The map shows the
maximum soil moisture index within the selected time window.
The data set describes the soil moisture
index (SMI) observed in Germany in the time range from 1990 to
2019. This index is an indicator for droughts. In contrast to the
other data sets it is given as raster data, which have translated
into point data by considering the centers of the cells. With this
we obtained over 8 millions events each annotated with the
SMI. Despite its rasterized appearance we consider this data set in
our experiments as it is large and each event has an additional
weight. Hence, it is a suitable benchmark set for the evaluation
of the delta-structure.
The data has been obtained from
UFZ-Dürremonitor/ Helmholtz-Zentrum für Umweltforschung.
We do not assume any warranty and liability for the accuracy of the data, but the only purpose of this map is to showcase the developed data structure and its applicability.
