What is the visual impact of a wind turbine? What are the risks of floods when a dam breaks? How do electromagnetic or audio signals propagate? ...: Replying to these questions requires information about terrain and objects heights. As described in “Our Expertise/DSM-DTM”, EUROSENSE provides accurate and detailed elevation models using either laser altimetry or photogrammetry.

Height information is delivered in various formats: point clouds, TINs, grids,... . Depending on your purpose, elevation data contain only ground surface (e.g. for normal orthophotoproduction - DTM), object surface including specifically the buildings (e.g. for production of Nadir Orthos) or object surface including all objects (DSM).

Height data provide also essential information in other applications such as localisation of insulators on powerlines or obstacles above pipeline trajectories. EUROSENSE identifies specific objects applying a filtering and classification method on point clouds. Terrain profiles provide additional information on a specific line trajectory.
