Using participatory geographic approaches for urban flood risk in Santiago de Chile: Insights from a governance analysis
Studies based on information acquired by participative geographic approaches have sought to cope with emergency situations and disasters such as floods. However, the impact of these approaches to flood risk governance systems in order to understand these types of events as a complete risk cycle is still not clear. In a recent paper, we analyse…

OpenFloodRiskMap Online combines Critical Infrastructure from OSM with Emergency Routing
some time ago we deployed OpenFloodRiskMap (OFRM) at http://ofrm.geog.uni-heidelberg.de/ OpenFloodRiskMap (OFRM) is a prototype web application to assist decision makers in developing alarm and operation plans for flood risk management. The OFRM hereby provides support in accessing critical infrastructure (CI) information in the OpenStreetMap (OSM) data base and to furthermore add this information to an…

Impressions from ISPRS Congress 2016 in Prague
As we mentioned earlier, we contributed four papers to the ISPRS congress and participated in the CATCON contest for brilliant Computer Assisted Teaching tools. Our new LiDAR Simulator called HELIOS developed by Sebastian Bechtold received a lot of attention. You can also find us in this video of congress day 3. Our young researchers Katharina,…

Local-scale flood mapping on vegetated floodplains from radiometrically calibrated airborne LiDAR dat
Knowledge about the magnitude of localised flooding of riverine areas is crucial for appropriate land management and administration at regional and local levels. However, detection and delineation of localised flooding with remote sensing techniques are often hampered on floodplains by the presence of herbaceous vegetation. To address this problem, our very recent paper presents the…

A Monitoring Tool for OpenStreetMap Mapathons in Python
In the last couple of weeks disastermappers Heidelberg and GIScience members were interested in finding a way to monitor changes in the OpenStreetMap database. This could help to provide better feedback after mapathons and could allow to measure how many objects like buildings or roads were created or modified during a mapathon. (It was even…

A review of volunteered geographic information quality assessment methods
While Volunteered Geographic Information (VGI) is gaining more and more popularity and VGI datasets are being used in various projects, there are always concerns about the quality of them. During the past years several studies have been performed regarding VGI quality assessment by employing different methods/approaches. However, if one needs to evaluate the quality of…
