Fabrice Marr of AEROmetrex discusses the growing role of 3D models in engineering and infrastructure projects in this article. Photogrammetry techniques are being used to create 3D models of natural and urban environments, and could be an alternative to Lidar. "3D photogrammetry has a major role to play in this initiative with the possibility to quickly generate, at an affordable cost, photorealistic and geographically accurate 3D models of urban and natural environments," he writes.
