In monuments with repeated structures, the correlation method was used. It was recognized 
  
by correlation in the first execution of the program in 6 points over 8. 
Used aerial photographs were taken with a Carl Zeis RMK AT 15/23 camera, 153mm focal 
distance. Using a window of 10 x 10 pixels as exploration kernel, the automatic recognition 
was tested by digital correlation for crossings of roads features. They were identified in the 
first execution 8 of the 12 crossings and other points with same statistical characteristics. 
Graphical results are shown in poster session. 
6 CONSIDERATIONS 
Adequate election of marks was fundamental to reach with success the recognition 
objectives. They were contemplated three fundamental aspects: form, size and mark 
contrast. Circles on square mark are appropriate when the image has form heterogeneity. 
Results obtained in the digital correlation through the elaborated program were reached 
without inconveniences with a personal computer. 
Obtained results in FAD, independently of basics photogrammetry analyzed topics, served as 
educational tool for photogrammetry disciplines inclusion in graduation and post-graduation 
courses in two South America universities: Universidad Federal de Santa Catarina, Brazil 
and Universidad Nacional del Litoral, Argentina.
