2.1 Integration into PHOCUS 
The integration of analog instruments into PHOCUS, 
the photogrammetric cartographic system from Carl 
Zeiss, is achieved by means of 
e the DIREC P counter and interface unit on a PC 
basis 
and the 
e A-software for absolute model orientation. 
This permits all data acquisition and editing 
functions of PHOCUS - insofar as they can be 
applied in analog instruments - to be used for 3D 
data acquisition. In line with the PHOCUS structure, 
the geometric data is collected with the correct 
topology and is stored together with the attribute 
data in an object-oriented form in the PHOCUS data 
base. The data acquisition process is supported by 
the PHOCUS panel, a programmable function 
keyboard. 
PHOCUS and the A-software run on a workstation 
platform: either on Silicon Graphics computers 
under UNIX or on DEC VAX or DEC AXP computers 
under VMS. The software can be implemented on its 
own computer to create a PA workstation, or it can 
be integrated as a PA workplace into the PHOCUS 
multi-user environment. The connection of analog 
instruments adds a further data source to the data 
acquisition options of PHOCUS, which comprise 
P-Series Planicomp analytical plotters, 
2D digitizers, 
PHODIS ST digitial stereplotter and 
monoplotting with the PHOCUS PM workstation. 
2.2 Plotting with CADMAP 
CADMAP is a photogrammetric CAD system from 
Carl Zeiss for digital mapping and GIS data 
acquisition, featuring particularly efficient acquisition 
and editing functions. CADMAP runs on the UNIX 
and MS-DOS platform. 
For the operation with UNIX, the DIREC P is again 
used as a counter and interface component for a 
Silicon Graphics workstation. When operated with 
MS-DOS, the PC is equipped with a special counter 
and interface PCB. Absolute orientation is 
performed by the ORIENT 3D program, and data 
acquisition is supported by a programmable function 
keyboard. 
The connection of analog instruments adds a further 
photogrammetric component to the data acquisition 
capabilities of CADMAP, which include 
P-Series Planicomp analytical plotters, 
2D digitizers and 
PHODIS ST digitial stereplotter.

2.3 Plotting with MicroStation and AutoCAD 
Carl Zeiss offers hardware and software packages 
for the integration of analog instruments into the 
MicroStation and AutoCAD CAD systems under 
MS-DOS. The package comprises: 
e Counter and interface modules integrated into the 
PC 
e ORIENT 3D program for absolute orientation and 
e CADMAP/dgn MicroStation driver for MicroStation 
5 or 
e CADMAP/dwg AutoCAD driver for AutoCAD 12 
e Function keyboard 
The driver permits the acquisition and processing of 
3D coordinates in a MicroStation or AutoCAD 
environment. The data is stored in the dgn or dwg 
format and output e.g. in the DXF format. 
The CAD working environment has been enhanced 
by special photogrammetric CADMAP functions 
which are not available in the CAD packages. This 
includes, for example, the digitization of lines using 
tube increments, the continuous display of 3D 
coordinates and the cutting, extension, bending and 
closing of lines. 
The commands are entered via standard and 
user-defined menues on the monitor or via a 
function keyboard. 
3. Upgrading of analytical plotters 
Analytical plotters comprising an opto-mechanical 
viewer, control and interface electronics, the host 
computer and the operating and plotting software 
allow the upgrading of each individual module to the 
latest standard. Upgrading is mainly centered on the 
electronics, the computer and software. 
3.1 Upgrading of C100 Planicomp to P2 Planicomp 
The C100 Planicomp launched by Carl Zeiss in 1976 
and supplied until 1987 is operated by the HP 1000 
real-time computers, while the LOOP real-time 
computation and control are handled by the host 
computer. 
With the introduction of the P-Series Planicomp (P1, 
P2, P3 Planicomp), a microprocessor (P-processor) 
integrated into the instrument electronics is used for 
real-time computation. The P2 Planicomp is based 
on the time-tested viewer of the C100 equipped with 
the P-processor and a standard interface (RS232, 
IEEE-488) with the host computer.
