We keep innovating
Our data processing utilizes unique probabilistic techniques that allow you to offer better data and reduce collection costs.
We design innovative LiDAR processing solutions for airborne and terrestrial laser scanning. We analyze, model and process your data to make laser ranging enter the information era; we also help you define the data collection requirements that best fit your needs.
Our custom LiDAR processing software deliver unmatched performance. We develop specific, highly optimized software that can run on multiple platforms. Your benefits: improved accuracy, reduced project costs, plus remote calibration and full support.
Our expertise: LiDAR & image processing using Bayesian inference and probabilistic modeling. Learn more about the founder, his academic publications, and recent LiDAR-related projects.
Custom processing solutions for higher quality laser scanning
Frustrated with money-wasting practices such as flight line edge cutting, flying low, and calibration lines? We leverage the power of Bayesian inference to make the best use of all available data without throwing away useful information. Our approaches allow you to fly higher and still get high quality results, thus reducing collection costs. And use only regular flight lines to perform alignment and calibration tasks.

Attitude and position errors are one of the major source of uncertainty in airborne LiDAR. Thanks to swath overlaps, these errors can be reduced using a procedure called strip adjustment. Points clouds are automatically registered onto each other which effectively decreases discrepancies between swaths, and improves relative and absolute accuracy.
