Using LiDAR points fused with RGB imagery values, WSI generates true 3D visualization and animation products for hydroelectric dams, penstocks and powerhouses. Since these structures are located in areas that are difficult to access due to challenging terrain, these tools are valuable in viewing the as-built infrastructure conditions as well as the terrain and surrounding vegetation. High resolution terrain models and feature-extracted and coded LiDAR data are also delivered in the client-specified format.
