The Leader in Drone-Based Geophysics Technology

 

Soaring to New Discoveries: Drone-based Geophysics

Drone-based geophysics is the use of unmanned aerial vehicles (UAVs), also known as drones, to carry out geophysical surveys. 

These surveys map the physical properties of the Earth's subsurface by measuring things like magnetism, electrical conductivity, and natural radioactivity.

Geophysics, the study of Earth's physical properties, is getting a lift thanks to drone technology. Traditionally, geophysicists relied on ground-based surveys, which can be slow, labor-intensive, and dangerous in difficult terrain. Drones, also known as Unmanned Aerial Vehicles (UAVs), are revolutionizing the field by offering a faster, safer, and more cost-effective way to collect geophysical data.
