PROCESS AND

METHODOLOGY

Our Process

At GGM.EARTH, we approach every project with a structured, four-stage workflow that ensures reliable, science-based outcomes. From precise field surveys to in-depth data analysis and interpretation, we strive to deliver comprehensive reports tailored to each client’s objectives.

  • GGM.EARTH begins every project with a precise on-site or remote (drone/satellite) survey. Using advanced tools such as GNSS, total stations, LiDAR, or geophysical sensors, we collect high-quality data tailored to each project’s unique objectives.

  • Once the raw data is captured, our specialists refine and organize it through processing software (GIS platforms, 3D modeling suites, geophysical analysis tools). This step ensures that noise is removed, accuracy is maximized, and all relevant geospatial layers are properly integrated.

  • With cleaned and structured datasets in hand, our experts synthesize information to identify patterns, anomalies, or key insights. Here, geologists, geophysicists, and engineers collaborate to draw meaningful conclusions—essential for informed decision-making, risk assessments, or design recommendations.

  • Finally, we compile a comprehensive report that details methodologies, results, and critical findings. Clear visualizations (maps, 3D models, graphs) and actionable recommendations are included, ensuring stakeholders can easily understand the outcomes and implement any necessary next steps.

Methodologies

At GGM.EARTH, we use a comprehensive suite of geophysical and remote sensing techniques to analyze, visualize, and understand the subsurface and surrounding environment. Our methodologies allow us to gather crucial data for projects involving infrastructure monitoring, environmental assessments, heritage preservation, risk analysis, and more.

1. Resistivity Method

  • Principle: Measures the electrical resistance of soil and rock layers.

  • Application: Creates two-dimensional (2D) or three-dimensional (3D) resistivity profiles that help identify subsurface characteristics such as moisture content, voids, or changes in composition.

2. Seismic Method

  • Principle: Utilizes seismic waves—either generated artificially (active) or naturally occurring (passive)—to explore the subsurface.

  • Data Collection: Geophones record direct, reflected, refracted, and surface waves, enabling the creation of 1D, 2D, or 3D models.

  • Use Cases: Determining layer thickness, identifying fault zones, and assessing dynamic soil properties for engineering and construction.

3. Ground Penetrating Radar (GPR)

  • Principle: Emits high-frequency electromagnetic waves into the ground; reflections vary based on material properties and boundaries.

  • Outcome: Captured signals are converted into 2D radargrams, from which 3D maps and models can be derived.

  • Typical Applications: Locating buried utilities or objects, mapping shallow geology, and detecting changes in soil composition.

4. Magnetic Method

  • Principle: Measures natural variations in the Earth’s magnetic field caused by magnetic materials in the subsurface.

  • Application: Produces anomaly maps useful for identifying metallic objects, geological structures, or mineral deposits.

5. Electromagnetic Method

  • Principle: Investigates the subsurface by measuring its response to an induced electromagnetic field.

  • Data Interpretation: Conductivity variations are mapped to highlight different materials or fluid content.

  • Common Uses: Mapping soil salinity, delineating contaminant plumes, and detecting voids or buried features.

6. Sonic/Ultrasonic Method

  • Principle: Employs high-frequency sound waves to evaluate internal properties of materials (e.g., thickness, density, and structural quality).

  • Extension: Includes sonar technology for bathymetric (underwater) surveys.

  • Benefits: Provides quick, non-destructive insights into concrete integrity, bedrock profiling, and underwater terrain.

7. MONITOR MAPPING

  • Principle: Gathers geospatial data via satellites or drones, using active (radar, LiDAR, sonar) and passive (multispectral, hyperspectral) sensing.

  • Scale & Resolution: Satellite imagery offers global coverage for large-scale monitoring; drone-based data collection yields high-resolution results for smaller areas.

  • Techniques: InSAR, LiDAR, sonar, and spectral sensors detect surface and submerged features, monitor changes over time, and map land use. Data outputs include high-detail maps, images, and 2D/3D models.

8. Gravimetric Method

  • Principle: Measures variations in the Earth’s gravitational field related to density contrasts in the subsurface.

  • Outcome: Pinpoints geological anomalies such as voids, fractures, or ore bodies.

Integrated Solutions for Complex Challenges

Looking Ahead: Monitor Mapping & Geomatics

In addition to the established geophysical and remote sensing approaches, GGM.EARTH integrates two evolving fields that unify and extend these methods: Monitor Mapping and Geomatics. By combining real-time data tracking, advanced geospatial analysis, and high-precision surveying into one cohesive framework, these disciplines offer a dynamic, holistic view of both natural and built environments. They build on the core techniques outlined above—reshaping how we collect, interpret, and respond to critical data, and setting new standards for modern geoscience solutions.

By combining these methods—often in multi-sensor and multi-scale approaches—GGM.EARTH delivers robust datasets for engineering design, risk mitigation, resource exploration, and environmental management. Each technology is carefully selected and calibrated to provide the most accurate, cost-effective insights possible, ensuring that every project receives a custom-tailored approach.
