CONCLUDING REMARKS 
In this paper a general orientation theory of two- 
dimensional affine imageries has been derived for 
the ultra-precise three-dimensional measurement 
by a conventional comparator and for the analysis 
of satellite CCD camera imageries having a very 
narrow field angle and very small height differ- 
ences in the photographed terrains. Also, a general 
free network theory for affine imageries has been 
constructed. Tests with simulated examples clari- 
fied that the proposed theories were mathematical- 
ly sound and useful for the analysis of two-dimen- 
sional affine imageries.
