Drone software enhances lidar point cloud handling

August 5th, 2019, Published in Articles: PositionIT

Virtual Surveyor has enhanced the lidar elevation data handling capabilities in Version 6.4 of its drone surveying and mapping software. The new function enables users to select specific feature classes from classified lidar point clouds before converting the point cloud to a surface terrain. The software bridges the gap between UAV photogrammetric processing applications and engineering design packages. It generates an interactive onscreen environment with UAV orthophotos/DSMs and/or lidar point clouds where the surveyor selects survey points and breaklines to define the topography. In version 6.4, users can import a lidar point cloud that has been classified by elevation in a third-part software into feature classes. Users can then select one or more classes for visualisation and further processing into topographic products. A second new function in the software is the ability to integrate two types of data to create a single cohesive scene. This feature will most often be used to merge bathymetric survey points acquired underwater with traditional photogrammetric imagery captured by drones. Version 6.4 also enhanced mosaicking functionality.
