Mobile Scanning: Surveying at the Speed of Innovation
Because of its safety, quality, accuracy and efficiency, mobile scanning technology has revolutionized the way accurate pavement data is captured in the field for design purposes. MoDaC Mobile Data Collection® is McKim & Creed’s innovative mobile scanning system, and makes McKim & Creed one of the few firms on the East Coast and in Texas to offer turnkey mobile scanning services.
Mobile scanning combines 3D laser scanning, GPS, inertial measurement and video technologies. Multiple scanners are mounted on an SUV, a rail truck or a survey vessel. These scanners collect dense and accurate 360-degree data while the vehicle travels at posted speeds. The data is used for design, modeling and simulation in 2D, 3D and 4D formats.
Mobile scanning offers considerable benefits. It is more cost effective than many traditional surveying technologies. Data collection is much faster. Massive amounts of data can be collected while traveling at posted speeds, and surveyors can collect up to 400,000 points per second, as compared to one point every few seconds with traditional surveying. With fewer personnel working beside busy roadways, mobile scanning creates a safer job site. The likelihood of bad-weather delays is reduced due to shortened data collection time. Because the data is collected from a moving vehicle, mobile scanning does not impede traffic flow. And the dense data that is collected lends itself to future data extraction without additional field visits.
