3. METHODOLOGICAL PROCEDURES. 
To evaluate spacial perception, some students newly-admitted to 
the Geography course were selected. The material here used were 
couples of panchromatic aerial photographies, scale 1:25.000,cove 
ring an area situated in the southern part of the metropolitan re 
rion.of Curitiba,.Brazil. 
The students serving as samples are listed below.

At first, some basic notions on photointerpretation, such as defi 
nition of photointerpretation, steps of photointerpretation, ele 
ments of recognition were offered as well as the procedures to ob 
tain the stereoscopic vision for photointerpretation. 
After that, each pupil received a pair of photos and,individually, 
placed them in stereoscopic so as to go with the photo-reading and 
photointerpretation in itself. 
4. DISCUSSION OF THE RESULTS. 
  
With this study, one can classify the identified elements into ca 
tegories and calculate its percentage. The most remarked aspects 
in the photos were: cultivation areas (35$); roads (23$); vegeta 
tion (26%). However, some invironmental clearly visible elements 
were not fully detected: projected forms (3%) and aspects of the 
drainage network (13%). The seats of the properties were not iden 
tified.
