This lecture, "From Walking to Flying: Sharing Advanced Surveying Technologies from Point to Area," profoundly revealed how modern surveying technology is revolutionizing the perspectives of traditional geography and historical spatial research. The themes of "from walking to flying" and "from point to area" not only vividly illustrate technological evolution but also foreshadow a paradigm shift in spatial information acquisition methods. In the past, traditional surveying heavily relied on manual labor, using total stations or GPS for isolated "point-like" observations. This was not only time-consuming and labor-intensive but also made it difficult to grasp the overall terrain. However, modern advanced surveying technology has introduced diverse vehicles such as unmanned aerial vehicles (UAVs), airborne laser scanning (LiDAR), and satellite telemetry, enabling the collection of spatial data to truly "fly." This technological innovation allows us to conduct large-scale and continuous "area-like" panoramic scans from high altitudes. The application of 3D laser scanning and real-world 3D modeling technologies. These technologies can transform complex surface features and historical structures into high-density digital point cloud data. For geographical research, this enables more accurate simulation of topographic changes, disaster prevention, and urban planning; for historical research, it provides a scientific basis for digital cultural heritage preservation and historical site restoration. Modern surveying is no longer just simple "map making," but a cutting-edge science combining massive amounts of data, artificial intelligence, and 3D visualization. As students of history and geography, we cannot remain limited to traditional documents and static maps; we should actively embrace these advanced technologies. Through spatial technology tools that move "from point to surface," we will be able to tell the story of the land more powerfully and gain insights into the past, present, and future of the relationship between humans and the land.
