This presentation showcases the evolution of drone-based GIS, moving beyond traditional 2D aerial imagery to create rich 3D models by exploring Simultaneous Localization And Mapping (SLAM) lidar technology. Attendees will gain valuable insights into the combined use of these hardware platforms and explore standard processing techniques, such as Structure from Motion (SfM) and the innovative 3D Gaussian Splatting method. The session will highlight practical workflows and feature examples of 3D models that have been generated.
