Low Altitude Mapping

In response to traffic related surveyor injuries and the continuing need for design-quality survey information on our congested roadways, I.F. Rooks began providing Low Altitude (Helicopter) Mapping to the DOT and consultant community starting in 1999.

What is low altitude Mapping?

We have completed Low Altitude Mapping design surveys projects on over a thousand miles of roadways throughout the South Eastern United States. Because of the survey accuracies achieved, and the reduced risk to ground survey consultants, Low Altitude Mapping is an excellent methodology for roadway design projects, including road widening, resurfacing and concrete rehabilitation.

current Uses for low altitude mapping

Low Altitude Mapping addresses critical safety issues and eliminates the need to close busy travel lanes or place ground survey consultants in the middle of, or immediately adjacent to, congested, high traffic corridors. In addition to accuracy and safety, the utilization of Low Altitude photogrammetry on roadway projects will result in time and cost savings over other survey methodologies.

Mobile LiDAR

We also provide Mobile LiDAR for transportation projects utilizing a RIEGL VMX 450 Mobile LiDAR system. This system allows us to safely collect LiDAR data along roads and railroads at Interstate speeds (up to 70 mph) during the day or night. The VMX - 450 is the most effective and efficient mobile LiDAR system on the market today.

VMX System

The VMX system integrates two laser scanners as well as inertial measurement and GNSS equipment, housed under an aerodynamically shaped protective cover. The system also includes a well-designed camera platform allowing us to mount and setup up to six high-resolution digital cameras. The VMX system is modular in design to allow a quick setup on different vehicles (or vessels, rail cars) and provides our client’s with a fast highly-accurate laser ranging system.
