LiDARUSA builds systems for clients around the world that are interested in minimizing their time on-site and maximizing data collection. Once a project is captured, processing begins in the field. Trajectories are processed to refine the positioning and provide EO data for the imagery. The lidar data are refined and exported to las/laz format. The lidar data are then imported into Correlator3D and converted into a DSM and an intensity image. These are then used to extract additional GCPs for the aerial triangulation process. This ensures proper registration between the lidar and imagery. The lidar derived DSM then allows to move right to orthorectification and mosaic production. Once the mosaic is completed, the original lidar file is colorized using the mosaic. This adds an additional visual intelligence value to the lidar data, easing its interpretation.
Typical deliverables that are produced by LiDARUSA’s integrated systems include orthomosaics and colorized point clouds.
The benefits of using Correlator3D according to LiDARUSA is the ability to use the lidar as control for the imagery, especially when access may be difficult. Additionally, the ability to use imagery to colorize the lidar point cloud. Ultimately, the solution allows to make the deliverables more accessible to all stakeholders.
