In the fields of surveying and geological exploration, industrial drones have completely subverted the traditional operation mode with their high-altitude perspective and high-precision data collection capabilities. Surveying drones are equipped with an RTK positioning system with centimeter-level accuracy, a high-resolution optical camera, and an oblique photography module. A single flight can cover an area of 50 square kilometers, quickly obtain three-dimensional point cloud data of the earth's surface, and generate professional results such as DEM (Digital Elevation Model) and DOM (Digital Orthophoto Map), with an efficiency increase of more than 80% compared with manual surveying. Its wind resistance capacity reaches level 6, and it can operate stably in high altitudes (up to 5,000 meters) and complex climatic conditions, easily reaching mountains, forests, and deserts that are difficult for humans to access.
The core value of drone surveying lies in the real-time and integrity of the data: Through automatic route planning, it can conduct a comprehensive scan of mining areas, urban building complexes, and river basins. The millimeter-level accurate image data provides a reliable basis for engineering design, land planning, and disaster assessment. The supporting post-processing software supports the one-click generation of three-dimensional models. Engineers can measure distances and analyze the terrain through a virtual scene, greatly shortening the project's preliminary research and investigation cycle. In geological exploration, the infrared thermal imager and spectrometer carried by the drone can quickly identify the distribution of minerals and the structure of the strata, providing an efficient solution for mineral resource exploration.
From urban 3D modeling to national land space planning, surveying and exploration drones are becoming the "aerial eyes" of the geographic information industry. Their lightweight design and rapid deployment capabilities make large-scale data collection convenient and efficient, promoting the transformation of the surveying industry from "manual single-point measurement" to "full-domain digital modeling." With the advancement of the construction of a real-scene 3D China, drone surveying will play a more important role in fields such as smart cities, emergency management, and environmental protection, reshaping the way humans perceive the geographical space with technology.
