LiDAR, short for light detection and ranging, is a remote sensing technology that uses light in the form of a pulsed laser to measure ranges (distances) to a target. A LiDAR sensor fires off beams of laser light and then measures how long it takes for the light to return to the sensor.
The costs of building and using LIDAR systems are coming down because it’s becoming easier and cheaper to collect more and more data, and LIDAR is being used in more applications.
At Techwave, we strive to be a world-class lighting technology provider. With that role comes the responsibility to be intimately familiar with newer applications and help our partners understand the real value in them.
Techwave has been innovative in our ability to seamlessly integrate point cloud datasets from multiple LiDAR sensors such as airborne LiDAR systems, stationary scanning systems, and vehicle-based or “mobile mapping” scanning systems.
- Applications include
- Engineering design level topographic mapping
- Terrain modeling for floodplain management
- Electrical transmission utility as-builts
- Urban forestry, and many others.

THE 3D FIBER DESIGN PROCESS
- LiDAR Collection team is dispatched to the route created based on customer input and job requirements by the Work Preparation Team.
- After a brief setup time at the job location starting point, the route is driven and data is collected. Data is recorded to the on-board PC.
- Data is transferred to a portable SSD drive via USB3 and shipped via FedEx to the local Delivery Center.
Design & Submit
- The dataset is prepared for the design teams use in production. Differential correction, RGB colorization, and trajectory alignment.
- Design team begins feature and measurement extraction, applying the required measurements and attributes to the design files.
- Outside plant design specifics are now applied and the design is finalized.
- Final quality check of the project is completed referencing the LiDAR data.
- Permits are created as required.
- Work package is finalized and delivered to the customer
- Web-based user experience, both internal and external, reduces the office skillset and increases availability across multiple GEO in the organization.
- Ability to provide LiDAR data as a service expanding our client offerings; new revenue stream.
- Tool development to semi-automate feature extraction and Landbase creation.
