Introduction 
Andrews Atherton, Inc. is a professional consulting firm located in 
Phoenix, Arizona, which offers services in Surveying, Civil Engineering, 
Analytical Photogrammetry and Archaeology. Services in analytical 
photogrammetry were initiated in the late spring of 1985 with the intent 
of specializing in close-range, terrestrial and low-altitude aerial 
projects in such diverse fields as engineering, industry, forensics, 
medicine and archaeology. Several projects have required innovation in 
control systems or specialized applications of photogrammetric and 
digital techniques. In addition, a unique computer network communica- 
tions system has been developed which allows the firm to provide disk, 
magnetic tape, modem or hardcopy output of digital data to clients in a 
variety of computer formats and languages. 
Close-range photogrammetric techniques provide efficient, cost-effective 
methods for solving measurement problems in a wide variety of fields, 
but only when practitioners in those fields are made aware of the capa- 
bilities of instrumentation and software. Innovative marketing tech- 
niques combined with the extraordinary potential of the AAI hardware/ 
software system provide a unique approach to sophisticated quantitative/ 
qualitative data collection, manipulation and analysis. 
Hardware 
The original AAI analytical photogrammetric system began with the in- 
stallation of a Kern DSR-11 stereorestitution instrument run by a DEC 
PDP-11/73 computer with a 42 megabyte Winchester hard disk drive and 
512 K-bytes of memory. A DEC LA 50 printer is used for hardcopy output 
and an HP7580-B graphic plotter produces finished ink-on-mylar drawinas 
in 24 inch by 36 inch format with up to eight pens. 
In February of 1986 this basic hardware system was upgraded by the 
addition of on-line and off-line Tektronix 4109 color araphics editing 
screens, a DIGI-DATA 1600 BPI magnetic tape drive, and an additional 
DEC VT-220 terminal for off-line computations. Figure ] illustrates the 
current system configuration. 
An AT&T 6300 computer has recently been added to provide a project plan- 
ning station in conjunction with specialized software from E. Coyote 
Enterprises, Inc. 
Software 
The original hardware configuration ran under the RT11 Operating System 
and utilized KERN MAPS 200 as a data collection program. Graphic output
