With the addition of a new state-of-the-art Leica ALS40 Airborne Laser Scanner, EarthData (Manassas, Va., USA) has expanded its sensor suite to meet an even wider range of client needs for elevation data. The new system augments the company’s existing LIDAR capability with multi-return intensity capture at greatly increased pulse and scan rates as well as automatic roll stabilization, critical components for efficient production of high-resolution LIDAR-derived elevation data.

Steve DeLoach, Vice President, EarthData Technologies, the group’s research and new technology development arm, explained that the decision to acquire the new Leica system was driven both by client demands for high resolution LIDAR data and the company’s commitment to constantly increase production efficiency in all areas of the business. “The ALS40’s extremely dense, balanced scan patterns will meet the growing demand for high-resolution elevation models, where high pulse and scan rates are critical.” He added that the combined capabilities of the two systems make EarthData’s LIDAR service unique in the industry. “With these two systems, EarthData can acquire LIDAR data from 1,500 – 30,000 ft, with accuracies ranging from 7-30cm, meeting the wide range of client needs for elevation data in the most cost-efficient, timely manner.”
