This keynote presentation will revisit some of the fundamentals behind lidar that influence the precision and detail the systems produce. The laser ranging systems that are used strongly influence how the lidar system works and factors including: wavelength, beam divergence, pulse width and pulse repetition frequency will be reviewed and discussed. Most airborne topographic lidars use a 1064 nm Near-Infrared laser, while topo-bathymetric lidar systems deploy both a NIR laser and a green laser...

Traditional LiDAR acquisition platforms are commonplace in the industry and can be relied upon for efficient data acquisition for most relatively flat and uniform project areas. However, when multisource data acquisition is required or acquisition is impacted by complex corridors, excessive terrain, low-hanging clouds or airspace limitations, alternative approaches are required. This presentation will highlight some of NV5’s innovations to address these challenges including the Comprehensive ...
