9. Pattern-recognition systems for automatic 
image-data extraction have been developed to 
the practical stage. 
10. Optical techniques, such as fiber optics, 
coherent optical correlation, and optical spec- 
trum analysis, provide a potentially valuable 
alternative means of automating photogramme- 
tric processes. 
11. Remote sensing records other than pho- 
tographic imagery can be expected to play an 
increasing role as input material for automated 
photogrammetry. 
12. Materials obtained from LANDSAT, 
Skylab, and other space vehicles have a poten- 
tial for automated production of small-scale 
maps. 
13. Automated electronic techniques afford 
important economies in photolab operation. 
14. Automated photogrammetry has many 
specific applications in terrain-related enginee- 
ring problems. 
15. The mapping system of the future can 
be envisioned as a completely automated carto- 
graphic system in which the entire map is built 
by digital and nondigital automatic processes, 
with the photogrammetric phase constituting 
one element of a comprehensive system. 
It is safe to say that of all the automation de- 
velopments that have been mentioned, not one 
has reached the ultimate stage of economy, 
technology, or quality of output (Thompson, 
1974). Advances and improvements will conti- 
nue, and the state of the art presented here, 
describing the most modern and sophisticated 
developments, will doubtless be obsolete at the 
time of the next International Congress in 
1980. We can regard the state of progress with 
satisfaction, for the photogrammetric profession 
is composed of tireless people who will never 
stop working to advance the state of the art.
