DIWA Ground Penetrating Radar

Ground Penetrating Radar

Ground-penetrating radar uses electromagnetic radiation to create images of sub-surface features, with applications including mineral exploration and prospecting, civil engineering, construction management and archeology. Drones are known for their ability to access locations that may be difficult or dangerous to reach and provide essential data about these locations without risk to people on the ground.

GPR Benefits

What is Ground Penetrating Radar?

Ground Penetrating Radar (GPR) is a geophysical method that uses electromagnetic radiation to image the subsurface. It’s a non-invasive technique that can be used on any surface, even water. GPR works by sending out radio waves into soil and rock, then recording their reflections from interfaces between materials of different dielectric properties – such as between soil and bedrock or minerals in rocks. By looking at these reflections, it’s possible to map structures within materials. ​

Why do We Need It?

Hovering just 1m meters above the ground, DIWA is able to automate flight plans and cover a large area in a single flight with true terrain following. The GPR works very well, allowing for high-quality data on rock formations.

How Can Drones Help?

Drones' benefits to companies are numerous; DIWA can use them to inspect machinery, improve security at mine sites, and check up on equipment. But there’s one use of drones in particular: no company should be without GPR (ground penetrating radar). As seen in recent research conducted by Drone Inspections WA (DIWA), GPR is a game-changer for companies looking to improve their processes.

Drone Use Cases in Geology

Ground-penetrating radar is an automated geophysical method that detects subsurface features by sending pulses of radiofrequency energy into geologic materials and recording their reflected signals. GPR is used in many applications, including archeology, building foundation inspection, structural analysis, forestry, mining operations, environmental protection, land surveying and geohazards. In addition, the high penetration depth capability of GPR makes it well-suited to detect objects at depth under challenging conditions.

Data Interpretation

Comprehensive Survey Integration

Together with our partners, we gather valuable insights into geological formations by integrating LiDAR, aerial imagery, Open File DMIRS Data, Geoscience Australia Data, and geophysical data. This approach allows detailed analysis and interpretation, facilitating informed decision-making for route planning and infrastructure development and enhancing efficiency by reducing the time and costs associated with ground surveys


Enhanced Data Fidelity

LiDAR and high-resolution imagery from our  Airborne Survey ensure high-fidelity analytics. Ground truthing from completed route sections validates data interpretation, ensuring accuracy and reliability.

Risk Mitigation in Trenching Operations

Understanding sub-surface conditions helps identify obstacles like shallow bedrock or boulders. This information allows route adjustments, avoiding costly delays and damages during trenching. Aggregated geophysics data with airborne LiDAR and imagery provide a macro-level geological interpretation, optimising trenching logistics.

Advanced Geophysical Interpretation

Using advanced techniques, we translate aggregated data into geological maps and profiles, offering invaluable insights for optimising projects. Our detailed terrain descriptions indicate sub-surface conditions for both shallow and deeper exploration.


Critical Applications and Benefits

For building large structures, digging trenches, or running high-voltage power infrastructure, shallow sub-surface information is crucial. Our approach assists in finding critical minerals, measuring biomass for carbon sequestration, and building better intelligence about the earth.

Unmatched Professionalism

We are committed to professional survey management, validated quality control, and achieving exceptional outcomes. Our clients receive top-quality data interpretation and project planning support.
