At Spectral Sky we sell the Geodetics Geo-MMS (Velodyne VLP-16 Puck LiDAR integrated with high-end GPS/IMU). We also sell the complete turn-key package that includes all hardware, software and training support you need to begin using LiDAR. Please PM me if you would like more info.
@Neil Backer - what application do you have in mind? Is this for high precision mapping, altitude control, collision avoidance or something else?
