ABSTRACT 
The Universal Automatic Map Compilation Equipment 
(UNAMACE) is now being used by the U.S. Army Map 
Service to extract basic map data from a variety of 
aerial photography, including formats of up to 9 by 18 
inches. The equipment measures altitudes of up to 80 
digitally determined elemental areas per second with 
instrumental C-factors approaching 5000. Measured alti- 
tudes are output as drop-line charts, from which contours 
can be traced, and stored digitally on magnetic tape. 
Planimetric detail is shown on high-resolution ortho- 
photos prepared concurrently with the altitude measurement. 
The Automatic Photomapper is a compact version of the 
UNAMACE. It is van-mounted so that it can be moved 
easily to a theater of operations where it can be set up 
quickly for use. Operation with the Photomapper is limited 
to 9- by 9-inch format photography, or smaller, but other- 
wise it operates similarly to the UNAMACE. One of 
these units is currently being evaluated by the U.S. Army.
