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 natural disasters. Recently, it started, with partner institutions, a project sponsored by FINEP in order to monitor ten landslide prone areas located in different regions of the country. This paper presents the proposal of REDEGEO to implement a modeling and geovisualization laboratory 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 utilizing geophysics methods (Resistivity and Ground Penetrating Radar – GPR) to obtain internal geometry of outcrops; (B) 3D modeling using the software Geovisionary®, which allows the analysis of image and geophysical datasets in different formats, considering their volumetric properties; (C) Geovisualization and Virtual Reality (VR), allowing images obtained in the field to be observed from a human-machine interface, so that researchers can have full immersion in the selected areas. The creation of a laboratory related to natural disasters, including geovisualization and VR capabilities, stimulates the active participation of research teams and creates mechanisms for participation by technology developers, managers, civil defense agents and even the population living in risk-prone areas
