Realistic 3D city modeling at large scale

The Metropolis of Nîmes wanted to get a very realistic 3D models of its territory (700 km², 27 cities). This 3D basis had to be used for territorial marketing, analysis of the impact of urban projects, along with as a decision-making tools for land management, and communication.

SIRADEL produced more than 150.000 building in 3D LOD 2 (photogrammetry), the terrain and a true orthophoto from aerial stereo images at very high resolution (5 & 10 cm). More than 20 km linear of roads has also been textured with high definition pictures thanks to our Mobile Mapping System embedded on vehicle. Finally, dozens of building landmarks, such as the arenas, have been modeled in 3D LOD 3 (3D computer graphics).
