High-resolution bathymetric mapping is essential for navigation safety in coastal zones, especially in shallow waters.
Mapping techniques like sonar, satellite-derived data, and autonomous vehicles offer varied benefits; resolutions can be less than 1 meter.
Multisource coupling of different mapping technologies may provide the most accurate and comprehensive bathymetric data.
Techniques used should be dictated by local conditions and specific mapping needs to effectively address hazards in shallow environments.
