Our results have raised the profile of our multi-sensor fusion technique and given us the confidence to pursue similarly challenging projects." — Klaus Legat, Head of Photogrammetry and Aerial Survey, Vermessung AVT © 2019, Trimble Inc.

Credit: OEBB AVT then needed to precisely georeference the MX7 imagery to map objects that couldn't be seen in the aerial images. After determining the path of the MX7 using the accurate GNSS/INS data recorded during the ride, they manually selected several hundred 3D points that had been determined as multi-ray TPs (aerial GCPs) within MATCH-AT. Those were used to orient the MX7 images to ensure the maximum consistency between the aerial and mobile-mapping data. They then extracted and mapped the mobile-mapping objects and exported the results to AutoCAD to produce the finalized 3D vector map showing the specific layers and symbols defined by the ÖBB. Both the 2D orthomosaic and 3D vector map were delivered to the ÖBB in August 2017 and the authority conducted several independent evaluations to assess the quality and accuracy of the datasets. AVT's results were not only given full approval, the successful proof- of-concept has led to further work with the ÖBB and piqued the interest of other organizations who service alpine communities
