Professional GPR Data Processing & Interpretation Service

Got the Data But Not the Answers?

If you own a Ground Penetrating Radar (GPR) system and have collected data in the field, but need expert support to process, interpret, and make sense of your radargrams, this service was built for you.

At Cartomex, we offer a service that is surprisingly hard to find anywhere in the world: remote GPR data processing and interpretation. Regardless of what equipment you use or where you are located — send us your radar files and our team of geophysicists with over 20 years of GPR experience will transform your raw data into a clear, professionally processed report ready for decision-making.

Reference Pricing

We publish our base prices so you can factor processing costs into your budget from the planning stage:

Note: Prices are base references. Final quotes depend on project complexity, data density, specific application, and required deliverables. High-volume projects (>50 linear km) receive significant discounts.

Who Is This Service For?

This service is designed for professionals and companies anywhere in the world who:

• Own a GPR system but lack the experience or specialized software for advanced data processing and interpretation.
• Have completed a field survey and need expert support to extract meaningful information from their radargrams.
• Need a second opinion on previously processed data or results that raise questions.
• Must deliver a professional-grade technical report to their end client but don't have the in-house capability to produce one.
• Municipalities and governments that acquired GPR equipment and need a permanent technical partner for data processing.

Whether you're a civil engineer who uses GPR occasionally, a contractor who recently purchased a system, a geotechnical services company, or a municipality implementing a road monitoring program — we can be your GPR processing department.

Our Process: From Your Raw Data to a Professional Report

1. 1. Data Reception and Project Context

   You send us your radar files along with the survey context information:

   • Original data files in any format.
   • Project description: What were you looking for? Utility detection? Rock mapping? Concrete inspection?
   • Line distribution sketch or plan of GPR lines.
   • Site photographs to help us understand the terrain.
   • GPS data if available.

2. 2. Professional Digital Processing

   We apply a processing workflow tailored to the specific conditions of your GPR data:

   • Time-Zero Correction: Aligning the true start of each trace for accurate depths.
   • Filtering: Removing electromagnetic noise and unwanted signals.
   • Gain: Compensating for signal attenuation with depth.
   • Background Removal: Eliminating clutter that masks targets of interest.
   • Migration: Collapsing diffraction hyperbolas for greater spatial accuracy.
   • Depth Conversion: Transforming time to depth with calibrated velocities.
   • 3D Processing: Horizontal slices (time-slices) when line density permits.
3. 3. Geological Context Research & Background Investigation

   Before interpreting a single radargram, we do what nobody else does: we thoroughly research the geological setting of your study area. We don't just process signals — we seek to truly understand what is happening beneath the surface.

   • Regional geology: We consult geological maps, formation charts, and previous studies of the area.
   • Site history & antecedents: Previous studies, construction records, incident reports, historical data.
   • Hydrogeological conditions: Water tables, flooding history, drainage problems.
   • Known hazards: Sinkhole history, landslides, geological faults, karst zones.
   • Existing infrastructure: Utility plans, network records, subsurface installations.

   This preliminary research is what allows interpretation to have real geological meaning — not just geophysical.

4. 4. Interpretation by Experienced Geophysicists

   With the geological context established, this stage becomes a true subsurface diagnosis:

   • An experienced geophysicist analyzes each radargram in light of the investigated geological information.
   • Targets are identified, classified, and marked: pipes, geological interfaces, anomalies, voids, cavities.
   • Interpretation is grounded in concrete geological evidence, not assumptions.
   • When data warrants, we correlate GPR findings with other geophysical techniques.
5. 5. Deliverables

   Standard Deliverables:

   • Processed radargrams in high resolution, with scales and identified targets.
   • Interpretive technical report with findings, subsurface conditions, and conclusions.

   Additional Deliverables (based on data availability):

   • Georeferenced plans with location of findings.
   • 3D Slices (Time-Slices) from the three-dimensional model.
   • Digital files in formats compatible with major GPR software.

A Global Crisis: Why the World Needs Professional GPR Processing

Sinkholes, subsidence, and road collapses are not any one country's problem — they are a global infrastructure crisis that worsens every year. GPR is the tool that can prevent them, but only if the data is interpreted correctly.

The Sinkhole Epidemic: Alarming Numbers

Japan records approximately 10,000 road sinkholes per year — an average of 27 collapses per day. In January 2025, a sinkhole in Yashio (Saitama) swallowed a delivery truck, killing its driver. The crater grew to 40 meters in diameter. The cause: deteriorating buried pipes — the same pattern repeating worldwide.

Mexico faces the same crisis. Mexico City recorded over 160 sinkholes in 2025, with 85% caused by leaks in water networks over 50 years old. The most emblematic case is the Puebla Sinkhole: in May 2021, a 5-meter hole grew in just 14 days to reach 126 meters in diameter and 45 meters deep, swallowing an entire house. The cause: dissolution of limestone — a process that GPR could have detected.

China, the United States, Spain — the pattern is global. In Florida, dedicated GPR programs detect sinkholes in karst zones. In Zaragoza, Spain, an active sinkhole has caused losses exceeding 15 million euros.

Why Professional Processing Matters

All these cases share a pattern: the signals were in the subsurface before the collapse occurred. Saturation zones, developing cavities, internal erosion — anomalies that GPR can detect. But a raw radargram says nothing on its own. The difference between preventing a disaster and just having data on a hard drive is professional interpretation.
