5. VIDEOMAP and PLANITAB 
  
Leaving aside the generally available Planicomp periphery, the VIDEOMAP 
and PLANITAB photogrammetric output devices are discussed in more detail 
below. 
VIDEOMAP 
Zeiss VIDEOMAP consists of a special graphics and display processor and 
an HP vector refresh monitor. Superimposing graphical information on the 
air photo in the analytical stereoplotter offers not only the above-men- 
tioned advantage of real-time digital map checking. Apart from measured 
data logging, significant future VIDEOMAP applications will include super- 
imposition of invisible information such as properly lines or utility 
networks for comparison and proper inclusion in the PLANIMAP file; super- 
imposition of existing maps (digitized with DIGI-AS, if applicable) for 
map revision; or superimposition of plans or models for comparison with 
the "real world" of a current stereo model. 
Together with the Planicomp, the following applications are already being 
supported by VIDEOMAP (in addition to digital mapping): 
- Representation of single-point measurements for orientation, aerotrian- 
gulation and cadastral work (the C 123 program now supports VIDEOMAP). 
- Representation of progressively sampled points and lines 
(PROSA output to VIDEOMAP), 
- Representation and verification of HIFI results with VIDEOMAP 
(in preparation). 
To conclude, the VIDEOMAP software interface is documented and a subrou- 
tine library for HP 1000 computers is available so that users can program 
their own applications. 
PLANITAB 
The T 110 and T 102 PLANITAB Tracing Tables are identical in concept, 
technology and accessories and feature high precision, speed and accele- 
ration. Compared to the low-cost T 110 PLANITAB the T 102 offers a larger 
size, higher acceleration and higher operator convenience. The tracing 
tables and the tracing heads are prepared for single and quadruple tan- 
gential conrol. The tracing surface can be illuminated and equipped with 
a vacuum system for optimum paper flattening. It can be tilted and, in 
the T 102, height-adjusted. To orient map sheets and digitize individual 
points, a setting microscope and a TV system consisting of a camera and 
a monitor are available. 
The processor which controls these tracing tables can be programmed by 
means of a comprehensive set of commands. The GRAPH F2 subroutine library 
is available for HP 1000 computers. GRAPH F2 and mapping programs together 
form the PLTAB-AS software package for graphical output on separate T 110 
and T 102 tables connected to an HP 1000.
