LiDAR Processing Software


Quick and efficient processing of UAV & mobile mapping data

CoPrelidar data processing software is a powerful and intuitive software ecosystem for quick and user-friendly processing of geospatial data gathered by UAVs and mobile mapping platforms. Supporting all our LiDAR scanners, it provides immediate access to raw data and includes automated workflows for maximum efficiency.

The software provides a variety of useful features including accurate trajectory processing, point cloud and image georeferencing, point cloud colorization, filtering, and digital ortho model (DOM) generation.


Advanced post-processing software for massive point cloud datasets

CoProcesspost processing software is an advanced software package designed for the post-processing of massive point cloud datasets. Providing both automatic and manual extraction and classification of features such as ground, vegetation, buildings, roads, power lines and more, it transforms raw data captured by UAVs and mobile mapping vehicles into a variety of multi-format deliverables.

The software features a comprehensive set of capabilities including DEM and DTM creation, volume calculation and analysis, and output to DAT or DXF format for seamless integration with leading software such as AutoCAD and ArcGIS.
