Mobile LIDAR, compared to its aerial counterpart, can provide 10 to 100 times more data points that hugely improve the resolution of an image. Moving even at highway speeds, a technician can obtain a remarkable, three-dimensional view of the nearby terrain.
Such technology could be used repeatedly in one area and give engineers a virtual picture of an unstable, slow-moving hillside. It could provide a detailed image of a forest, or an urban setting, or a near-perfect recording of surrounding geology. An image of a tangle of utility lines in a ditch, made just before they were backfilled and covered, would give construction workers 30 years later a 3-D map to guide them as they repaired a leaking pipe.
Mobile LIDAR may someday be a key to driverless automobiles, or used to create amazing visual images that will enhance "virtual tourism" and let anyone, anywhere, actually see what an area looks like as if they were standing there. The applications in surveying and for transportation engineering are compelling, and may change entire professions.
Just recently, mobile LIDAR was used to help the space shuttle Endeavour maneuver through city streets to reach its final home in Los Angeles.
Some of the newest applications, Olsen said, will have to wait until there are enough experts to exploit them. OSU operates one of the few programs in the nation to train students in both civil engineering and this evolving field of "geomatics," and more jobs are available than there are people to fill them. Due to a partnership with Leica Geosystems and David Evans and Associates, OSU has sufficient hardware and software to maintain a variety of geomatics courses. But more educational programs are needed, Olsen said, and fully-trained and licensed professionals can make $100,000 or more annually.
