ABSTRACT
The rapid change of running modifications and processes simultaneously require and enable the execution of a
landscape monitoring. With latest methods and geo-information data an important contribution can be made in
particular to monitor and evaluate developments being carried out. The landscape monitoring dedicates itself to the
check and the prognosis of state and dynamics from natural to technical ecological systems.
In this project an analysis and an evaluation of the nature space potential for the suburban space are to be made by
means of remote sensing methods including geographical information systems (GIS). With the results derived a
progress control of desired planning goals can be made. Furthermore, planning deficiencies can be discovered, and
potentials for an influencing control can be shown to planning authorities of such cultural landscapes.
The project assesses the suitability of IRS-1C&D data for diverse planning requirements, e.g. updating land use plans,
municipal survey maps, maps of urban structure types and biotopes, surface-sealing surveys, and working maps for
landscape planning. It also examines the potential of IRS-1C&D data to provide the basis for updated general data
drawn to a scale of 1:25,000. This paper focuses on the use of IRS-1C data for automatic classification in urbanised
areas and on the application of a space reference model to analyse regional structures of certain classes with a stress on
gradients between an urban centre and its suburban surroundings. Later on, the project will test the application of very
high resolution data such as IKONOS data for certain test sites that are of special interest. First very high resolution data
are to be acquired and further research will then be undertaken.
1. INTRODUCTION
Since the reunification in 1990 the redevelopment process in east German urban regions has become a process which
has brought forward structurally modified and often disperse settlement structures in an extraordinarily short period of
time. This highly dynamic impact has led to a clear re-evaluation of the surrounding countryside and to an absolute
deconcentration of population and of work-places. Simultaneously, population density and employment figures show
far-reaching social, economic, and ecological consequences for the urban and peri-urban spaces.
The degree of an anthropogenic influence has reached its peak in urban landscapes. It increases in the suburban region
compared to almost natural and agricultural landscapes with the growth of overdevelopment. With respect to the
immensely expanding suburbanisation and settlement dispersion in German (and other European) urban-suburban
regions the importance moves from the centre to the suburbs of towns. This process is closely connected with an
enhancement of the suburban status and with an increasing deconcentration of population and working-places.
Suburbanisation processes should currently be observed by scientific investigations which have been lacking so far.
Such a monitoring could serve to analyse and evaluate the complex and widespread development processes in the
suburban area, and could characterize deriving models and recommendations for planning authorities. Such a recording
and description of spatial and dynamic processes needs the application of new quantitative methods and evaluation
approaches.
