Nora Csanyi, the lead author for the paper, “Improvement of Lidar Data Accuracy Using Lidar Specific Ground Targets,” will receive the BAE Systems Award at the 2005 Annual ASPRS Conference in Baltimore later this month. This is the first time the award, created by BAE Systems, will be given. Csanyi is with the Department of Civil and Environmental Engineering and Geodetic Science Center for Mapping, The Ohio State University.
Csanyi’s paper dealt with engineering scale mapping of highway corridors that frequently require extremely high accuracy. Lidar technology offers an excellent tool to accomplish this task; lidar systems are complex multi-sensory systems, incorporating GPS and INS navigation sensors, and the laser-scanning device. The high complexity of the system, however, results potential error sources that can degrade the accuracy of the acquired Lidar data. One way to achieve the high accuracy required by engineering scale mapping is using well-identifiable lidar-specific ground control targets. This paper is a continuation of a former paper titled “On the Use of Lidar Specific Ground Targets” presented at the ASPRS Conference in Denver, 2004, where design of the optimal lidar targets, including shape, size, and signal response was discussed and some initial, limited experiences were presented. Since then, additional tests were performed to further investigate the potential of using control targets for lidar data refinement. This paper provides a detailed performance analysis, investigating the achievable lidar data accuracy improvement using lidar-specific ground control targets.
The BAE Systems award was created to reward top quality research and publication by young students (under age 35 as of the application deadline) at the master’s or doctoral level and to encourage researchers to use the ASPRS annual conference as a vehicle to publish and present their findings. The recipient’s paper will be published in Photogrammetric Engineering & Remote Sensing (PE&RS), the official journal of ASPRS. This award is presented by the ASPRS Foundation with funding provided by BAE Systems. The award consists of a hand-engrossed certificate and a grant of $2,000.
Founded in 1934, ASPRS is an international professional organization of 6,000 geospatial data professionals. ASPRS is devoted to advancing knowledge and improving understanding of the mapping sciences to promote responsible application of photogrammetry, remote sensing, geographic information systems and supporting technologies.
