High resolution analog or 1024 X 1024 digital images can be displayed 
on the two monitors. One monitor is a color monitor where we can 
display images in either monochrome or through the three color channels. 
The other monitor is a black and white monitor where we can display 
only monochrome. Both monitors can be used to display the realtime 
analog video from any camera or a digital image from either the color 
or monochrome memory. Autotracking software allows the analyst to 
create master and slave stations. The data tablet cursor is used 
to scroll on the master station. The slave station moves to keep 
the same geographic coordinates centered on both monitors. This 
capability can ‘be used to track a feature such as a road, river or 
power line. 
These are some of the abilities of the SAS as listed by the contractor 
in their Final Design Plan: 
- Video softcopy display of hardcopy images/graphics. 
- Firmware warping of one image to another. 
- Video digitization of analog display into 1024 X 1024 
state-of-the-art pixel representation. 
- Multiple viewing modes 
side by side 
split screen 
superimposition fade 
superimposition flicker 
- Display enhancements 
gray scale manipulation 
zoom & scroll 
pseudocolor enhancement 
- Interactive graphic tools for pointing and tracing 
- Text data entry functions 
- User console for centralized remote control of input stations 
Output from the SAS can be in many forms. Formatted reports that 
list hazards to navigation can be printed for inclusion in current 
publications. Session listings for analysts records can also be printed 
out as well as source code for programmers.
