Lidar uses precise lasers to produce digital, three-dimensional, representations of surfaces. A lidar sensor emits laser pulses and measures the time each pulse takes to bounce off a surface and return to the sensor. Each return is stored and becomes one of billions of data points used to create a digital visualization of the scanned target. Lidar sensors are incredibly mobile, and can be operated from handheld devices, vehicles, and aircraft to produce digital models that are rich in metadata.
The versatility of these sensors and the accuracy of the results has allowed lidar to become integral to a variety of different industries. Digital models act as a snapshot of the real-world, and can inform construction projects, track environmental change, guide autonomous vehicles, reveal archeological wonders, and document infrastructure, among many other uses.
Lidar data is collected using Riegl’s newest lidar sensors and embedded with positional information from an Applanix AV610 IMU and AV39 antennas. Sensor configurations can be rigged to drones, helicopters and airplanes using FAA-approved mounts. NV5 Geospatial also provides ships for deep sea modeling using multi-beam sonar, and backpack and terrestrial lidar.
Beyond designing our own scanner systems, the GEO1:1 team evaluates every project with a new perspective to determine the best sensor platform. Our sensors work on drones, helicopters, airplanes, and ground vehicles.
Wide Area Mapping
”The GEO1 Multicam represents the future of aerial production work. As an aerial cinematographer, the 3D imagery acquired from the helicopter provides the VFX supervisor with endless options in comparison to the fixed perspective of shooting plates.”
