Precise Underwater Mapping & Hydrographic Data Collection
At Geopin Consult, we specialize in comprehensive bathymetric survey services for underwater mapping, hydrographic data collection, and marine infrastructure assessment. Our advanced bathymetric systems use multi-beam sonar, single-beam echo sounders, and sub-bottom profilers to accurately map underwater terrain, water depths, and submerged features.
Our bathymetric surveying services are essential for port and harbor development, dredging operations, underwater pipeline routing, dam and reservoir management, coastal engineering, and environmental monitoring. With state-of-the-art equipment and experienced hydrographers, we deliver precise underwater data for critical infrastructure projects across East Africa.
We follow a systematic approach to ensure every bathymetric survey delivers accurate, reliable underwater data:
1. Project Planning & Mobilization: We begin by understanding project requirements, reviewing nautical charts, and planning the bathymetric survey methodology. Our team determines optimal equipment configuration, line spacing, and data collection parameters.
2. Equipment Setup & Calibration: We deploy multi-beam or single-beam sonar systems, calibrate echo sounders, and integrate with RTK-GNSS positioning for centimeter-level accuracy. Tide gauges are installed for water level corrections.
3. Hydrographic Data Collection: Our certified hydrographers conduct systematic surveys using survey vessels equipped with advanced bathymetric systems. We collect comprehensive underwater data along predetermined survey lines.
4. Data Processing & Analysis: We process raw bathymetric data using specialized hydrographic software to create digital terrain models (DTMs), contour maps, cross-sections, and volumetric calculations. Our team analyzes the data for navigation hazards, sediment accumulation, and underwater features.
5. Deliverables & Reporting: We prepare comprehensive bathymetric survey reports with 3D visualizations, depth maps, volumetric calculations, and GIS-compatible data. Our deliverables meet international hydrographic standards (IHO S-44) and include recommendations for engineering or environmental applications.
We operate advanced multi-beam sonar systems for high-resolution underwater mapping with up to 100% seafloor coverage.
Our survey vessels are equipped with integrated positioning systems, motion sensors, and sound velocity profilers for accurate data collection.
All bathymetric data is integrated with RTK-GNSS positioning for centimeter-level accuracy and seamless integration with terrestrial surveys.
Our hydrographers are certified and experienced in bathymetric data collection, processing, and interpretation according to IHO standards.
