HYDROGRAPH LTD provides professional hydrographic surveys, bathymetric mapping, seabed investigation, navigation safety assessments, and marine data processing. From field measurements to final chart-ready deliverables.
From field measurements and positioning control to bathymetric processing, seabed interpretation, chart production, and technical reporting.
Professional single-beam and multibeam bathymetric surveys for ports, coastal zones, rivers, lakes, engineering sites, and navigation channels.
Accurate depth models, contour maps, seabed relief visualisation, and digital terrain models prepared for engineering and navigation tasks.
Survey and documentation of approaches, fairways, berths, underwater hazards, shallow areas, and critical zones affecting safe vessel movement.
Detection, positioning, and documentation of seabed features, debris, underwater objects, anomalies, and engineering constraints.
Cleaning, correction, interpretation, visualisation, and integration of hydrographic, geodetic, acoustic, and cartographic datasets.
Clear survey reports, charts, profiles, coordinate tables, GIS-ready deliverables, and documentation for clients, engineers, and authorities.
Hydrography is the foundation of safe navigation, responsible engineering, port development, dredging control, coastal planning, and underwater infrastructure projects.
HYDROGRAPH LTD combines field survey practice, positioning control, bathymetric data, and cartographic interpretation into clear deliverables that engineers, vessel operators, and authorities can use with confidence.
Our workflows integrate multibeam echosounder, single-beam sounder, sub-bottom profiler, and positioning data into a single co-registered dataset — enabling detailed analysis of seabed morphology, depth variations, sediment structure, and underwater features.
All surveys are conducted to IHO S-44 standards and delivered in client-ready GIS, CAD, and cartographic formats. From port inspections to open-water bathymetric campaigns — precision from first sounding to final chart.
We convert field measurements into practical cartographic products: bathymetric charts, depth contours, seabed models, survey plans, profiles, and technical documentation.
Our cartographic output covers the full spectrum of hydrographic deliverables — from engineering survey drawings and dredging control grids to official nautical chart supplements and GIS/CAD-ready data packages. Every chart-ready product is validated against source data, georeferenced, and documented for client use.
Full-coverage depth surveys using calibrated multibeam and single-beam echo sounders. Production of depth contours, digital terrain models, and chart-ready bathymetric products.
High-resolution mapping of berths, quay walls, breakwaters, and approach channels. Dredging volume calculations, sedimentation monitoring, and infrastructure documentation.
Survey and documentation of fairways, waterway profiles, sounding lines, and navigational constraints. Deliverables formatted for navigational planning and port authority use.
Pre-lay route assessment and as-built surveys for submarine pipelines and cables. Detection of free spans, crossings, and burial depth using acoustic and sub-bottom methods.
Seabed classification and coastal morphology mapping for engineering impact assessment, coastal zone planning, and shoreline change monitoring using acoustic and positioning data.
Structured, client-ready output in GIS and CAD formats. Coordinate tables, survey grids, track plots, depth models, and technical documentation for engineering and planning use.
Sounding lines, depth contours, and seabed relief visualisation.
Precision instruments for field measurements and data acquisition.
Equipment deployment and data acquisition during active survey.
Side-scan sonar records of underwater features — wrecks, pipelines, seabed anomalies, and survey targets from active hydrographic operations.
Sub-bottom profiler records and multibeam bathymetric models from survey operations.
HYDROGRAPH LTD processes field data into verified, structured, and client-ready deliverables for engineering, navigation, and marine planning.
Systematic noise filtering, tide correction, sound velocity profile application, and outlier removal from raw sounding data to produce verified depth measurements.
Construction of digital terrain models, seabed relief grids, and depth surface products from processed sounding data. Resolution from 0.1 m to survey-area scale.
Generation of depth contours, isobaths, sounding plans, and chart-ready cartographic products from bathymetric datasets compliant with IHO S-44.
Structured export to GIS layers, CAD drawings, coordinate tables, and technical documentation packages ready for client engineering and planning workflows.
A structured hydrographic workflow — validated, publication-ready deliverables every time.
Define survey area, depth range, accuracy spec, and deliverable format.
Sensor selection, vessel mounting, sound velocity profiling, and calibration.
Survey execution with real-time QC, positioning control, and data logging.
Cleaning, filtering, georeferencing, and bathymetric model generation.
Charts, depth models, GIS layers, profiles, and technical report.
Multibeam echosounder depth models, sub-bottom profiler records, and calibration data from active hydrographic survey operations.
