Prototyp einer web-basierten Software-Anwendung zur Unterstützung des Water Safety Plan (WSP) Konzepts Gottwalt, Jonas; Riepl, David; Abecker, Andreas; Brauer, Friedericke; Fischer, Thilo; Sturm, Sebastian Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Reineke, Anja The Water Safety Plan (WSP) approach of the World Health Organization (WHO) is a com-prehensive framework for water-supply organizations (like water utilities, water authorities etc.) for systematically identifying and managing risks related to the drinking-water supply system. Up to now, there is not much and not very sophisticated ICT-support for WSP implementation. Hence, as part of the BMBF-funded research project TRUST, TZW and Disy together develop GIS-based tools for WSP realization. In this paper, we present a first prototype system for risk identification and risk assessment within the WSP framework.

Hochwassermanagement-Plattform für kleinere Städte und Kommunen mit Bürgerbeteiligung Burkhard, Simon; Fuchs-Kittowski, Frank; Müller, Ruben; Pfützner, Bernd Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Reineke, Anja In urban areas the damage potential by flood events is particularly high, regularly causing damages and economic losses. Early warning systems that can forecast such events with sufficient lead time are therefore very important. However, especially for small catchment areas the establishment and operation of forecasting systems is very difficult. On the one hand early warning systems have to deal with high spatial uncertainties of precipitation forecasts, on the other hand small catchments often show very fast reactions of the basin to heavy precipitation events. Moreover, in small catchments automatic gauging stations are often missing. This makes early flood forecasting complicated and very challenging. This paper presents a software platform for the flood management particularly for small river basins in German municipalities. It tries to solve the problems mentioned above via civic involvement by incorporating Volunteered Geographic Information (VGI). For this purpose, volunteers (citizens, municipal employees) are asked to acquire relevant hydrological and meteorological data via a smartphone application in order to compensate for the lack of official gauging stations. This includes e.g. water level measurements acquired via mobile image-based measurement methods. The information captured by volunteers is – in addition to open publicly available forecasting data provided by the German Meteorological Service Provider –automatically incorporated into the forecasting system in order to minimize forecasting uncertainties. A web-based dashboard available to crisis managers, e.g. disaster relief forces, visually processes and displays all relevant information and forecasting data thus enabling convenient monitoring of the situation (situation awareness).

Ein Namensdienst für die Küste Kohlus, Jörn; Krampf, Karina Fretag,Ulrike; Fuchs-Kittowski, Frank; Hosenfeld, Friedhelm; Abecker, Andreas; Reineke, Anja A Maps is the tool for orientation in unknown areas, for the orientation on maps text labels are needed. For the orientation on digital spatial data in coastal areas, a name service will be built up based on the German Coastal Gazetteer. A gazetteer is a multidimensional link-list of geographic names, geographic objects and their positions. The Coastal Gazetteer considers additional the contemporaneity. This data is stored in a PostGIS-database. For the name service it is filtered for a time validity. The results are transformed by Geoserver to an OGC-conform WMS. To design the labels YSLD (Styled Layer Descriptor described with YAML) is used. The properties of the geo-objects influence the presentation. The properties of the geo-objects are crucial for label styling. For the scale dependent display of the labels and the font size a priority of the object types is introduced.
