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.
Since that time, 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.
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.
We also provide Mobile LiDAR for transportation projects. We utilize 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. The 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.
Remote sensing has proved to be an invaluable asset facilitating the study and design of lengthy transit and energy corridors. Utilizing our Leica RCD30 Digital Sensor, we can collect highly accurate digital imagery and contour data for corridor analysis.
Applying state of the art remote sensing methodologies, we have completed aviation and airfield projects throughout the Southeast and Caribbean. From Airport Master Plans to Aeronautical Obstruction Surveys and Line of Site Studies, I.F. Rooks has decades of experience assisting airport authorities and aviation consultants in expansion and safety enhancement of international and regional airports.
Remote sensing has long been an effective tool to study and manage environmental assets. Working for Water Management Districts, the Army Corps of Engineers and numerous environmental agencies, we have provided orthophotography and elevation data for the study and management of wetlands, sea grass beds and coastal environments.
