Interior scanning of structures that have ceiling tiles, like grocery stores, presents a challenge for efficiency and accuracy for surveyors. Bowman took on this challenge to develop a new and proven technique that is simple, elegant, accurate, and most of all, repeatable in other environments. Prior to developing this technique, ground level 3-D scanning in an open interior environment was simple enough. However, tying that information to the scanning data above the ceiling tiles was difficult unless they were all removed, which is inefficient and time consuming. For Bowman’s geospatial team, the key was finding a way to tie the scans vertically throughout the space at different elevations, then mapping them horizontally to develop the entire landscape of the structure. Cuhaci Peterson was specifically looking for a national partner who could provide this type of service, in a timely manner and within their data requirements, for structures that were 60,000-100,000 square feet.
