1. New Technology and Service, Innovation
Drone geophysical surveys involve using unmanned aerial vehicles (UAVs), commonly known as drones, to collect geophysical data over a specified area. These drones are equipped with various sensors capable of measuring different physical properties of the Earth’s surface and subsurface. The data collected from drone surveys can provide valuable insights into geological features, environmental conditions, and resource potential.
Some common types of geophysical surveys conducted using drones include:
- Magnetic surveys: Drones equipped with magnetometers are used to measure variations in the Earth’s magnetic field. These variations can indicate the presence of subsurface geological structures, such as mineral deposits or faults.
- Electromagnetic surveys: Electromagnetic sensors mounted on drones can measure variations in the conductivity of the Earth’s subsurface. This information is useful for mapping groundwater resources, identifying geological formations, and locating buried objects or utilities.
- Thermal surveys: Drones equipped with thermal cameras can capture infrared images of the Earth’s surface, which can reveal thermal anomalies associated with geological features, hydrothermal systems, or environmental changes.
- Hyperspectral surveys: Hyperspectral sensors mounted on drones can capture data across a wide range of wavelengths, allowing for detailed analysis of surface materials and vegetation cover. This information is valuable for mineral exploration, environmental monitoring, and agricultural applications.
Drone geophysical surveys offer several advantages over traditional ground-based surveys, including rapid data collection, high spatial resolution, and accessibility to remote or inaccessible areas. Additionally, drones can operate at low altitudes, providing detailed data coverage and reducing the influence of environmental noise.
Overall, drone geophysical surveys are becoming increasingly popular in various industries, including mining, environmental monitoring, infrastructure inspection, and scientific research, due to their efficiency, cost-effectiveness, and versatility.

2. Water Detector and GeoSeeker Mini
Like the water detector OKM GeooSeeker, the GeoSeeker Mini utilizes a geoelectrical measurement procedure based on Schlumberger. The water detector – that can also be used to detect underground cavities – determines the soil resistivity. Based on that apparent resistivity of the ground the detector is able to detect underground water resources like fresh water, drinking water, water-bearing gravel and groundwater level.
Based on the fact that underground water has a very good conductivity, you can conclude that very bad conductivity is a hint for hidden cavities like caves, tunnels, chambers and underground rooms. Thus, the geophysical detector GeoSeeker Mini can be deployed as water finder and cavity detector at the same time.
Operating the water and cavity detector GeoSeeker Mini
The water detector GeoSeeker Mini is operated via touchscreen. Select the measurement depth as well as the amount of scanning points and simply follow the graphical instructions. Due to easy-to-understand images and icons, the GeoSeeker Mini is multilingual by using pure picture language.
During the measurement the electrodes have to be replaced several times to measure the ground resistivity at certain places. All instructions can be read from the color display, where the results are presented after each single scan. At the very end of a measurement the final result is shown as a graphical 2D scan image.
Data visualization of water resources and cavity
After finishing a geoelectrical measurement, the final result is calculated to generate a representative 2D scan image of the underground resistivity. With the pictograms in the lower display area, users can read directly the diagram: The colors in the scheme indicate water deposits (blue with water drops) and/or detected cavities (red with tunnel symbol).
