3D Virtual Reality Model of a Landslide in Urban Area

Abstract. This work presents a methodological approach for developing a 3D Virtual Reality model of a landslide in the urban area of the municipality of Petrópolis, State of Rio de Janeiro, Brazil. The 3D virtual reality model was generated from data obtained by Unmanned Aerial Vehicle, 3D modeling, and data integration in an immersive and interactive geovisualization environment. Some images from before the event were used to reconstruct the buildings on the hillside, and 3D modeling was carried out using parametric rules. The generated model can be used in a virtual reality room (for a team experience) or with virtual reality glasses (for an individual experience). Although the Virtual Reality models do not replace fieldwork, they aid in understanding the landslide triggering process and analysing the impact caused and have the potential to be used in educational projects for disaster prevention and risk reduction.
