Due to the low cost of deploying drones, you'd be able to gather aerial images or video on a regular basis to develop 3D models. The ease with which you may capture visual data allows you to generate real-time 3D models that would be prohibitively expensive if done by helicopter. You can create a digital surface model (DSM), a digital elevation model (DEM), or a digital terrain model (DTM) using 3D data (DTM). In a Point Cloud, a 3D visualization made up of thousands or possibly millions of geo-referenced points can be created. High-resolution data and an interactive 3D model with real-world pictures are provided by point clouds. These can be used to inspect the job site or to offer detailed information on how the job is proceeding on-site to clients or stakeholders. Additionally, point clouds may be utilized to create digitized models of structures for use in CAD and BIM applications.
