Modelagem 3D e geovisualização aplicada a desastres naturais. Uma proposta de laboratório de ensino e pesquisa para monitoramento e previsão de escorregamentos

Landslides have a high degree of uncertainty requiring new methods for their analysis, monitoring and forecasting. In Brazil, Cemaden is responsible for actions related to the natural disasters and, recently, has started with partner institutions, a project sponsored by FINEP in order to monitor ten prone-landslides areas situated in different regions of the country. This paper presents the proposal of REDEGEO to implant a laboratory of modeling and geovisualization to study landslide processes in urbanized areas. 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 (Resistivity and Radar Soil Penetration - GPR); B) 3D modeling using the software Geovisionary® which allows the analysis of image and geophysical dataset from different formats 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 a laboratory related to the natural disasters, which include 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.
