Knowledge base

We know LiDAR technology and UAVs. We get involved in research projects on LiDAR for drone, conduct our own tests, have regular discussions with people that are affected by LiDAR in some way.

We now want to share this knowledge with anyone interested in knowing more about how LiDAR works. We have therefore gathered our extensive knowledge about LiDAR mapping in one place to make it easier for you to learn more.

You can learn about upcoming technologies, read in-depth articles on different LIDAR-related topics, take part in research results or perhaps plunge into our comprehensive LiDAR mapping knowledge bank – the choice is yours!
