2. UNIVERSAL PHOTOGRAMMETRIC/CARTOGRAPHIC DATA PROCESSING WITH 
PHOCUS 
Carl Zeiss has gained experience in the design and marketing of photogram- 
metric instruments for decades. The development of modular application 
programs that led right up to the PLANIMAP digital mapping system began 
when the C 100 Planicomp analytical plotter was introduced at the 
13th ISP Congress at Helsinki in 1976. 
A milestone in this development came in 1987, when the data-base-oriented 
PHOCUS photogrammetric and cartographic information system was introduced 
together with the P-Series Planicomp, the second generation of analytical 
plotters. 
The PHOCUS software product fully satisfies the demands listed in Fig. 1. 
The fields of application listed in Fig. 2 illustrate the current range of 
functions.

Fig. 2: Major Current PHOCUS Applications 
PHOCUS is based on the structured management of geometric and non-geo- 
metric data in a data base (DB). The PHOCUS software structure is 
characterized by the fact that all functions are activated and controlled 
by the integrated PHOCUS operating system. 
The software system can be used on HP 1000 A Series and DEC MicroVAX work- 
station computers. PHOCUS supports the following general hardware environ-
