The role of 3D mapping of collapsed areas in the INACHUS project is to provide the USaR personnel with accurate and timely 3D models to support situation assessment, localization of survival spaces and rescue paths and planning of actions. To be able to do this as efficiently as possible, a strategy is needed for how and when the respective 3D mapping systems should be used and how their respective strengths should be exploited, so as to offer maximal support in the search and rescue phase. The 4-main objectives are detailed hereafter:
Wide-area disaster scene assessment based on nested integration of space-borne information and Finite Element Method (FEM) results, and population distribution mapping, for 3D modelling and USaR prioritization,
Provide high resolution and high quality 3D Digital Surface Models (DSM) coming from laser cameras and photogrammetry data on the most affected areas,
Perform an exploitation of this 3D data in relation with the library of collapsed building models using a semantic analysis or matching method,
Assess the structural damage to deliver maps of survival space and rescue path.
