Hydrographic surveys are integral parts of the planning, design and operation of harbours, navigation channels and terminals. Survey activities aim primarily at establishing baseline information.  Measurements of waves and currents, for example, are crucial for the verification and calibration of numerical models used for design event studies.

DHI has the relevant experience in hydrographic and geodesy surveying and monitoring. Advanced survey equipment utilised in hydrographic surveys in Malaysia and Singapore have included: Differential Global Positioning systems (DGPS), Acoustic Doppler Current Profilers (ADCP), echosounders, sediment sampling equipment and processing software/hardware and data analysis and presentation software.
