Airborne Corridor Mapping
The collection of dense and accurate LiDAR data of corridors has a variety of applications. The three main ones are for Electric Transmission lines, gas and liquid pipelines, and transportation corridors.
Electric Transmission
Electric Transmission lines need to be frequently monitored to determine the status of their components as well as their proximity to vegetation. Three dimensional models of these facilities are built using the LiDAR data. Line sag, points of attachment, tower positions and vegetation clearances are all determined from these models. These models facilitate the reengineering of these lines to increase their capacity as well as the selective trimming of rapidly growing vegetation along the lines.

Pipeline and Transportation
Airborne LiDAR data for corridors also has a great deal of utility for pipelines and transportation corridors.
Underground Pipelines for both liquid products and natural gas benefit from having a detailed elevation model of their corridor. One of the first applications in this industry sector has been providing elevation models for the production of orthophotography. Orthophotography is an important part of the determination of High Consequence Areas, or HCAs, which is a critical part of implementing and maintaining the integrity management plan required of all pipeline operators by the Federal Office of Pipeline Safety.
Other applications of high-quality three dimensional data are beginning to take hold in this industry. The determination of geologic hazards is a very important one. In the planning of pipelines transporting liquid products it is crucial to determine low areas where the material would accumulate if a spill occurs, and the LiDAR data provides an excellent solution for this determination.

Pipeline
Airborne LiDAR data has shown its utility for both rail and road corridors, both as a standalone product and in concert with ground mobile data. Rail and road corridors frequently need data sets that exceed the range and visibility of ground collected data.
The rock fall application provides an excellent example of the utility of aerial LiDAR data. Naturally occurring hazard areas require the combination of both ground and aerial data of the corridor in order to successfully generate the needed product.
TITAN® Variant recommended:
TITAN Universal is the only system of its kind in the world. It is a combination of a ground mobile LiDAR unit, and an airborne LiDAR unit that share a common IMU, computing system, and software. This results in a dramatic increase in the utility of the components and a reduction in cost of the overall system as compared to buying two standalone units. The scanners on both units are optimized to the specific applications of the client. The shared operating and processing software allow for commonality in acquisition and production processes, thereby optimizing personnel training and deployment.
