Published on

Light-imaging Detection and Ranging (LiDAR) has become a common tool used in mapping and is being dispatched to complete more and more projects, but do you understand what this technology is, how it works, and what it can be used for? Through this brief but informative presentation, we’ll get you up-to-date on LiDAR
technology and its ability to offer acquisition of digital elevation data for large-scale mapping projects. We’ll also
discuss how LiDAR can work alongside traditional aerial photography and photogrammetric techniques – making it even more powerful.
