LiDAR has always presented a useful option for engineering road design work, however it has also brought engineering software limitations to the forefront due to cumbersome file size, which is inherent with raw LiDAR point clouds, especially those generated from high pulse-rate systems.
LiDAR point clouds can frequently produce multi-million point files that cannot be managed by software typically used on the engineering side. Terra has overcome this limitation. Through extensive work with civil and transportation engineers, Terra has developed techniques and internal software applications to efficiently extract essential data from LiDAR point clouds into features readable by engineering software, including:
- Critical terrain feature extraction (enforced by breaklines) from high-density LiDAR datasets, producing a low-volume and accurate surface model.
- Supplemental vector feature delineation (paint lines, edges of pavement, curb offsets or building footprints, etc.) derived from aerial photography.
- Seamless data integration into a single topologically correct package compatible with any standard CAD/GIS software (AutoCAD, Civil3D, ArcGIS, CAiCE, Softree, ISTRAM, etc).
