LiDAR rectification module for ALTM users

Toronto, Canada: Optech Inc. released Lidar Mapping Suite (LMS) version 2.0, for their Airborne Laser Terrain Mapper (ALTM) clients. An all-new LiDAR rectification module provides additional value by maximizing and quantifying project-wide accuracies.

Optech LMS offers ALTM clients an all-new workflow designed specifically for the production environment. Incorporating a fully-automated batch-mode capability, Optech LMS enables simultaneous processing of multi-mission data collects and includes multi-threaded and distributed processing capabilities to further increase processing efficiency.

Michael Sitar, Optech’s Airborne Survey Products Manager, said, “Optimising LiDAR data accuracies by minimising flight-line to flight-line variations is a standard workflow process. By incorporating our proprietary LiDAR optical models, we are able to offer a workflow that enables raw LiDAR point files to be exported directly to value-added software without further refinement. This can pay dividends in maximising the efficiency of the LiDAR production environment.”

Optech LMS also includes pre- and post-rectification results, as well as relative and absolute accuracy comparisons. Results are available as a project deliverable in the form of reports, plots and graphic comparisons. Coupled with robust underlying algorithms that have been field-proven for more than two years, it largely eliminates the need for independent calibration flight regimes.
