This NEON Science video overviews what lidar or light detection and ranging is, how it works and what types of information it can provide. The video was produced by the National Ecological Observatory Network - a non profit project devoted to open science and open data.

http://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/f2017/cdg79/cdg79/cdg79/cdg79_finalproject_website.html The goal of this final project was to create a lidar 3d imaging system while on a limited budget. This is a system which takes many distance readings while pointing at many different angles. These distance readings are then converted into cartesian points and then plotted onto a graph. By plotting thousands of points, a three-dimensional image of the scene the system is pointed at is created.
Use a Phoenix LiDAR drone surveying system to generate precision environmental data for many applications. In this case, LiDAR mapping of power lines enables companies to "see" through encroaching vegetation, generate color 3D point clouds, and analyze elements of the environment, including line sag, elevation, types of objects/structures, and more. This video was developed for a Phoenix LiDAR presentation at the DJI AirWorks 2017 event in Denver, Colorado.
The future of autonomous driving is on its way. The Velodyne LiDAR system consists of 4 HDL-32E LiDAR sensors mounted on the top of a car. This system is used to explore autonomous driving in a car. The lasers take 3-D measurements 20X's per second of the car's surroundings to generate 700k data points. The result is a real time image showing the surrounding environment.

Encoders are a key part of vehicular LiDAR systems that are used to accurately map vast road infrastructure. Read the application note: www.renishaw.com/lidarapplication LiDAR scanning systems provide precise and accurate co-ordinate measurement data that is used to create realistic and detailed 3D city models viewable from street-level. LiDAR scanning systems consist of a laser range-finder with rotating scan mirror and various positioning and orientation systems. These systems capture 360° 3D point cloud data whilst rotating at more than 1000 RPM. Renishaw's ATOM™ encoder series is perfectly positioned to meet the challenges of high performance in a small footprint. The ATOM encoder is also the world's first miniature encoder to employ advanced filtering optics.
This video is an overview of the Phoenix Aerial AL3-16 LiDAR Mapping system. The AL3-16 can be mounted on any UAV that can lift 2.5kgs. In this video, a DJI S1000 is used and for the demonstration, we flew over an over an open pit. You can see how quickly we generate a dense pointcloud. You'll also see how LiDAR can pick up points underneath vegetation vs Photogrammetry will only map tree canopy.
This video gives you step-by-step instructions on mounting our Snoopy system to a vehicle. See www.lidarusa.com for more information! NOTE: The video says to "hand tighten" the screw on the mount, but if you feel it is absolutely necessary, you may use an allen wrench to tighten even further. Just make sure not to over tighten!

Mobile LiDAR scanning collection system coupled with automated data extraction can process up to 40 bridges per day. Accurate data on vertical clearances of roadway structures is critically important in oversize route planning. Horizontal clearance measurements must also be maintained. Traditionally collecting this data can be dangerous or can cause congestion with work crews subject to significant traffic hazards. Work must be performed during available traffic breaks which can induce errors. From a system-wide perspective clearance information in many cases is incomplete, inaccurate, difficult to maintain and difficult to access. Obtaining survey grade accuracy at traffic speeds is the proven, most efficient way to accurately measure various structures and roadway features.
