather limited in this country to jus 
tify the existence of a university level course leading to a degree in pho 
togrammetric engineering. The most explicit courses are belonging to the 
curricula of the Schools of Rural and Surveying Engineering (Technical 
Universities of Athens and Thessaloniki). Graduated Rural and Surveying 
Engineers are "passive" photogrammetrists, having the potential to become 
"active" (Fig. 5.1) ("active" and "passive" in the context given by Adamec 
and Ellis (1980) and Adamec( 1984)). 
Photogrammetric courses offered to undergraduate Rural and Sur 
veying Engineers contain some 80 hours of theory and 80-110 hours of 
practice for the whole of their study, distributed in three semesters 
(Rokos, 1984). Students have the opportunity to work on instruments some 
10-20 hours per year in average. This figure is reduced if they do not 
take the third course, which is for both universities selective. Compared to 
the corresponding figures given for European Universities, which also pro 
duce "passive" photogrammetrists (Erez, 1980) the amount of instruction 
time is at the lowest margin, while the offered subjects are more (f.e. 
orthophotography, aerial triangulation and non-conventional photogram— 
metry).
