Among the more recent other analytical plotter s are: 
1. The Goodyear Radar Rest itutor 
built for USETL with the features of a general analytical 
plotter, except that it has been built for restitution of 
radar images. 
2. The Bendix Research Facility 
which makes minimal use of a panel, but utilizes a CRT 
input device controlled by a typewriter, and which is unique 
in that it can encode as a record both model and photo 
coordinates /14/. 
3. The automatic comparators TA 3/PA and the latest version 
TA 3/P 1 of Bendix which can be considered as complete analytical 
plotters without a plotting table /15/. 
4. The Galileo D.S. Digital Stereocartograph 
of Prof, Inghilleri which is unique in that it encodes 3 
image coordinates (x f , y' and Ax"), calculates model coordinates 
x, y, z and therefore only requires one image servo (Ay") as 
opposed to four on the standard analytical plotter (x' y' x" y") 
in addition to the plotting table servos (x T y T ) /16/.

3. AP/C Analytical Plotter Software 
While many of the analytical plotters in existence show very 
interesting aspects a discussion of the software aspects should 
be limited 
a) to the most frequently used 
b) to the most accessible 
c) to the most innovative,general 
systems:
