Abstract: Urban flooding has been increasing in recent years and therefore new specified methods need to be developed and applied. The rise of Web 2.0 technologies and collaborative projects based on volunteered geographic information like OpenStreetMap (OSM) lead to new dimensions of participatory practices. Thus, citizens can provide local knowledge for natural hazard analysis in a convenient way. In the following, a case study of the Quilicura community in Santiago de Chile -regularly affected by urban floods- is presented. A combination of OSM Field Papers and the risk perception of local people is applied in the concept of risk awareness maps including a questionnaire for participants? information. This explorative study is a promising approach for a complementing data source because insight into local knowledge is acquired in a fast way. Results reveal two main streets, which are identified by the participants as prone to urban floods.

Abstract: “Over the last couple of years, the growing OpenStreetMap (OSM) data base repeatedly proved its potential for various use cases, including disaster management. Disaster mapping activations show increasing contributions, but oftentimes raise questions related to the quality of the provided \emph{Volunteered Geographic Information} (VGI). In order to better monitor and understand OSM mapping and data quality, we developed a software platform that applies big data technology to OSM full history data. OSM full history data monitoring allows detailed analyses of the OSM data evolution and the detection of remarkable patterns over time. This paper illustrates the specific potential of the platform for disaster activations by means of two case studies. Initial results demonstrate that our flexible and scalable platform structure enables fast and easy information extraction and supports mapping processes and data quality assurance.”
