superior data base system. If stand-alone workstation and the 
data base system do not belong to one network compound, the 
time spent on transferring of graphical data can be very 
lengthy. 
4. Presentation of Data 
A 
The final product of the digital graphic data stored in the 
land information system will be an analog presentation in form 
of a map for many users. The analog output of these data can 
be performed on simple hard-copy instruments, fast drum plot- 
ters or high precision flatbed plotting tables, depending on 
the required accuracy, therequired number of copies and the 
task. Scale, contents and the way of presentation should be 
variable up to this step of performance. For the application 
of printed maps different overlays are engraved, one for each 
printing ink. 
As a clear scaled presentation with a high information density 
and special graphic detail information an orthophotomap can 
be produced. An orthophotomap is the combination of an ortho- 
photo with a linemap. For the production of the orthophoto the 
land information system data are also useful because of their 
hight information. An orthophotomap can be a helpful instrument 
for planning activities./STAMPA-WESSEL; ENGEL 86/

Some data of a land information system can be useful for 
additional purposes if they are transferred into a digital 
image processing system. On the one hand they can deliver 
passpoint information for the geometrical rectification 
of remote sensing data, on the other hand they can be included 
into classification algorithms as à priori acknowledgement. 
The combination of geometrical and additional information of 
a land information system and multispectral images let expect 
good results for purposes like the production of maps for 
landuse or geological activities. 
To find an optimal way for the processing of those two data- 
types and the combination of land information systems with 
digital image data-bases some more research has to be done.
