In Figure 4 the populations grow and the in-crease of residential 
area have been compared. Interesting is the extreme grow 
between 68 and 88 of the residential surface. In detailed studies 
can be seen, that a big amount was in less dense residential 
areas, might be legalised Gecekondu. After 1988 the situation 
changes. Both lines still have a strong increase, but the 
residential surface slows down meanwhile the population rate 
| & increases. This affects a higher population density. More big 
buildings with bigger density have been built. These types of 
residences grow strong, similar to the population. By 
interpretation of the CHANGE Data, key-areas of specific 
change can be detected and analysed. Such areas have a role for 
the development of the entire city and they are result of some

ite related to political keys, such as law-restrictions. Especially in 
Ram Istanbul some events (road-construction) initiated the increase

The difference in the increase of the transportation network 
md shows the stronger development of the Asiatic side. The main 
initiation was the bride-construction in the year 1972 and 1987. 
Also when the bridge was not ready, the development already 
use. had started.

Figure 6 visualises the grow of artificial fabric. While the grow 
on the European side is concentrated around the central part of 
Istanbul, the increase on the Asiatic side is fixed along the coast 
of the Marmara Sea. 
Based on the undertaken studies 
and the natural limits, axes of 
further grow of urban fabric can 
be estimated. This is shown in 
figure 8. The forest gives a 
limitation to the north. The 
length of the arrows indicates the 
intensity of increase. 
Scenarios out of trend-analyses 
can be undertaken and a virtual 
grow of the city can be animated. 
Such scenario visualise the 
problems of the city, where 
increase is dramatically big. The 
project-data could be a suitable 
base for emergency planning. 
The output can be used in a large 
variety of applications, not only
