SECTION I. GENERAL DISCUSSION 
SCOPE. 
This paper, entitled 'Automatic, Analytic, and Allied Photogrammetric 
Equipment, " is to be considered as a supplement to the one entitled ’Analog 
Photogrammetric Equipment" as well as the one entitled "Automation in Photo 
interpretation. " Its purpose is to indicate the progress made in the last four 
years; to call attention to newly developed equipment; to discuss the trends 
evolving in the fields of automatic, analytic, and allied photogrammetric equip 
ment; and to set the stage for discussions by experts regarding this matter. 
DEFINITIONS. 
Automation as used herein is the automatically controlled operation of a 
system, process, or apparatus by devices (mechanical or electronic) that re 
place the human organs of effort, observation, and/or decisions. Automatic or 
semi-automatic equipment to be covered are those which utilize complete or 
partial automation of their basic photogrammetric function. Included are those 
classified as monoscopic and stereoscopic comparators; those having aerial 
triangulation and/or compilation capabilities; and those of a universal nature 
having aerial triangulation, compilation, and/or orthophoto capabilities with 
possible additional capabilities of drop-line (point) profiling and/or digital co 
ordinate point recording. 
Analytic equipment as used herein include those that have characteristics 
similar to the photogrammetric equipment referred to above, but which are 
"computer-aided. " Under such circumstances a computer may be utilized as a 
separate entity; a computer may be interfaced (that is, used "on-line") with 
the photogrammetric equipment; or a computer may be utilized on a remote 
access ("time-sharing") basis. 
Analog equipment as used herein include those which utilize mechanical 
and/or optical trains to carry out basic photogrammetric functions of projection, 
observing of images (or model), and measuring of coordinates (or plotting of the 
model). Not included in this category are those that incorporate partial or com 
plete automation of the observation process, as well as those that incorporate 
the automation of the recording and processing of data derived from photogram 
metric observations. 
Allied equipment as used herein include those related by common prop 
erties or similar characteristics. Included are automatic point-pricking 
devices, image enhancers, automatic coordinate readers or recorders, image 
correlation devices, and other auxiliary instruments.
