| Zusammenfassung |
| This study is aimed to create an alternative to the classical GIS
representation of the impact of earthquake hazards on urban areas. To accomplish
this, the traditional map was revised, so that it can cope with contemporary innovative ways of planning, namely strategic planning. As in the theory of
fractals, the building dimension and the urban neighbourhood dimension are
addressed as different geographic scales between which lessons for decisions
can be learned through regression. The interaction between the two scales is
useful when looking for alternatives, for the completion of a GIS analysis,
and in choosing the landmarks, which, in the case of hazards, become
strategic elements in strategic planning. A methodology to innovate mapping
as a digital means for analysing and visualising the impact of hazards is
proposed. This method relies on concepts from various geography, urban
planning, structural engineering and architecture approaches related to
disaster management. The method has been tested at the building scale for
the N–S Boulevard in Bucharest, Romania, called Magheru. At the urban scale,
an incident database has been created, in which the case study for the
building level can be mapped. The paper presented is part of a larger
research work, which addresses decision making using the framework shown
here. The main value of the paper is in proposing a conceptual framework to
deconstruct the map for digital earthquake disaster impact analysis and
representation. The originality of the concept consists in the
representation of elements at different scales considered to be of different
levels of importance in the urban tissue, according to the analysis to be performed on them. |
