For an airport runway project requiring a 3D model built from overlapping photos and readings from SONAR, RADAR, and LiDAR, which concept or tool MUST the survey team use?

• A. 5G
• B. Artificial intelligence
• C. BIM
• D. Photogrammetry

Answer: (D)

Photogrammetry is the process of deriving accurate 3D geometry from overlapping photographs by using the parallax between images. Since this project requires building a 3D model from photos that overlap, this technique is the natural and necessary method to reconstruct the runway surface and surroundings in three dimensions. The resulting model can be enhanced by integrating readings from LiDAR (and other sensors) to improve accuracy and fill gaps, but the essential step for turning the photos into a usable 3D representation is photogrammetry. Other options don’t directly address turning overlapping imagery into geometry. 5G is just a communications standard with no role in generating 3D models. Artificial intelligence can assist in processing data, but it isn’t the required method for producing the 3D model from photos. BIM is a broader model for building information management and isn’t the specific technique needed to produce a 3D surface from images.
