The Advanced ^utomatie Compilation System (^'C83) is being developed
as a follow-on to the Universal ^utomatic Vap Compilation Fquipment
(UNAMACE). Starting with a stereopair of photographs, the system
utilizes an all-electronic scanning system. The output consists of
contours, black-and-white or color orthnophotogcraphs and digital
terrain information (Mayer, 1974; Madison, 19753;
A system for Replacement of Photographie Imagery Fquipment (RPIF)
is used to replace the imagery on a relatively low-resolution ortho-
photo by high resolution imagery from panoramic photographs. The
RPIF can also be used for change detection and updating existing
photography.
The Automatic Reseau Measuring Fquipment (ARMF)is designed for rapid
and accurate measuring of stars, reseaus, and marked poînts on
photographs. It will be used primarily for the calibration and
quality control of reseau cameras (Roos, 1975).
The Semiautomatic Cartography System (SACARTS), now in operation,
employs UNAMACE-produced orthophotography and elevation data, which
are edited by means of interactive cathode-ray-tube (CRT) devices.
Magnetic tapes are developed and used to produce graphics on either
flatbed or raster plotters. SACARTS produces symbolized color
separations for map production, while the digital data are used for
terrain analysis (Junkins and Jancaitis, 1974).
A system of Automatic Terrain Fnhancement (ATE) is being developed
to automatically produce shaded relief, elevation tints, and per-
spective views from digital elevation data.
The Analytical Photogrammetric Positioning System (APPS) uses a simple
stereometer and minicomputer to determine the horizontal coordinates
and elevation of selected ground points. The input consists of photo-
graphs which have been premarked and triangulated.
The Natural Image Computer (NIC) was designed as a pattern-recognition
tool for automating the process of recognizing and delineating map
detail or geographic intelligence. On the basis of NIC, the Automated
Image Data Fxtraction System (AIDES) was developed (Murphy, 1974).
The Digital Ortho Rectification of Planimetry Systems (DREPS) provides
for digitizing directly from unrectified aerial photographs so that
planimetric features may be compiled without sacrificing accuracy.
This system permits the traditionally sequential operations of analytical
triangulation and compilation to be carried out in parallel thus shorteni
the total through-put time.
