Aerial Ground Survey with DroneRover
DroneRover turns a DJI Phantom 4 Advanced into a professional aerial ground survey system. Where a handheld detector covers a few hundred square metres per hour, DroneRover maps thousands of square metres per battery charge — from the air.
What DroneRover Detects
DroneRover uses a 3D magnetic sensor to detect anomalies in the Earth's magnetic field:
| Target type | Examples |
|---|---|
| Buried metallic objects | Iron, steel, non-ferrous metals |
| Non-metallic buried objects | Voids, underground spaces, tunnels |
| Geological anomalies | Irregular mineral formations |
| Archaeological features | Buried foundations, ditches, pits |
Coverage Per Flight
| Flight altitude | Resolution | Approximate area per battery |
|---|---|---|
| 10 m | Low | 5,000–10,000 m² |
| 10 m | High | 1,000–3,000 m² |
| 2 m (manual) | Low | 1,000–2,000 m² |
Lower altitude gives stronger sensor readings but covers less area per flight.
Who Uses DroneRover?
- Treasure hunters and prospectors scanning large tracts of remote land
- Archaeologists and heritage surveyors mapping sites before excavation
- Farmers and landowners locating buried infrastructure or old wells
- Researchers requiring non-invasive ground survey of large areas
How It Works
- Mount the DroneRover sensor unit on your DJI Phantom 4 Advanced
- Open the DroneRover app and draw your scan area on the map
- Launch — the drone flies the area autonomously
- Watch the 3D heat map build in real time on your iPhone
- Land and review — red/warm zones indicate the highest-probability targets
Requirements
- DJI Phantom 4 Advanced drone (sold separately)
- iPhone 6 or newer running iOS
- Open outdoor area with stable GPS signal
