Disk file storage includes initialization, and registration of charts, 
Annotation data is also kept by the analysts on their personal disks. 
For those who wish to know system commands and the text editor, many 
other files can be kept on personal disks. 
Annotations can be plotted on a registered chart or overlay. This 
is not limited by scale. For instance, annotations digitized from 
film of one scale can be plotted on several charts of different scale. 
Video output can be the analog video picture actively being seen 
by the camera. The analog image can be made into a digital image 
stored in digital memory and/or displayed on the monitor. These digital 
images can further be manipulated with B/W or color enhancement 
software, zoom and scroll operations, and the high speed hardware 
warping function. 
CRT outputs include geographic coordinates as a response to 
interactive query on registered charts and responses to standard 
operating system commands. 
The system hardware, configuration is shown in the attached diagram. 
Single and double headed arrows show where the communication is 1 
way or 2 way. The dotted line represents the workstation configuration. 
In summary, the Source Assessment System is a unique collection 
of state-of-the-art hardware and custom software. It provides an 
analyst the ability to do accurate source assessment with ease and 
efficiency.
