the capability of conducting interior, relative and absolute 
orientation very much faster by semiautomatic procedures 
the setting of a point by previously recorded ground-, model-, 
or photo coordinates 
the use of the plotting table as automatic coordinatograph 
with all plotting software consequences (points, lines, 
symbols, curves) 
the storage of elevation sequences of grids, in profiles or 
of coded points and lines for the generation of DM's or for 
use in automatic cartography. 
The utilization of these capabilities for photogrammetric tasks 
will only be useful if the system of the photogrammetric processes 
starting from data collection via data input to end product 
(point coordinates, DIM, map, orthophoto) is considered. To im- 
prove the ease, reliability, speed or accuracy of the operation 
process by an analytical plotter special task oriented programs 
must be available. 
To generate such task oriented programs two prerequisites must 
be fulfilled: 
1. the operational capabilities and thelr steps must be pro- 
grammed in modules 
Figure 5 
such modules should be small enough for documentation on one 
page in form of a Structogram used in "structured programming" 
Figure 6 
In this type of programming certain rules must be observed, 
whether the programming is done in compiler (orientation 
routines) or in assembler (usually real time operation) 
(no Go To's may be used) 
the modules must be fitted together for a certain task. 
For this type of task-programming 3 applications have been 
made at the T.U. Hannover: 
a) the use of the A.P. as terrestrial plotter; 
the orientation elements are computed via input conditions 
of directed lines, fixed angles, fixed parallel distances 
b) the use of the A.P. as aerial triangulator with semi- 
automatic point transfer 
c) the use of the A.P. as a digital data acquisition device. 
Mr. Keune and Mr. Riidenauer will now report briefly about the 
latter two projects.
