GIS Colloquium – Talks (Winter Term 2018/2019)
3D Model and Geovisualization for monitoring and prediction of landslides in Brazil - The RedeGeo Project (Cemaden and UNESP Collaboration)
Prof. Dr. Silvio Jorge Coelho Simoes
Mon, January 14, 2.15 pm (Venue: INF 348, Room 015)
Landslides have a high degree of uncertainty requiring new methods for their analysis, monitoring and forecasting. In Brazil, Cemaden (Brazilian Center for Early Warning and Monitoring for Natural Disasters) is responsible for actions related to natural disasters. Recently, a collaboration with Sao Paulo State University (UNESP) was started to study landslide-prone areas situated in different regions of the country. This talk presents the proposal of implanting a laboratory of modeling and geovisualization to improve the processes of analysis, monitoring and prediction of landslide phenomena that occur mainly in areas unsuited to habitation due to the geologic and geomorphologic conditions. The laboratory consists of three parts: A) Field surveys to obtain high resolution images from unmanned aerial vehicles and to obtain the internal geometry of outcrops from geophysics methods; B) 3D modeling allowing the analysis of multivariate data such as superficial and sub-superficial geologic maps, boreholes, cross sections and geophysical data considering their volumetric properties; C) Geovisualization and Virtual Reality (VR) where the images obtained in the fieldwork can be observed from a human-machine interface which allows that the researchers have a full immersion in the selected areas. The creation of this laboratory related to the natural disasters including geovisualization and VR stimulates the active participation of the researcher team, and creates mechanisms for the participation of technologies developers, managers, civil defense agents and even the population that lives in the risk-prone areas.
Supporting the most vulnerable people before the disaster strikes – International Disaster Risk Reduction within the German Red Cross

The German Red Cross (GRC) is part of the worldwide Red Cross and Red Crescent Movement with its presently 191 recognized National Red Cross or Red Crescent Societies. A major focus of the GRC's international cooperation is on supporting the most vulnerable people around the world in addressing the impacts of natural hazards like tsunamis or floods. The presentation is going to give insights into approaches and activities in the area of Disaster Risk Reduction. Nevertheless it is also supposed to trigger a dialogue about how humanitarian organizations like GRC could strengthen their work through the use and the integration of Geographic Information Systems.
