| Zusammenfassung |
| Sea-level indicators (SLIs) represent archaeological/fossil samples or geomorphological
features with evidence of the relative sea-level (RSL) at the time of deposition or formation
with respect to today’s sea level. Usually, SLIs are analysed individually and the studies
extend over several decades. As a consequence, the results are spread in the literature
covering various disciplines, such as archaeology, ecology, glaciology and palaeontology. For
geophysical applications especially in the inference of glacial-isostatic adjustment (GIA), the
combination of different data as the extraction of process-related information is mandatory.
Therefore, compilations exist in review and research articles dealing with GIA, where
incomplete information on the individual SLIs is listed. Over the last decade, a database of
SLIs was built up at GFZ for the inference of the GIA process. Due to the often
heterogeneous information regarding the individual SLIs, the storage in a relational database
system was considered most suitable. This type of system enables the storage in individual
tables and, thus, allows to stay more close to the original representation of the data.
Furthermore, an individual or combined access and analysis of the data as the extraction of
process-related information is possible using an appropriate query language, such as SQL.
The second advantage is an easy connection to a graphical interface. In order to
analyse the data interactively, we decided in the project SLIVISU at GFZ for a
JAVA-based analysis tool and a visualization in Google Earth. We will show some
applications of the software and discuss further steps towards a web-based interface. |
