Sector 1, Bucharest, covers the geographical and historical
center of the city and the area towards the north of the city, on
both sides of the major axis north-south. It comprises areas of
the three main structural-functional zones: the central zone,
whose main function are the services and which has the aspect
of a modern metropolis; the intermediary zone, having mainly a
residential function and keeping aspects of the traditional town;
the peripheral zone, with multiple functions (residential, of
recreation, industrial etc.).

Figure 6. The urban environment quality from the first sector of
Bucharest drawn after analyzing IKONOS image
On the IKONOS image we can notice these three main zones,
differentiated from the point of view of the environment. Within
them there are smaller areas having different degrees of
ecological quality (Figure 6). This is how we have obtained the
thematic map representing the territorial variation of urban
environment quality in the sector under analysis.
S. CONCLUSIONS
Satellite images with spatial and spectral high resolution have a
large potential for obtaining detailed geometric data and for
realizing the land cover classification for the urban areas.
The analysis of the IKONOS image of the Bucharest (2001)
through corroborating several ecological criteria and several
parameters has allowed us to establish the environmental quality
categories and to map the corresponding areas.
By visual interpretation we have realized:
l. the image classification aimed to determine the land
cover classes based on the spectral properties of the
urban components (buildings, green and water areas);
2. the mapping and measuring of the green surfaces,
building density, of the pollution sources and affected
areas;
Following those steps we have defined four urban quality
classes and we have realized the thematic map of the sector 1 of
the Bucharest, which was our field application.
The outcome results can represent an information source for
updating the General Urban Development Plan of Bucharest.
