Application of 3D Remote Sensing Technology in Aided Design of Low Altitude Magnetic Survey Flight

Using remote sensing technology, GIS technology and virtual reality technology, the remote sensing image and DEM data are superimposed to establish a three-dimensional remote sensing image model of the low-altitude magnetic survey flight work area. The three-dimensional model can clearly reflect the distribution of surface vegetation, rivers, wetlands and other ground features with topographical features, and can design flight routes based on survey lines to achieve simulated flight and generate three-dimensional animations. In the preparatory stage of flight work, simulated flight animation can visually display terrain undulations and surface coverage to technical personnel, guide the deployment of flight work, and provide decision support for large-scale low-altitude aeromagnetic surveys.
