DATA ACQUISITION
Component of Data Acquisition
1. Survey Method, Systems and Software
•selection of vessels that comply with particular criteria and specifications
•Setup, integrated and survey systems verification and calibration
•Importance of correct installation and data communication of sensors at the vessel
•Acquisition system time-stamping strategy with appropriate offset determination
•Line planning and method of maintaining survey vessel or survey system on a planned line
3. Survey Operation
•Roles and relationship of following survey parameter: positional accuracy, survey speed, line orientation, interlines, cross lines,
fix interval, coverage and data quality
4. Quality Control
•Quality control of data and quality assurance of survey operation
5. Documentation
•Create documents and data that associated with survey procedure in alignment with requirements.

COMPLETE COVERAGE MULTIBEAM
General guidance on grid resolution based on average depth (Office of Coast Survey, National
Oceanic and Atmospheric Administration/NOAA)
The grid resolution for water depths greater than 320 shall be 5% of the water depth, not to
exceed 32 m resolution.
For singlebeam sonar as the primary sounding technique → Gridded at 4 m resolution, regardless
of depth.
